- People considering a medicine with established gene–drug guidance
- People with unusual response or toxicity where genetics may be relevant
- Prescribers choosing among specific evidence-supported options

TEST PASSPORT · REVIEWED JULY 2026
Pharmacogenomics
Use gene–drug evidence to inform selected prescriptions—not to generate a universal medication ranking.PGx can be actionable for specific gene–drug pairs. FDA-cleared consumer reports cover limited claims; results should be confirmed and interpreted with the prescriber and medication history.

HOW TO USE THIS PAGE
Decide whether this test deserves a place in your plan.
- 01Confirm the question
Be clear about what decision the result would change before ordering.
- 02Check fit and preparation
Review who it helps, who should pause and how to protect the quality of the signal.
- 03Plan the response
Know what you will do with a normal, abnormal or unclear result.
01 / WHO SHOULD TAKE IT
Fit the test to
the person.
Testing is useful when the result can change a real decision. These are educational selection criteria, not a diagnosis or personal order.- Stopping or changing a prescription from a colored report
- Assuming a ‘green’ drug will work or be side-effect free
02 / SIGNAL VS. STORY
What it tells you.
What it cannot.
01
Whether selected variants can affect metabolism, exposure or response
02
Which guideline-supported dosing considerations may apply
03
Whether confirmatory testing is needed
01
Most response is not explained by genetics alone
02
Panel coverage and evidence vary by vendor
03
Drug interactions, kidney/liver function, age and adherence often matter more
03 / MARKERS + RANGES
Read the panel
without chasing flags.
The report should show its own method, units and laboratory reference interval. Clinical decision thresholds may be different from a lab interval. We do not invent a universal “optimal” range where authoritative guidance does not support one.Use the laboratory unit and method, then interpret with symptoms, trend and the decision this marker can change.

MEN, WOMEN + LIFE-STAGE CONTEXT
The correct range is personal context—not pink versus blue numbers.
Where biology differs, we call it out. Clinical interpretation should also reflect organs present, hormone therapy, pregnancy, age, medications and health history.
Pregnancy, contraception and hormone therapies can change medication choice independent of PGx.
Organ function, other drugs and treatment goals remain essential; sex does not make a gene–drug result deterministic.
04 / PREPARATION
Protect the quality
of the signal.
The best assay cannot rescue the wrong timing, wrong specimen or wrong question. Follow the ordering clinician and laboratory instructions when they differ from this general guide.Include dose, duration, benefit, adverse effects and supplements.
Verify which variants and copy-number changes are actually assayed.
Arrange review before acting on the report.
REPEAT CADENCEUsually once because inherited DNA does not change; reinterpret as drug guidance evolves.
05 / AFTER THE RESULT
Turn the number
into a next step.
- 01
Confirm clinically important results when required
- 02
Use the result for the specific drug–gene pair only
- 03
Document the laboratory report in the medical record
DO NOT WAIT ON A CONSUMER TEST
Do not abruptly stop psychiatric, seizure, cardiac or anticoagulant medicines
Severe medication reactions need urgent clinical care
