Frequently asked questions

Should I use this instead of my lab report?

No. Always use the reference interval printed on your own report. This tool shows common ranges for education only.

Why do ranges differ by sex?

Some tests (e.g. hemoglobin) have different normal ranges for males and females. Your lab may use different cutoffs.
