Hi

It'd be good to see the reference ranges as it's hard to say for sure but at face value you look T3 toxic. Are you medicated for thyroid disease, what do you take and did you take your meds on the day of the blood draw? Were antibodies tested?

I did take my meds on the day I take 20 micro of Liothyronine twice a day and 125 micro of levo. free T3 range is 2.63 to 5.7 t4 is 9.01 to 19.05 not sure if this is what you require

I am treated for an under active thyroid

Hi there

Sorry to be the bearer of bad tidings but it's suggested we don't take our meds on the morning of the blood draw as they skew the results - your T4 and T3 are both out of range according to this test but because you took your meds it won't be accurate. T3 peaks in the blood two hours after taking (which isn't representative of your tissue levels or your normal levels). If you haven't had a panicked call from your surgery totally freaking out these results, partic your T3 levels (LOL) you will soon! You need to explain what you've done and explain that you are not hyper otherwise they will lower your medication. You could ideally do with doing the tests again and this time have your last dose of thyroid the day before. Also blood tests are only part of the story, more important to go by how you feel.
