the lab should still have the blood if you want a full thyroid panel. the vet should be able to call them and order it up for you.
The bloodwork was done April 2nd.
And it's not that the vet won't do the testing, it's that I didn't look at what had been done until getting home. When we did the T4, I didn't even realize we were doing a thyroid test. Yesterday, I asked the vet if we had checked his thyroid and the vet said yes and it was normal. It wasn't until later that I realized we had only done the T4 and that while it is normal, it's near the low end of normal.
