I had my father take a Blue Horizon Thyroid test, results were:
TSH 0.86 0.27 - 4.20 IU/L
T4 Total H 159.5 64.5 - 142.0 nmol/L
Free T4 16.34 12 - 22 pmol/L
Free T3 4.83 3.1 - 6.8 pmol/L
Anti-Thyroidperoxidase abs H 74.5 <34 kIU/L
Anti-Thyroglobulin Abs 52.4 <115 kU/L
Obviously worried about the Anti-Thyroidperoxidase result, but as he has prostate cancer he's been on hormone therapy, came off about six months ago. I'm wondering if that might skew the result.
Ordered him a celiac test in case gluten is causing him problems.
