FRT4C | T4 (Thyroxine), Free, S | Yes, (order FRT4) | No |
TPOC | Thyroperoxidase Ab, S | Yes, (order TPO) | No |
T3C | T3 (Triiodothyronine), Total, S | Yes, (order T3) | No |
If thyroid-stimulating hormone (TSH) is <0.3 mIU/L, then free T4 (FT4) is performed at an additional charge.
If FT4 is normal and the TSH is <0.1 mIU/L, then triiodothyronine (T3) is performed at an additional charge.
If TSH is >4.2 mIU/L, then FT4 and thyroperoxidase antibodies are performed at an additional charge.
