What This Test Measures

Combined B12 and folate measurement; complete assessment of these related vitamins.

Preparation

No fasting required
No fasting required. If supplementing B12 (oral or injection), discuss timing with your provider — recent supplementation can affect results. MMA and homocysteine are more sensitive markers of functional B12 status.
💬 Patient Community Notes

Serum B12: unreliable if supplementing — the B12 Society recommends 4 months free of all B12 supplements AND fortified foods for true baseline. MMA and homocysteine are more reliable markers of functional B12 status during supplementation. For serum folate: fast 8+ hours (eating falsely elevates results). RBC folate is preferred for long-term status. The STTM community targets B12 in the upper quarter of range and folate in the top third. For MTHFR patients, both should be monitored closely.
