Questions

Is it a finger-prick test?

No. A trained professional takes the sample from a vein, which a test this size needs.

Which ranges do you use?

Standard ranges for every marker. Where the evidence supports it, we also apply performance ranges, which are more useful for people who train.

What will my results tell me?

Where each marker was on the day you tested, with a doctor’s comments. They can show what’s worth following up, but they can’t explain every symptom.

When should I test again?

Your report will guide you. Test at the same time of day, prepared the same way, so the results compare fairly.
