That is why the FDA reasons sound just like propaganda.

It seems to me that learning about MTHFR and then seeing your doctor would be a good idea. Have the test redone then, (the doctor would balk less than if you asked out of the blue), and then it would be in your record. I do think the MTHFR genetic issue will someday be linked to cancer etc. Better to know your status now and use methylfolate and methylB12 to become healthier and less at risk. (methylation is involved in cancer protection too but less is known at this time clinically about it).

Best to learn you have hemochromatosis so you can GO TO YOUR
DOCTOR for treatment and evaluation for organ damage etc. (BEFORE YOU DIE or end up on dialysis.)

As far as accuracy? Well Quest has TWICE sent out inaccurate Vit D test results over 1yr in the first case and MONTHS in the second case. Labs that do tests for medical places are known for errors etc. That is why doctors RETEST often!

The FDA is being pressured by some entity to stop these tests IMO.
