Profile Information A profile is a group of laboratory tests that are ordered and performed together under a single Mayo Test ID. Profile information lists the test performed, inclusive of the test fee, when a profile is ordered and includes reporting names and individual availability.
| Test ID | Reporting Name | Available Separately | Always Performed |
|---|---|---|---|
| STSHC | TSH, Sensitive, S | Yes, (order STSH) | Yes |
Reflex Tests Lists test(s) that may or may not be performed, at an additional charge, depending on the result and interpretation of the initial test(s)

Testing Algorithm Delineates situation(s) 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 T3 is performed at an additional charge.
If TSH is >5.0 mIU/L, then FT4 and thyroperoxidase antibodies are performed at an additional charge.
