Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.
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.
