When is it used?

  • Used in lab systems, EHRs, and clinical data exchange.
  • May identify a test, observation, survey item, or clinical document request rather than a diagnosis.
  • Status: ACTIVE
  • Order vs observation: Both
  • Method: Detection limit <= 0.005 mIU/L

What it does not mean

  • The code identifies the observation or test, not the actual result.

Key facts

  • Thyrotropin [Units/volume] in Serum or Plasma by Detection limit <= 0.005 mIU/L
  • Thyrotropin
  • This is a so called 3rd generation test and "detection limit" given is the analytic detection limit (Functional detection limit would be higher)
