Most doctors either don’t work with or are entirely unaware of MTHFR polymorphisms. Some specialists, including obstetricians, gynecologists, and fertility specialists will test for and consider MTHFR in the context of pregnancy. Some cardiologists or hematologists will test for MTHFR as well – especially after an abnormal blood clotting incident. The majority of doctors and practitioners who work with the day-to-day symptoms of MTHFR are naturopathic doctors, DABCI chiropractors, integrative doctors, or health care specialists. The best people to work with for MTHFR are people who have MTHFR as an area of focus.
