Method
How we made this report
What the numbers count, what they leave out and how to read them.
Period and scope
The figures cover lab reports analysed between 2026-01-01 and 2026-06-30.
Adults only
Only reports from adults are counted. Reports known to belong to people under 18 are left out.
Counts only
The data holds counts of lab reports. It holds no names, e-mail addresses, account numbers, birth dates, file names or single values.
Numbers below 50 are not shown
Numbers below 50 are not shown, so no one can be recognised from a small group.
The lab's own reference ranges
Below and above mean outside the reference range printed on each lab report. Ranges differ between laboratories, countries, ages and sexes, so a result outside a range is not a diagnosis.
Not population figures
People chose to upload their reports, so the figures describe those reports. They are not prevalence figures for any population.
Duplicates and test accounts
Duplicate reports and test or internal accounts are removed before counting.
Not medical advice
Informational statistics, not a diagnosis or medical advice. Talk to a doctor about your own results.
