Your draw is coming up — high-dose biotin can interfere with thyroid blood tests, so can make results look falsely abnormal.

Snap a photo of your lab printout or upload the PDF, and we'll pull the values in. Or type them yourself.
Dose changes sit on the same timeline as your results and symptoms, so you can see what happened after each one.
Labs disagree on units, reference ranges, and which hormones they test. We convert units, store each lab's own ranges, and log the panel your doctor ordered.
Enter past results with the dates they were taken, and see them on one timeline with your recent ones.
Reference ranges differ between laboratories. Haloscan shows the range printed on your own report, and links to the source of every default it seeds.

My mom has Hashimoto's. For six years she was told her labs were normal while she kept getting worse. She tracked everything herself — labs, dose changes, symptoms — in spreadsheets her doctor never looked at.
So I built her something better. Every result on one timeline. Every dose change marked. Symptoms underneath, morning and evening. One page at the front with three questions drawn from her own data.
Her next appointment wasn't a breakthrough. But her doctor noticed a pattern he'd missed for years, and adjusted her prescription.
I made the same report for anyone who asked, for free, until I couldn't keep up.
Haloscan is that report, built properly.
