I've been looking for a posting with results similar to mine. Does anyone have an idea why my Free T3 (in the attached image) is on the low side but Free T4 appears normal?
Also, the following are my results from 3 months prior, Free T3 is higher:
TSH H 5.00 (0.27 - 4.20 mIU/L)
T4 Total 75.9 (64.5 - 142.0 nmol/L)
Free T4 16.53 (12 - 22 pmol/L)
Free T3 5.30 (3.1 - 6.8 pmol/L)
Anti-Thyroidperoxidase abs 7.2 (<34 kIU/L)
Anti-Thyroglobulin Abs 19.1 (<115 kU/L)
I plan on getting my thyroid retested, but I am curious if anyone might explain the erratic T3 levels.
