LOINC Code 74021-7: Genetic risk algorithm

74021-7 is a LOINC code used to identify Genetic risk algorithm 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 Genetic risk algorithm. It is commonly used with the system or sample type ^Patient.

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 Genetic risk algorithm. It is commonly used with the system or sample type ^Patient.

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

What it does not mean

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

Key facts

  • Genetic risk algorithm
  • The genetic algorithm (e.g. BRCAPRO), or computer program, used to predict whether a patient has an inherited mutation in a given gene (e.g. BRCA1) and/or to determine their risk for developing a disease. The genetic algorithms are based on personal and family medical histories of a disease, such as breast and ovarian cancer. This term is based on, but not limited in use to, the Genetic Algorithm Used variable in the Family History section of the V2 VMR, based on the Family History Standard Implementation Guide (US Realm) 2012.
