MTHFR Genetic Test

The MTHFR Genetic Test looks for two common gene changes, C677T and A1298C, that affect how your body uses folate, a critical B vitamin. The MTHFR protein helps your body process folate and break down the amino acid homocysteine. Testing can reveal if these gene variants are contributing to elevated homocysteine levels in your blood. For individuals prescribed methotrexate, test results can also help providers determine a safer, more appropriate dosage. While medical experts generally prioritize homocysteine levels, knowing your MTHFR status can offer relevant personal health insights.
