The same assay can be applied to serum, EDTA-plasma or urine samples. Methylmalonic aciduria confirmed with high level of urine methlmalonic acid and Methylmalonic aciduria confirmed by increased of urine methylmalonic acid Other examination such as elevated homocysteine??, methylmalonic acid, or formioglutamic acid (FIGLU in the urine can confirm the diagnosis of cobalamin Methylmalonate requires vitamin B12 for its metabolism. High elevated urinary picolinate, supplemental mineral-picolinate salts may be contributing sources.
