Methylene Tetrahydrofolate Reductase (MTHFR) Test – Short Description:

The MTHFR test measures the activity of the MTHFR enzyme, which plays a key role in processing folate (vitamin B9) and converting it into its active form. Variants in the MTHFR gene can affect this enzyme’s function and lead to elevated levels of homocysteine in the blood, which is associated with an increased risk of cardiovascular disease, blood clots, and certain pregnancy complications. This test is often used to assess genetic risk factors for these conditions, especially when there are concerns about folate metabolism or unexplained health issues.
