LOINC Code 91128-9: Clot strength Thromboelastography.platelet adenosine diphosphate receptor inhibited (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 strength. 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.platelet adenosine diphosphate receptor inhibited

What it does not mean

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

Key facts

• Clot strength [Length fraction] in Blood by Thromboelastography.platelet adenosine diphosphate receptor inhibited
• Clot strength
• Calculation of percentage of clot strength that is lost due to inhibition of adenosine diphosphate (ADP)-induced platelet aggregation. This is calculated based on measurements of the patient's maximum clot strength and clot strength due to ADP-induced platelet aggregation, via methods such as thrombelastography or resonance thromboelastography. It is used to guide anti-platelet therapy decisions.
