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 stiffness reduction due to fibrinolysis. 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: Observation
  • Method: Calculated

What it does not mean

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

Key facts

  • Clot stiffness reduction percent due to fibrinolysis in Blood by calculation
  • Clot stiffness reduction due to fibrinolysis
  • The reduction of clot stiffness due to the effects of fibrinolysis, calculated based on the difference in clot stiffness in the absence and presence of an antifibrinolytic agent such as tranexamic acid.
