LOINC Code 85819-1: Clot firmness reduction 60 Min p max clot amplitude + heparinase TEG (Bld) [Length fraction]

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 Clot firmness reduction^60M after maximum clot amplitude after addition of heparinase. It is commonly used with the system or sample type Bld.

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: Thromboelastography

What it does not mean

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

Key facts

• Clot firmness reduction [Length fraction] in Blood by Thromboelastography --60 min p max clot amplitude + heparinase
• Clot firmness reduction^60M after maximum clot amplitude after addition of heparinase
• In this assay, the reduction of clot firmness (i.e., clot lysis), is measured 60 minutes after maximum clot amplitude is reached. Heparinase is added prior to starting the assay in order to eliminate interference by any heparin that is in the patient's sample.
