01

Start with fit

Is this the right test for you?

The best test starts with a clear clinical question. These are common reasons a clinician or family may consider this test.

  • ✓Individuals experiencing adverse reactions to medications metabolized by CYP2D6.
  • ✓Patients prescribed medications known to be substrates of the CYP2D6 enzyme.
  • ✓Individuals with a family history of poor response or adverse reactions to specific drugs.
  • ✓Patients requiring dose adjustments for CYP2D6-metabolized medications.
  • ✓Individuals seeking personalized medication management based on genetic factors.

In plain language

What this test helps you understand

This test helps predict how an individual will metabolize drugs processed by the CYP2D6 enzyme. This information can guide medication selection and dosing to optimize therapeutic outcomes and minimize adverse drug reactions.
The Cytochrome P450 2D6 Genotyping test is a genetic analysis that looks at variations within the CYP2D6 gene. This gene provides instructions for making an enzyme crucial for breaking down many different medications. Understanding your specific CYP2D6 gene variations can help your doctor choose the most effective medication and dosage for you, potentially reducing side effects.

This test identifies the specific alleles (versions) of the CYP2D6 gene you carry. These variations can affect how quickly or slowly your body processes drugs like certain antidepressants, pain medications, and drugs for heart conditions. Knowing your metabolism type (e.g., poor, intermediate, extensive, or ultra-rapid metabolizer) allows for more informed treatment decisions.

This test is particularly useful for individuals starting new medications metabolized by CYP2D6, those experiencing side effects or lack of efficacy with current medications, or those with a family history related to drug response.
