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.

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: Order
Panel type: Panel
Method: Molgen

What it does not mean

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

Key facts

Warfarin response genotype panel - Blood or Tissue by Molecular genetics method

Warfarin response genotype panel

This panel contains genotype results for warfarin dosing. As of 2019, CYP2C9, VKORC1, CYP4F2, and rs12777823 genotypes are used when available to help determine a patient's initial therapeutic warfarin dose. VKORC1 and CYP2C9 genotypes are the most important genetic determinants of warfarin dosing. Additionally, a genetic variation in the CYP4F2 gene, CYP4F2*3, as well as a variant near the CYP2C gene cluster, rs12777823, have been associated with influencing warfarin therapy.[NCBI BooksNBK84174] This panel is based on, but not limited in use to, the 2017 Update of the Clinical Pharmacogenetics Implementation Consortium (CPIC) Guideline for Pharmacogenetics-Guided Warfarin Dosing, which provides warfarin dosing recommendations for adults with and without African ancestry, and also for pediatric patients.[https://cpicpgx.org/content/guideline/publication/warfarin/2017/warfarin.pdf]
