Re: Best time of day for blood draw??

[Guest guest]

I have read both opinions - that one should take your meds as usual

and also that one should get the blood drawn before taking your

meds. Your free levels will tend to be higher and your TSH lower in

the afternoon after taking your meds. Because I have problems

getting a high enough thyroid dosage from doctors, I always have my

blood drawn in the morning before taking any thyroid medication. It

is also a good idea to be consistent and have blood drawn at about

the same time so that you can compare your test results better. If

your goal is get more thyroid medication, I personally would advise

that you wait until morning and have it drawn before taking your

medication. But if you are worried about spikes or going over your

range, then do take your meds. I am no expert, but this is my

understanding.

Your doctor sounds like a really good one. Most doctors don't see

that many symptoms are thyroid related. They also like to rely on

TSH only and my TSH has to be suppressed to almost zero in order for

my FT3 and FT4 to be correct.

Good luck to you,

This is great, Ruth!

Best time of day for blood draw??

I went to my doctor for a follow-up on my adrenals. I mentioned that I was surprised that the Free T4 and T3 were not measured. She said "but the TSH" and I said, but I still have symptoms. (To her credit, I did not go in for thyroid, and it was "understood" that my thyroid was ok... there are so many things to look at.) And my TSH is below 1. So then she said, well then your body may not be converting correctly. She wrote a script for me to get the FT4 and FT3 and TSH. So I was very relieved. I even just said "and my sinuses are really still chronic and I heard that that is related to low thyroid" and she said... "it is."

If I go to the lab this afternoon, will I get a "good" reading? I take my thyroid in the morning.
