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 Maximum clot strength amplitude. 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: Thromboelastography.resonance.adenosine diphosphate induced

What it does not mean

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

Key facts

Maximum clot strength amplitude [Length] in Blood by Thromboelastography.resonance.adenosine diphosphate induced
Maximum clot strength amplitude
The maximum clot strength in the presence of adenosine diphosphate, as measured by the amplitude of resonance of the blood meniscus as the blood sample clots. In this test, thrombin activity is blocked, and adenosine diphosphate (ADP) is used to activate platelets in order to measure the clot strength based on platelet activation by ADP, which result is used to determine the relative contribution of ADP-induced platelet activation [LOINC91128-9] to the overall clot strength [LOINC: 91125-5]. This term was created for, but is not limited in use to, the Submitter's test kit, the TEG6s PlateletMapping ADP Assay Cartridge for heparinized blood.
