No more trial and error
The right medication,
the first time.
Your DNA shapes how your body responds to medication. One Tenacity's PGx test reveals which drugs work for you — helping you and your doctor choose safely, confidently, and without guesswork.
Our laboratory is accredited by the CAP and certified under CLIA, ensuring the highest standards in clinical genomic testing.
The Science Behind the Test
What is pharmacogenomics?
Pharmacogenomics — or PGx — is the study of how your genes affect the way your body processes medication. Small, inherited variations in your DNA can mean that a drug works differently for you than it does for the average person.
A One Tenacity PGx test identifies these variations so that you and your doctor can make informed decisions — choosing drugs and doses matched to your biology, not statistical averages. It's a test you take once. The results inform every medication decision for the rest of your life.
Prevent Adverse Reactions
Gene variants can make standard doses dangerous for certain patients. Your PGx profile flags these risks before a drug is ever prescribed, not after a reaction occurs.
Personalize Your Dose
Some people metabolize medication too quickly and see no benefit at standard doses. Others metabolize too slowly and risk toxicity. Knowing where you fall changes everything.
Inform Your Care Team
Your shareable PGx report gives prescribers actionable, evidence-based guidance — personalized to your genome, not statistical averages. One report, useful for every medication decision you'll ever make.
The Process
Four steps to clarity.
Order Online
Purchase your kit from our website. It ships discreetly and directly to your door anywhere in Canada within a few business days.
Collect Your Sample
A simple cheek swab at home — no needles, no clinic visit, no fasting required. Detailed instructions are included. Takes under five minutes.
Lab Analysis
Mail your sample using the prepaid envelope included with your kit. Our certified laboratory analyzes your DNA profile. Results are typically ready in 10–14 business days.
Access Your Report
Log in to your secure portal to view your personalized PGx report. Share it directly with any member of your healthcare team — a one-time test, a lifetime of insight.
PGx testing is a diagnostic tool intended to support — not replace — clinical judgment. Always discuss results with a qualified healthcare provider before making any changes to your medications.
Sample Collection
How to use your kit.
Open Your Kit
Confirm it contains the swab, RapiDri pouch, and barcode label.
Collect Your Sample
Rub the swab firmly against the inside of both cheeks for 30 seconds each.
Insert and Seal
Place the swab head-first into the RapiDri pouch. Fold over the dotted fold line and seal with the barcode sticker. If you ordered multiple kits, apply the included kit-code sticker and keep track of which patient sample matches which kit code.
Drop It in the Mail
Place the sealed pouch(es) into the pre-paid return envelope and drop it off in any mailbox. That's it!
