Question

Quizplus · Accepted Answer

RBC folate level is a better indicator of folate status over the past month because it reflects the amount of folate stored in red blood cells, which have a lifespan of around 120 days. Folate level only measures recent intake and may not reflect long-term status. Vitamin B₁₂ level and MMA are tests used to determine functional deficiencies of folate, not overall status.
