Checking lactate dehydrogenase without a doctor

Order lactate dehydrogenase (LD/LDH/lactic-acid-dehydrogenase) blood testing online

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

I'd suggest ordering from DirectLabs because they have the cheapest price I know of ($29), and I've been happy with their service. You can also compare the other 6 lactate dehydrogenase test providers I've found.

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

Additional testing to determine isoenzymes

I won't pretend to understand when you'd want to test for particular isoenzymes (LD-1 through LD-5), but here's the providers I found for that:

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.
