What is a pharmacogenomic test?
Pharmacogenomics looks at how your genes affect the way your body responds to medicines. Small differences in your drug-metabolising genes can mean a standard dose is too strong, too weak, or more likely to cause side effects for you. A one-off test reads those genes so prescribing can be tailored to you - not the average patient.
We analyse the genes that matter most for drug response: the cytochrome P450 enzymes (CYP2D6, CYP2C19, CYP2C9, CYP3A4/5), the drug transporter SLCO1B1, and drug targets such as VKORC1 for warfarin. Around 5–10% of people of European ancestry are CYP2D6 “poor metabolisers”, for example - your report places you in one of four clear categories (poor, intermediate, normal, or rapid/ultra-rapid).
What it covers - 112 medications, 14 therapy areas
Your report spans the medicines where genetics most affects safety and effectiveness:
- Mental health - 25 drugs (SSRIs, SNRIs, tricyclics, antipsychotics)
- Pain relief - 12 drugs (codeine, tramadol, oxycodone)
- Heart - 9 drugs (warfarin, clopidogrel, carvedilol)
- Cholesterol - 7 statins
- Cancer - 11 drugs (tamoxifen, irinotecan, capecitabine)
- Infection - 12 drugs (antiretrovirals, antivirals)
- And more - digestive, immune, nervous system, diabetes, bone & joint, ADHD, chest
How it works
- Talk to a clinician - start with a free 30-minute consultation with a GP to confirm the test is right for you.
- Consent & collect - complete your online consent, then collect your sample at home with a simple cheek swab. No clinic visit, no fasting.
- Results & follow-up - your report is reviewed by a GP and shared securely, with a complimentary video appointment to talk it through if needed.
Why Jeen
- Same lab and technology as major UK reseller programmes - analysed at Eurofins UK on Illumina pharmacogenomic arrays (CE-IVD, ISO 15189/17025/13485, CQC-registered).
- No pre-test delay - your kit ships the day you order.
- A lifetime-valid report - your genome doesn't change, so you can reuse it for any future prescription.
- Independent and private - results are never shared with UK health insurers, and your sample is destroyed after your report is delivered.
- No fasting, and no need to stop your current medication.
