LOINC Code 96695-2: Rate of fibrin formation (Bld) [Units/Time]

96695-2 is a LOINC code used to identify Rate of fibrin formation (Bld) [Units/Time] 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 Rate of fibrin formation. It is commonly used with the system or sample type Bld.

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 Rate of fibrin formation. 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: Microviscometry.diatomaceous earth and clay induced

What it does not mean

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

Key facts

  • Rate of fibrin formation [Units] in Blood by Microviscometry.diatomaceous earth and clay induced
  • Rate of fibrin formation
  • Microviscometer analyzers used clinically for coagulation assays commonly report a unit for clot formation that monotonically increases with increasing viscosity but is not a standard viscosity unit such as centipoise. The clot unit produced by these assays has a long historical precedent. It is considered a measure of viscosity of a liquid prior to clot formation and the viscous component of a viscoelastic gel after clot formation, albeit reported on a continuous scale.
