No, you don't have to do an official OFA panel. But it does help to do that anyways so that results are in the public database. Also if your dog is from a responsible breeder that is good info for them to know, the health testing results from littermates and relatives of breeding prospects.
Dr. Dodds is great for doing thyroids. But I believe if you have the OFA panel done, it's not done at her lab anyways, but at the other Antech lab on the other side of the country. And OFA doesn't look at her interpretations, they just look at the numbers from the test.
You can also ask your vet what lab they use for sending out thyroid tests. The important thing is that you get a full panel done, not the "in house" tests that only look at a couple values. You need at least T4, free T4, TgAA, and TSH. Whatever lab you use, all you have to do is fax over a copy of the test scores to Dr. Dodds and she will be happy to interpret them "Basenji style" for free. Sighthounds traditionally have slightly different normal ranges than what the lab machines use.
Also I like to recommend people use an accredited lab that is closest to them, if they aren't near Antech or MSU. I have seen people get equivical or odd test results when the blood had to be shipped out of state. I am not sure of the validity behind this, but length of time that the blood is sitting around may affect test results. Luckily I didn't have that problem, I only lived 40 minutes from MSU which has one of the top 2 thyroid labs in the country. lol
Kudos to you for testing! Hope everything comes back with great results!
