Scootie has a formula for thyroid. Is this the same formula? In a message dated 12/26/2004 12:36:43 P.M. Central Standard Time, BarMarGSD@xxxxxxxxxxxxxxxx writes: The first thing you want to do is calculate the 50% mark of the "Normal Range" for each panel (T4, T3, Free T4, Free T3, T4 Antibodies and T3 Antibodies). Each panel will have a "Normal Range" associated with it. If you have had Dr. Dodds do the testing, there should be a second page that also lists her personal ranges. She adds these based on your dog's age and breed (and they tend to be more conservative than even the laboratory's ranges). Try this method with both the Lab's ranges as well as Dr. Dodds'. To calculate the 50% point you add the end values of the range and divide by 2. Here is an example: T3 Lab "Normal Range" = 45 - 150 45+150 = 195 195 / 2 = 97.5 97.5 = 50% of the "Normal Range" Therefore, if your dog's T3 level was less than 97.5 in this instance, he/she would be below 50% of the range. You need to do this calculation and comparison of these percentages with each of your dog's test results ( T3, T4, Free T3, Free T4). If your dog falls below the 50% mark of these ranges, you should speak to your Vet (and you can also call Dr. Dodds to get more information) about supplementing your dog on Soloxine (the thyroid supplement).
