LOINC Code 75884-7: aPTT.lupus sensitive screen to confirm Coag (PPP) [Ratio]

75884-7 is a LOINC code used to identify aPTT.lupus sensitive screen to confirm Coag (PPP) [Ratio] in laboratory and clinical observation data. You may see this code in lab systems, lab reports, EHR exports, interoperability feeds, or other structured clinical data exchanges. LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component Coagulation surface induced.lupus sensitive/Coagulation surface induced.lupus sensitive.excess phospholipid. It is commonly used with the system or sample type PPP.

What is this code?

LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component Coagulation surface induced.lupus sensitive/Coagulation surface induced.lupus sensitive.excess phospholipid. It is commonly used with the system or sample type PPP.

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: Observation
  • Method: Coag

What it does not mean

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