Methylmalonic acid (urine)
Test performed as part of urine organic acid analysis. Methylmalonic acid (MMA) is a metabolite which can be elevated in a number of inherited metabolic disorders (e.g. methyl malonic aciduria, defects of cobalamin metabolism, SUCLA 2 deficiency).
|Additional Information||Semi quantitation is available for patients with known inherited metabolic disorders.|
