Sorry another blood test result request

Hello all, brief history - diagnosed last year with thyroid nodules both sides. Waiting on another scan appointment to see if they have got bigger, possible surgery if so. Recent blood test results: serum TSH 1.7. (0.4 - 5.0). Serum free T4 11 (9-19) having hypo symptoms but apparently blood test normal ? Is this test sufficient for diagnosis and does Hasimotos need to be tested for seperately. Thanks in anticipation

Hi Eleanor, Your TSH is above the level of just over/just under 1.0 most people are comfortable with and your FT4 is low in range which means you will almost certainly have a low level of the active hormone T3. Unfortunately a clinical diagnosis of hypothyroidism is unlikely to be made until your TSH is >5.0.

Thyroid Peroxidase antibody (TPOab) is the test commonly used to test for autoimmune thyroid disease (Hashimoto's) which eventually causes hypothyroidism.


Hi and thanks for taking the time to reply. I'm having a hard time trying to get doctors to do blood tests and like many others I have noted just don't get taken seriously. Guess I will just have to wait until next scan. Thanks again
