I had a foster who tested via the Thyroid5 panel at hemopet to have hyperthyroidism which may indicate a cancer in some. He was tested right before arriving at his foster home and was quite active when he first arrived, running laps around the yard. We waited on further testing, giving him a couple of months to chill by the pool. He was pretty stressed out and confined in his previous home, so chill time really was needed. Two months later, another complete panel returned perfect mid-range normal results. No medication was ever used.
Thank you so much for your suggestions, the first test was at a 5.7 and I am awaiting the results of a second test. The initial blood test also revealed Diabetes Insipidus but I feel there is more to it than that and I see many of the symptoms of hyperthyroidism which i've read is usually results from medication for hypo and I had not given any such meds so it's a mystery how it was contracted. And we did lose her half brother in January which would explain added stress.
