What does this LOINC code represent?

This LOINC code identifies a lab observation, measurement, question, or clinical concept in a standardized format.

Is this enough to understand my test result?

No. The code identifies the test or observation, but the interpretation depends on the actual result, reference range, and clinical context.

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 CYP3A4 gene targeted mutation analysis. 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: Both
Method: Molgen

What it does not mean

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

Key facts

CYP3A4 gene targeted mutation analysis in Blood or Tissue by Molecular genetics method

CYP3A4 gene targeted mutation analysis

CYP3A4 gene mutation analysis for targeted polymorphisms (SNPs) is performed to determine a patient's allellic genotype and overall drug metabolism phenotype (ultrarapid, extenisive, intermediate, or poor metabolizer). This term is used to report the patient's allelic genotype, drug metabolism phenotype and overall interpretation in a single narrative report. The submitter's lab currently (as of 2013) tests for the following CYP3A4 alleles*1B, *1G, *3, *4, *5, *6, *10, *12, *17, *18, *20 and *22. Selection is based on current literature. For a complete list of alleles and more information on CYP3A4, see http://www.cypalleles.ki.se/cyp3a4.htm.
