Pharmacogenomics (PGx)
Pharmacogenomics is the study of how your DNA changes the way you process medications. Variants in liver enzymes — chiefly the CYP450 family — can make you metabolize a drug too fast to benefit or too slowly to tolerate. A one-time PGx test maps your metabolizer status so prescriptions start from your biology instead of trial-and-error.
How do genes change drug response?
Most medications are activated or cleared by liver enzymes. Common variants in genes like CYP2D6, CYP2C19 and CYP3A4 speed those enzymes up or slow them down. The same standard dose can be sub-therapeutic in an ultrarapid metabolizer and toxic in a poor metabolizer — same drug, same dose, opposite outcomes.
Which medications does PGx inform?
Well-established gene-drug pairs include antidepressants (SSRIs via CYP2C19/2D6), clopidogrel (CYP2C19), statins (SLCO1B1 — myopathy risk), certain pain medications (CYP2D6 and codeine), and PPIs. The CPIC consortium maintains peer-reviewed dosing guidelines for each validated pair.
CPIC (Clinical Pharmacogenetics Implementation Consortium) guidelines are the clinical standard we follow — we don't act on gene-drug pairs without guideline support.
Who benefits most from PGx testing?
Anyone starting an antidepressant, managing multiple prescriptions, with a personal or family history of unusual drug reactions, or beginning long-term therapies like statins. Because your genome doesn't change, one test informs every prescribing decision for the rest of your life.
How does Integrated Wellness use PGx results?
Your metabolizer profile lives in your Digital Twin alongside labs and biometrics. When your physician considers a medication, the Matrix Engine surfaces any relevant gene-drug interaction and CPIC guidance before the prescription is written — turning trial-and-error into informed first choices.
What are the limits of PGx?
Genes are one input, not the whole story — kidney and liver function, drug interactions, age and body composition all shape response. PGx removes a major source of guesswork; it doesn't replace clinical judgment or follow-up monitoring.

Is PGx testing a one-time thing?
Yes — your genotype is stable for life. What evolves is the guideline library, so stored results get re-interpreted as new gene-drug evidence is validated.
Will it tell me which antidepressant will work?
It narrows the field — identifying drugs you're likely to clear abnormally — rather than naming a guaranteed winner. That alone meaningfully reduces the failed-trial cycle.
Is my genetic data secure?
PGx results are stored in your encrypted clinical record under the same HIPAA-grade controls as every lab — never sold, never shared without your authorization.
Does it require a blood draw?
Usually just a cheek swab or saliva sample, collected at home and processed by a certified clinical lab.
