What should I know about MTHFR Labor?

MTHFR (methylenetetrahydrofolate reductase) is a gene involved in folate metabolism. Genetic tests for MTHFR variants (e.g., C677T, A1298C) are commonly offered by direct-to-consumer companies like MyBody-X as part of DNA tests. Key points: The clinical significance of these variants is debated. Many people carry one or two variants without any health issues. Evidence for supplementing with methylfolate or methylcobalamin in carriers is weak, mostly based on mechanistic or observational studies. Official guidelines do not recommend routine MTHFR screening. An 'MTHFR lab test' usually refers to a genetic test, not a blood test. MyBody-X can detect these variants, but results should not be taken as a medical diagnosis or directive. It is more important to ensure adequate folate intake through diet and consult a doctor if you have specific symptoms. Caveat: Overinterpretation can lead to unnecessary supplement spending.
