When I learned how easy it is to get your vitamin D, thyroid, cholesterol, and inflammation tested, I was immediately hooked. It was much easier to make progress on my health problems once I had an objective way to see what was and wasn't working. So I made this site to cobble together my notes on how to order any kind of test you can think of (both bloodwork and at-home kits), primarily for when I hassle people about checking their bloodwork.

How does the process work?

Generally, you place an order from a consumer-oriented web site that then sends you a form to take to a local blood-draw center. They'll take a blood sample and you'll usually receive the results over e-mail within a few days. Often the company will offer some kind of consultation based on the results. Here's the full details of the process.

Why do I blood test?

Buying my own bloodwork lets me:

What tests do I get?

My favorite hobbies in life are feeling good and not dying. So I mainly monitor:

Over the years I've also been known to get individual tests to check hypotheses, like ferritin (for iron status), ceruloplasmin (for copper status), vitamin D (for managing my avoidance of that pesky "outdoors" thing), and TSH / T3 / T4 / reverse T3 (for thyroid function).

And if I ever overcome my guilt on spending a good $900+ on bloodwork over the years, I'd be curious to test some of the more expensive things like selenium, glutathione, and organic acids.

I also have a page on resources for tracking, understanding, and influencing your bloodwork.

LabEspy and FindLabTest have more-comprehensive price comparisons if you're hunting for a test or provider I don't have.

About me

I don't have any health/medical background, I'm just a nerd who had a lot of seemingly-unrelated health problems (struggles with endurance, body composition, insomnia, and chronic fatigue) that I finally started making progress on, with blood testing being my most useful tool. Hence having a web site where I obsess over testing :)

You might be interested in my YouTube channel about feeling better using biomarkers. As a sample, my most-recent video is a simple thyroid function test you can do at home:

You might be vaguely familiar with me if you're a fan of the ideas of Ray Peat: I maintain a directory of Peat-related sites, a podcast feed for his interviews, and a page for searching his content. Testing Peat's ideas with before-and-after blood tests was what originally got me intrigued by his ideas: in just couple months my high CRP dropped 86%, my high LDL dropped 37%, my triglycerides dropped 83%, and my prolactin dropped 58%. And more importantly I could eat, sleep, and exercise like a functioning human being.


Let me know if I've missed any tests you're interested in, or if you just want to reminisce about how good The Office was.
