LOINC Code 57838-5: Coagulation (PPP) [Time]

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. 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: Both
• Method: Dilute Russell viper venom induced.excess phospholipid

What it does not mean

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

Key facts

• dRVVT W excess phospholipid (LA confirm)
• Coagulation
• If the coagulation defect corrects with excess phospholipid, it confirms the likely presence of phospholipid antibodies and the LA syndrome. Platelets, bilayer and hexagonal phospholipids are variously used as the source of excess phospholipids and this term covers them all. The use of one term for these variations reduces mapping work for practices that import laboratory results, but laboratories that use hexagonal phospholipids and think it important to distinguish their source can use 75883-9 instead of this term.
