My vet gave me the "norms" for thyroid in guinea pigs, from The Clinical Chemistry of Laboratory Animals textbook. I don't understand the units, but hopefully the numbers will help other owners and vets in diagnosing thyroid problems.
T4: male 2.9 +/- 0.6 ug/dL, female 3.2 +/- 0.7 ug/dL
T3: male 39 +/- 17 ng/dL, female 44 +/- 10 ng/dL
Free T4: male 1.26 +/- 0.41 ng/dL, female 1.33 +/- 0.25
Free T3: male 257 +/- 35 pg/dL, female 260 +/- 59 pg/dL
Lynx- No problem! Still trying to get a grasp on the forums, so feel free to edit anything you need to.

Here he is in the pen. So tiny compared to his brother, who, ironically, was always the smaller of the duo. It's like they somehow switched weights, and then he got sick.
Watermelon juice sounds like an interesting idea. He loves watermelon.
I also should mention, he has crusty eyes. I have taken him numerous times to the vet and he has no URI, so I'm beginning to think it's an immune response. Earlier in the year his eye was insanely watery, and turned out he had a sty that had to be popped, but now both are crusty, so I wipe them gently off. Today though, it was less crusty, so I wonder if his immune system is trying to latch onto the medication.
One of the hardest things I had to learn was to cherish my pigs with the time they had left vs. getting caught up in finding answers to every little thing. I was so caught up in keeping the first few alive that I can say that I didn't even want to think any day could be their last. Not saying this is what you are doing, but I think it can be very easy to despair at any signs of deterioration. Regardless of how long they are with us, the only thing they will remember is the love you have given them. So even if things are looking rough, remember to give them all the loving they can take.
Again, I'm crossing my fingers that he'll keep improving, but figured I'd share that wisdom in the meantime!
I do have a quick question, though. Like all medication, I know it's going to eventually (I hope not) put pressure on his kidneys. Do we know exactly when I should start testing him to make sure it's not? It hasn't been a month since the medication began, but I'm just wondering.
