LOINC Code 79963-5: Aortic valve Maximum gradient during systole [Pressure Difference] by US.doppler+Calculated by simplified Bernoulli

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 Gradient.systole.max. It is commonly used with the system or sample type Aortic valve.

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: US.doppler+Calculated by simplified Bernoulli

What it does not mean

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