Toenail fungus quiz
Do I have toenail fungus?
Have a look at the nail you're wondering about, then answer each question as best you can. If you're not sure, that's an answer too.
This quiz is general information, not a diagnosis.
Important: this quiz is not a diagnosis
It can only tell you whether your answers match common signs of toenail fungus. Other conditions, such as nail psoriasis and nail injury (trauma), can look very similar, which is exactly why testing the nail helps. See a doctor urgently if you have diabetes and a wound, sore or blister on your foot, or if you have pain, redness, warmth, swelling or pus around the nail, or any other signs of infection.
Frequently asked questions
Quick answers about the quiz and what to do next.
Is this toenail fungus quiz a diagnosis?
No. It is general information based on common signs and risk factors. Only a healthcare provider can diagnose a nail condition, and a lab test is often used to confirm fungus.
How accurate is the quiz?
It can only estimate how closely your answers match common patterns of toenail fungus. Nail psoriasis, injury and other conditions can look similar, so a matching score does not prove you have fungus.
What should I do after I finish the quiz?
Use the next steps on your result screen. If your nails look thick, discoloured or crumbly, consider confirming with a mail-in qPCR nail test and share the report with a pharmacist, doctor, podiatrist or other healthcare provider.
Does the quiz store my answers?
Your answers stay on your device for the quiz session. The quiz is designed to run in your browser without creating an account.
Can I order a test kit after the quiz?
Yes. If you want to know whether fungal DNA is present, you can order the at-home mail-in kit. Your sample is analysed with qPCR and reviewed by a licensed Canadian podiatrist.
Ready to stop guessing?
Clip your nail at home and mail it back. Your sample is analysed with qPCR DNA testing and reviewed by a licensed Canadian podiatrist. Results in 4–14 days after your sample arrives.
