I had my thyroid bloods done on Friday 13th June - rang GP surgery last week and only TSH came back which was 1.04. My Ferritin was 91.1. No T4 result was there.
Have rang again today and still no T4 result. Have rang the hospital blood laboratory and spoke to a nice lady who informed me that T4 is only tested on special criteria. When asking what that criteria was, she said its when the GP requests it. I said the box was ticked on the form for T4.
I said my TSH was within normal limits (or so the GP said). She said that could possibly be why the T4 was not tested. She said she will have a look through the tests and send them to the GP if she finds a result for T4.
My question is, is this correct do they only do T4 if the TSH is not normal.
