Checking serotonin without a doctor

Order serotonin blood testing online

In the majority of US states you can order serotonin testing online and have the blood drawn at a local blood draw center (see my general overview of the process).

I've always done with whole-blood serotonin testing because of the vague impression it's more actionable than serum. See the next section if you'd prefer serum options.

I'd suggest ordering from Life Extension because they have the cheapest price I know of ($66), and I've been happy with their service.

I haven't found any other providers. Let me know in the comments if you know of any other sources.

Take a look at my state-specific issues page if you're in AZ, MD, NJ, NY or RI.

Sources for serum testing

If you'd prefer serum testing, here's the sources I've found:

Understanding the results

The American Association for Clinical Chemistry has helpful pages for understanding the test and answering common questions.

If you're interested in self-testing as I am, check out my Facebook or Twitter account where I post interesting self-testing news and get a little too excited about blood test sales.


Please leave a comment if you see a way to improve this page or if you have any questions. Keep in mind that I know little about the medical side of bloodwork, I just enjoy making sites with lists of things.
