Should you get an MTHFR gene test before pregnancy?

For most women, no. Major medical organizations, including the American College of Medical Genetics and Genomics, recommend against routine MTHFR testing because the results rarely change what your provider would recommend anyway. The exception is if you have a personal or family history your provider flags as relevant, such as a previous neural tube defect pregnancy or unexplained high homocysteine.

Always consult your healthcare provider before starting any new supplement, especially during pregnancy, breastfeeding, or while managing a medical condition.

Why MTHFR testing is suddenly everywhere

MTHFR variants are common: Cleveland Clinic notes that experts estimate up to half of people have a change to at least one MTHFR gene. Social platforms have picked up on this and turned MTHFR testing into a preconception "must-do," often alongside claims linking the variant to miscarriage, infertility, or a long list of unrelated health conditions.

The biology behind the trend is real. The gene affects an enzyme involved in folate metabolism. What often gets lost is what that actually means for your care.

What the guidelines actually say

A 2013 practice guideline from the American College of Medical Genetics and Genomics, published in Genetics in Medicine, states that MTHFR polymorphism testing has minimal clinical utility and should not be ordered as part of routine evaluation for thrombophilia or recurrent pregnancy loss. Cleveland Clinic physicians writing on the topic put it directly, describing "the lack of evidence for association with thrombotic risk," and recommend clinicians instead focus on modifiable risk factors.

According to MedlinePlus, a resource maintained by the National Library of Medicine, testing checks for two common gene variants, but having one does not tell your provider anything that changes your prenatal folate recommendation, which is the same for everyone: get enough folate, in whichever form works for you.

What actually changes your care, if anything

• A personal history of a neural tube defect-affected pregnancy
• A family history your provider considers relevant
• Confirmed high homocysteine on bloodwork, evaluated for other causes
• A known clotting disorder being worked up for unrelated reasons

Outside of these situations, most guidelines point toward the same recommendation regardless of test result: take adequate folate, ideally in a form your body can use directly.

What to do instead of testing

Rather than ordering a test, most providers will simply recommend a prenatal with methylated folate (5-MTHF), since it supports healthy fetal neural tube development without depending on the enzyme conversion step MTHFR variants can slow down.† This gets you the same practical benefit as testing, without the cost or the anxiety of waiting on results.

Total Prenatal is formulated with methylated folate rather than folic acid. You can read more about our prenatal with methylated folate and gentle iron. For women still in the preconception window, our fertility gummies with methylated folate and myo-inositol take the same approach as part of a broader nutrient profile.

Frequently asked questions

Does insurance cover MTHFR testing?

Coverage varies, and since major guidelines recommend against routine testing, many providers will not order it without a specific clinical reason. Ask your provider directly about your situation.

If I already know I have an MTHFR variant, does that change my prenatal choice?

It may make methylated folate a more clearly preferred choice for you personally, but the underlying recommendation, adequate folate intake, is the same regardless of variant status.

Can an MTHFR variant cause miscarriage?

Major guidelines state there is no strong, consistent evidence that MTHFR variants directly cause recurrent pregnancy loss, and routine testing is not recommended as part of a miscarriage evaluation.

Is MTHFR testing the same as standard prenatal genetic carrier screening?

No. Carrier screening panels test for different conditions, and current joint guidance suggests MTHFR is a poor candidate for inclusion on those panels given its high prevalence and low predictive value.

Do I need a doctor's order to get an MTHFR test?

Direct-to-consumer genetic tests exist, but any result should be discussed with a healthcare provider rather than interpreted alone, especially if it changes how you feel about your pregnancy.

What should I focus on instead of testing?

Talk with your provider about your folate intake and the form of folate in your prenatal, since that addresses the practical concern most women are actually trying to solve.
