Know when a change is real
Results wobble from one draw to the next, even when nothing has changed. Lab scientists have measured how much for many tests, so when a result moves more than that, we say so.
Use the left and right arrow keys to read each result. Every result is also listed in the table below.
Down 41% since Jun 7, 2025. That's more than the usual test-to-test variation for LDL-C (about 24% either way), so it's likely a real change.
Medicines show as a shaded band on every chart, like Ruth’s statin. Results from different labs share one line, each with its own range. Open this chart
Try it with a number from your last report
Pick a test and type your result. Add your age and sex if you like, since many ranges depend on them.
No account, nothing saved. It’s the same reading every result in your record gets.
Type your result to see where it falls.
Nothing you type here leaves your browser.
A page to bring to the appointment
For a parent’s results or your own checkup. What’s outside the range, which changes are real and the questions worth asking, on one printed page in large, clear type.
Or send family or a clinician a private, read-only link. You pick how long it works, and you can turn it off.
Your results stay yours
No ads, and no tracking or analytics scripts on any page. We never sell or share your results. Your reports aren’t used to train AI, and the models we use are set to keep nothing. You can download everything, or delete everything, whenever you like.
Every range has a source you can open
Ranges come from the big reference labs and national guidelines, with links, and when labs disagree we say so. So far we’ve written up 578 tests from 2,566 sources, and 526 have had a second, independent check against them. 85 include U.S. population data. How we check them
