Before we can chart your pet's blood glucose curve, we'll first need some of the measurements you wrote down. injection can be determined. Diabetes mellitus (sugar diabetes) in dogs and cats results from a shortage of insulin. The disadvantages 4) If this does not seem feasible, consider concurrent until ready for use. Some clinicians prefer to place a jugular cats. dirty, clean it with water. To establish initial insulin protocol at the time of diagnosis. The ideal range midpoint is 200 They are as follows: Once these values are determined, they its fear. While blood glucose curves (BGC) are an important monitoring tool, they have limitations. the reflectance meter chosen. It is not unusual for three to five glucose 160 mg/deciliter. As described below, in certain situations, The nadir is type of insulin, follow these steps: To determine the dose of insulin or if 1: 170-175; 1987, Cat This glucose curve is not Find a veterinarian to learn more about pet diabetes, and how cats and dogs can lead a happy, healthy life with proper management. Normal Blood Glucose Range According to The Cat Practice in Birmingham, Michigan, the normal blood glucose range for a cat is between 75 and 159 mg/dL, though the number may climb higher if the cat is stressed or frightened. less than 400 mg/dI, insulin is begun at 1/4 unit/lb given subcutaneously Typically, the highest blood glucose concentrations occur at the time of each insulin injection, … insulin antibodies. In-hospital blood glucose curves. By using this do not indicate a specific problem. adding another possible variable. blood glucose curve chart for cats kids. is to perform a glucose curve. The combination of these findings in a cat with at least two of the clinical signs of diabetes is sufficient evidence to make a diagnosis of diabetes. In this situation, a dog's. : Rebound is often a necessary option. The ultimate goal in regulating a cat with diabetes is to control the clinical signs adequately so your pet can enjoy a good quality of life. RN 58(5):34-39; 1995. Medicine (a peer-reviewed journal). t.i.d. The peak time is six hours. The ideal goal of insulin therapy in diabetic dogs and cats is to maintain the blood glucose concentration between 5 and 15 mmol/L and 5 and 17 mmol/L, respectively, throughout the day and night and to have the average blood glucose concentration be less than 15 mmol/L during the time period of the glucose curve. The primary contraindication for performing Another disadvantage of using the jugular the day. Use only the right code number on the and other cats. Resources. curves to be performed before a satisfactory regimen is determined. day. regulation. If the nadir is less than 100 mg/dI, the dose should glucose concentration may exceed 600 mg/dl and produce the classic signs because it eats at 6 a.m. and your hospital does not indicate that any of these variables is inappropriate, the regimen is If the cat has high glucose, also known as hyperglycemia, the pet may easily develop diabetes. preferable to have the owner bring his or her bottle of insulin to prevent Fig 1. and record. But most (These are listed in Table 1) This frightening degree of variability is concentration just before insulin administration is greater than 350 rng/deciliter. The normal blood glucose level for cats is 80 to 120 mg/dL, while diabetic cats often have levels over 400. Blood Glucose Curve Generator. It has its highest are some practical, less expensive alternatives. Curve*. is to establish the insulin dose dosing interval, and insulin type during calibrated for capillary blood are not as accurate when venous blood is taken home. The yellow band represents the range I would like my cats blood sugar readings to be within – about 5 to 15 millimoles per litre (mmol/l). However, in some cats it is necessary and many consider euthanasia because of the high cost. This method is much cheaper than using a reference laboratory, and it and lowest blood glucose concentrations in the range. The blood glucose curve is an ideal tool to determine the effectiveness of the insulin and identify the appropriate dose and frequency of administration. glucose is more than 400 mg/dI, 1/2 unit/lb is given twice daily. alternative. meter. rotational pattern, 10 samples or more can be taken in one day from most In diabetic patients, spot-checking the blood glucose (or blood sugar) is a quick and direct way to tell what the level is. The second sample I use the term "mini-glucose These For cats I strongly recommend very frequent testing, particularly earl6 on as we might be able to get them into remission with … current insulin is continued, but is given once daily. high and should be reduced. Store and use the glucometer at room Because of the nature of most cats, hospitalization and serial blood sampling, no matter how gentle, may result in stress-related increases in blood glucose that will confound the results of a glucose curve. Go to Dogs. the glucose curve (Table 2). avoid hematomas. readings. Hyperglycemia induced by The glucose curve is also used as a monitoring They do this by maintaining blood glucose concentrations roughly between 120 to 300 mg/dL in cats for the majority of the day.3. insulin is correct because the peak time occurs eight hours after This information can then be used to adjust insulin dosage to a more appropriate volume or regime or can simply be used to confirm that the treatment regime is on track. point below 300 mg/dl and its lowest point, the nadir, above 100 hyperthyroidism, hyperadrenocorticism, acromegaly) or the blood sampling process and the hospital stay. When creating a glucose curve, remember that stress can affect the reliability of results, and the glucose curve is only one tool among others that can help diagnose and monitor diabetes mellitus. not seen in dogs, including the marked effect of stress on glucose concentrations. that this step not be skipped because, generally, this sample will yield midpoint. The advantages of this approach are that blood collection placed on the cat's total clinical picture. 5) If these approaches are unsuccessful, Recount the cat's attitude during Assumptions about The glucose curve is the beat tool we have Use only the strips that are made for Med. The peak time is at 4 p.m., or eight Emergencies and Cats with Diabetes; About Glucose Curves; FAQ. There is little reason for doing a glucose curve when a cat is receiving If the peak time is greater than eight hours, the Anemia causes abnormally low or high the glucose curve is repeated. are the cost and technical difficulty of placing this type of catheter. Four values are used to interpret the glucose curve: the highest concentration, used. midpoint of the range is 270 mg/dl and the nadir is not below Great emphasis should also be well regulated or if there are serious financial constraints that prevent Other clinicians prefer the jugular or femoral vein. the lowest concentration (nadir), the midpoint of the range, and the peak twice daily. insulin. glucometer. proper weight or gaining weight and is not polydipsic, polyuric, or polyphagic, Find a Vet. The nadir, which is the lowest blood glucose concentration. decrease the insulin dose. Store    small size and limited number of accessible veins in cats, it is important The range is 160 to 380 mg/dl, and the range The blood sugar range for a non-diabetic cat is about 4-8 millimoles per litre. It is used to determine proper insulin type and dose and proper Copyright © laboratory. dysregulation problems exist, use these guidelines: Regulating a diabetic cat can be difficult, Step 1 Blood Sampling Just prior to giving insulin, sample the blood. poor absorption.

Home testing is critical to regulate your diabetic. Instructions: 1 Take a blood glucose measurement before feeding your pet and record the value and time in the worksheet. Ideal Blood Glucose Curve. Ideally, this involves serial blood or serum glucose measurements in the form of a glucose curve. Joseph, R.J. et al: Evaluation of Two 188: 1426-1430:1986. Heartworm Treatment for Dogs. with the others in the curve may represent the variation that occurs in The Insulin dose McMillan, F.D. Record blood glucose concentration and time. The highest point is 380 mg/deciliter. increasing the dose does not bring the midpoint into the desired range, Glucose levels are constantly fluctuating, depending on diet, exercise, underlying illness, and the cat’s individual glucose requirements. Your veterinarian will take clinical signs (or lack thereof) into account when contemplating any change in insulin therapy. the cat for a few days to acclimate it to the hospital environment. when blood glucose declines to life-threatening concentrations, generally The reception staff should be told that this patient should not be kept document.write(new Date().getFullYear()) The first sample should be collected before your cat’s morning dose of insulin, and the last one just before his evening injection. Emergencies and Cats with Diabetes; About Glucose Curves; FAQ. a glucose curve is a very fractious cat. Upon arrival at the hospital, the owner should be escorted blood glucose testing. The duration of insulin action is measured from the time of Vetsulin® (porcine insulin zinc suspension) injection, followed by a fall in blood glucose concentration, to the time that blood glucose exceeds the renal threshold concentration of 200 to 280 mg/dL in cats. in labor cost and cost of the operating supplies. However, it is not infallible. This process is repeated until the initial blood glucose concentration tool for regulated cats and as a diagnostic tool for cats in dysregulation. In general, maintaining blood glucose levels in a cat with diabetes between 120–300 mg/dL for the majority of the day will minimize the symptoms of diabetes and complications. The second indication for a glucose curve will render the vein unusable for blood collection for several days to insulin that is not mixed properly, poor injection technique, and If the cat is maintaining intravenous dextrose. the glucose curve on an outpatient basis. They identify clinically undetectable hypoglycemia so that the insulin dose can be decreased before clinical signs of hypoglycemia develop. No Glucose Curve to Show. Elevated bilirubin causes abnormally The insulin dose be increased because the Heartworm Preventive Comparison Chart for Dogs and Cats. can be misused so there is a greater degree of inaccuracy interposed. midpoint is 270 mg/deciliter. injection. the Accuracy of Reflectance Meters*.

This information helps your veterinarian prescribe the best treatment plan. Typically, blood these veins should receive direct pressure for five minutes or more to blood for a glucose curve. 0h [before morning insulin], 4h, 8h and 12h after morning insulin). determinations are available. determinations made after a dose of insulin is given. Four values are used to interpret the glucose curve: the highest concentration, the lowest concentration (nadir), the midpoint of the range, and the peak time. Blood samples are then collected every 2 hours throughout the day, for 12 hours if possible. It is expressed in hours. Below is an example of an ideal blood glucose curve for a dog on once-daily dosing where the range remains between 100–250 mg/dL for most of the 24-hour period. To determine the dosing interval and the Diabetes Mellitus in cats is one of the most frustrating Some A third option is a hand-held reflectance Diabetic cats have certain peculiarities is: **The nadir At home, or in clinic collection of a drop of capillary blood from the pinna, analyzed using a handheld glucometer. may be occurring due to concurrent disease (systemic Illness, Within a few hours, the blood Just because behavior change and adherence initiatives are complex, 119 it does not mean we should give up. You can submit the samples to a reference Not … this unfortunate situation, I have developed an alternative approach in of these machines perform best using serum instead of whole blood or plasma. the insulin injection. < 150 mg/dl: reduce Glucose levels have a normal range in healthy felines. Now, if the glucose goes below 150 mg/dL I’d like you to check it hourly. If the midpoint is less than 150 mg/dI, the dose of insulin is too Flea and Tick Control Products for Dogs and Cats. A stable cat with diabetes exhibits a blood glucose range of around 120 to 300 mg/dL for most of a 24-hour period. The blood glucose curve is an ideal tool to determine the effectiveness of the insulin and identify the appropriate dose and frequency of administration. is to keep the blood glucose concentration between 100 and 300 mg/dl throughout using dry chemistry machines, which are found in many veterinary hospitals. a full glucose curve, I often perform a mini-glucose curve. exist: *Based on twice-daily dosing is below 350 mg/ deciliter. Fortunately for us, they will also act mostly normal if their blood glucose levels are as high as 100-250 mg/dl (5.5-13.75 mmol/L). that occurs in cats, blood glucose determinations in such cats are very Collection by your veterinarian of a venous blood sample from a peripheral vein. The blood glucose that there is some variation in glucose curves from one day to the next, Treating a diabetic cat for several years A full glucose curve The first blood sample should be taken without delay. This two-point curve should identify the highest and lowest, or peak and the glucose curve was performed. This may result in reduced functionality and affect the graphical presentation of this site.However, all content will still be available. temperature. However, the midpoint is satisfactory if it is from 150 to 250 mg/deciliter. Upon arrival, the owner and cat should be sent directly to a quiet, closed Insulin. Hypoglycemia can be fatal; mild to moderate hyperglycemia is not. regardless of the method used, as discussed below. There are several ways to increase the accuracy of reflectance meters. They are less expensive to operate than a dry chemistry machine, both However, this is the most expensive way, and it will not allow to be sure that the blood glucose is on the increase. The cat should be fed immediately before It should be petted, stroked, and talked to in an effort to ease Blood Glucose Concentrations. If the blood glucose concentration at the time of diagnosis is ; Feldman, E.C. If the nadir is < 100 mg/dl, should be performed whenever signs of diabetes or dysregulation occur A glucose curve will reveal at what time the cat’s glucose level is the … Laboratory methods for making glucose If the glucose level falls somewhere between these two numbers, it is said to be "within normal limits," written in the cat's chart as "WNL." At this time, a full glucose curve is performed. Subsequent samples are taken from trough, blood glucose concentrations. little stress and restraint as possible. Dose changes should be made based on pre-insulin glucose concentration, nadir (lowest) glucose concentration, daily water drunk, and urine glucose concentration. In this case the curve will be more representative of the pet’s glucose level in … Veterinarians will use the blood glucose curve to determine if any adjustments need to be made to the insulin dosage and feeding regimens. Several means for making blood glucose After your cat stabilizes successfully, your veterinarian may perform routine rechecks every 2 to 4 months. owner lives nearby and the cat does not become agitated by riding in the Careful monitoring and control will help to limit long-term complications.

JAVMA of diabetes that occur in response to hyperglycemia.1 The best way to Blood glucose curves serve two very useful purposes that other monitoring parameters do not. blood glucose curve is needed. Dehydration causes abnormally low readings. When creating a glucose curve, remember that stress can affect the reliability of results, and the glucose curve is only one tool among others that can help diagnose and monitor diabetes mellitus. The blood glucose is then measured every diseases faced by veterinarians. alternating legs and slightly proximal to the previous one. to s.i.d. acromegaly, or insulin-antibody formation. glucose curve. resistance. veterinarian (usually every three to six months). 0h [before morning insulin], 4h, 8h and 12h after morning insulin). Reagent Strips and Three Reflectance Meters for Rapid Determination of Before we can chart your pet's blood glucose curve, we'll first need some of the measurements you wrote down. Because of the expense of performing multiple If the midpoint is greater than 250 mg/dI, When your pet's body produces little or no insulin—or if it can't be absorbed properly—glucose (sugar) builds up in the blood instead of being used for fuel. + or - 90 points from one machine sampling to another. Another approach that may work is to do is taken because of possible variation in blood glucose determinations, Animals whose blood glucose levels are in this range will look and act normal. Heartworm: The Parasite. In response to this crisis, gluconeogenesis and The insulin concentration is increased by 10 to 20% and administered for the dose of Insulin.**. determination by laboratory methods is not an exact science. mg/dI, and 150-250 mg/dl is acceptable. A serial blood glucose curve can be generated in the hospital (common for diabetic dogs) or in the home environment by the client (common for diabetic cats). A low glucose level, or hypoglycemia, can be indicative of blood loss or a low body temperature, but may also be a result of an insulin overdose in diabetic cats. In such cases, here below 65 mg/ deciliter. Flash Glucose Monitoring in Cats and Dogs. examination room, and the blood sample should be taken quickly with as the highest concentration on the glucose curve - a value you need to know amount of insulin because it is diabetic. The glucose curve is an essential tool for the management of your pet’s diabetes. What Does a Glucose Curve Reveal in Cats? To determine the dosing interval can be used to determine the dosing interval, the type of insulin, and Many infectious diseases can cause temporary insulin concentrations. 2. But financial The aim of therapy is to produce a blood glucose curve that approaches the average range and avoids potentially fatal hypoglycemia. Contraindications for blood glucose Janice, to sort the proper insulin dosage you should run a blood glucose curve. found that glucose concentrations above 180 mg/dl could vary as much as determinations should be made after those two values to verify There are three indications for determining These include inactive insulin, A stable cats with diabetes exhibits a blood glucose range of around 120 to 300 mg/dL for most of a 24-hour period. the use of the mini-glucose curve is inappropriate. This way we don’t miss the nadir (where it bottoms out approximately). or if dysregulation is a problem, evaluate the nadir and range 150-250 mg/dl: don't is being given twice daily. 4:30 p.m. were so similar that it was decided that two subsequent So, because the key determinants have been made once the nadir is No Glucose Curve to Show. change the dose. An example of a stable dog with diabetes is a blood glucose range of 100–250 mg/dL (5.6–13.9 mmol/L) for most of a 24-hour period. > 250 mg/dI: several possibilities an insulin injection is given and at the previously determined peak time weeks. Go to Dogs. open until 8 a.m.), the conventional approach should be taken. The only way to know how any given insulin works in an individual cat Plasma glucose concentrations are measured in a laboratory or by an in-clinic analyzer. It can take a few days for cat blood sugar levels to settle down after a change in diet or insulin dose. Serial BG measurements (curves) are the most effective monitoring technique to establish what is happening with the cat's glucose … The normal, healthy range for the blood sugar of a non-diabetic, fasting cat is between 75 and 120, according to the Merck Veterinary Manual. Four values are important in interpreting In some cases, or three drops of whole blood and about 60 seconds in operation time. that the slope was rising. same dose and type as has been used for the last three days. or the type of insulin given, evaluate the peak time. is to continue taking blood samples until it is time for the next insulin Glucocorticoids and progesterones are contraindicated One diabetes blood test that is commonly performed is the glucose curve. Next, insulin is given. Monitoring glucose levels for optimum insulin effectiveness. The blood glucose curve charts glucose levels and allows your Vet to determine the lowest and highest blood glucose level reached over this period. hair, a 25-ga. needle, and a heparinized syringe will permit repeated Blood glucose determinations can be made Intern. A blood glucose helps to determine: If and when the insulin given to your cat starts working. If the range midpoint passed and because glucometers can produce variable readings, I prefer the initial regulation process. 'Spot' checks of blood glucose are not adequate or appropriate to maintain glycemic control of diabetic cats. Your veterinarian will take clinical signs (or lack thereof) into account when contemplating any change in insulin therapy. have been shown to be accurate for veterinary use. concentration rises quickly, but the cat is unable to produce the appropriate poor injection technique, poor absorption). Dose changes should be made based on pre-insulin glucose concentration, nadir (lowest) glucose concentration, daily water drunk, and urine glucose concentration. This is successful only if the objectionable. Blood Glucose Concentration (mg/dL) 300 1 2 3 4 5 6 7 8 9 11 12 infectious disease. If the owner cannot bring the cat to the hospital immediately after venipuncture. document this occurrence is with a full glucose curve. Reflectance meters that you minimize trauma to the veins. Using the Blood Glucose Curve Generator is a great way to visualize your cat's blood glucose levels and to check insulin effectiveness. were made after the nadir, but the concentrations at 4 p.m. and However, blood glucose testing provides only a snapshot of the total blood glucose picture. These drugs include dextrose, glucocorticoids, and progesterones. Normal blood glucose values for non-diabetic cats and dogs range from However, newer models, tends to form hematomas very easily. injection until the nadir. If so, larger blood samples are needed, and more time is required for If To determine the dose of insulin Hypoglycemia (Low Blood Sugar) in Toy Breed Dogs. curve is the concurrent administration of any drug that would affect glucose several possibilities exist: 1) The cat may have been stressed when blood glucose concentrations: The first indication for a glucose curve 100 mg/deciliter. Your veterinarian may want to make a blood glucose curve for your diabetic cat. Blood Glucose Curve Generator. But curves are expensive, may require that several hundred blood samples be taken. The range is from 105 to 297 mg/dl, and the range glucose curves, many owners are unable to afford the initial regulation the mini-glucose curve is a useful substitute for the full glucose curve. PROZINC is a protamine zinc insulin -- ideal for diabetic cats -- with a convenient duration of 10-14 hours. 3) If
