1. Getting help

Email results@patientthread.com (or chris@patientthread.com). We reply within two working days. Please do not email us your results or ask us to interpret them; we cannot give medical advice and will direct you to your doctor.

2. Uploading

3. Reference ranges

The range printed by your laboratory always takes precedence and is stored with the result. Where a report prints no range, the app shows a typical UK adult range, clearly labelled, and notes that your lab's own range may differ. Results outside either range are marked "discuss with your doctor". The app never grades severity, calculates risk or suggests a diagnosis.

4. Plans and billing

The first report is free; typed-in results are always free. Plus is £4.99 a month and can be cancelled at any time from the Account screen, which opens the Stripe billing portal where you can also update your card and download invoices. Refunds under the 14-day cooling-off period: email us.

5. Your data

Download everything (JSON or CSV) or delete your account and all files from the Account screen. Deletion is immediate and permanent. See the privacy notice.

6. Requesting a test we do not list

We explain more than 400 tests. If a test on your report is not matched, it is kept under the name printed and still charted. Email the test name and we will add it to the catalogue, reviewed by our consultant physician author.
