You need to get copies of ALL of her bloodwork (all of the panels that were run so that you can compare how they may have changed from one test to the next). Not all vets are great at interpreting bloodwork. For instance, if your cat's T4 thyroid level is in the high normal range, your vet may assume that's normal and not do any further testing. But a high normal T4 level may, indeed, occur in a cat who is hyperthyroid, and the only way to discover the accurate diagnosis is to do more extensive thyroid testing.
So get copies of all of her bloodwork from your vet and post the results here so that we might be able to offer you more suggestions. Also, you might consider consulting with a veterinary hematologist who can analyze her bloodwork and provide you with more specialized insight into her test results.
In the meantime, I recommend you switch your girl to a calorie-dense diet of Innova EVO or Wellness CORE dry and prescription A/D canned foods to help pack on the calories. Also, if your vet has prescribed prednisone as an appetite stimulant, there are a lot safer alternatives (cyproheptadine is one with which I have had good results), so you should discuss that with your vet. Do NOT, however, stop giving the pred unless your vet directs you to do so. Pred must be slowly weaned out of a cat's system in order to avoid potentially serious side effects.
