PROCEDURE FOR DOING THE MMA TEST FOR B12 STATUS
(U.S. folks only)
(Norman Labs is no longer doing MMA testing)

You can do the MMA test for B12 status this way:

If you're doing any other tests with LabCorp labs through Life Extension (like the D or thyroid tests), you do this MMA blood test while at the lab for your blood draw. Or you could go to a LabCorp lab just to do the MMA blood test.

Life Extension Foundation does the D and thyroid tests too. I have quite a number of clients who use them, and they are very pleased. You order the tests online, pay for them online, print out a page they email you, and take it to a local LabCorp lab to get the blood tests done, then LEF will email you the results, and you'd email them to me (if you're counseling with me).

After purchasing the test(s) from Life Extension, you can use this website to locate your nearest LabCorp lab. They close at 3pm. You can make an appointment (which is quicker than just walking in).

All fees are paid directly to Life Extension. I have no affiliation with Life Extension or LabCorp.

NOTE: The urine sample for the at-home uMMA test should not be clear; it must have some color. The "first morning" sample should be concentrated enough to have some color. If it doesn't, the day before the test, cut back on fluid intake (water and coconut water), and no watermelon either.
