LOINC Code 73682-7: CYP2D6 gene allele 1 Molgen Nom (Bld/Tiss)

73682-7 is a LOINC code used to identify CYP2D6 gene allele 1 Molgen Nom (Bld/Tiss) 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 CYP2D6 gene allele 1. It is commonly used with the system or sample type Bld/Tiss.

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 CYP2D6 gene allele 1. It is commonly used with the system or sample type Bld/Tiss.

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: Molgen

What it does not mean

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

Key facts

CYP2D6 gene allele 1 [Identifier] in Blood or Tissue by Molecular genetics method Nominal
CYP2D6 gene allele 1
This code is used to report one of the patient's CYP2D6 gene alleles based on results from variants (SNPs) tested. See LOINC 73681-9 for reporting the patient's other CYP2D6 allele. The example answers provided with this code are a small representative of the CYP2D6 alleles. For a complete list, see the The Human Cytochrome P450 (CYP) Allele Nomenclature Database (http//www.cypalleles.ki.se).
