DOI: 10.1080/00365513.2025.2585469
Abstract: Abstract The concentration of methylmalonic acid (MMA) in plasma increases in patients with cobalamin deficiency (CD). Independent of the cobalamin status, MMA also increases with decreasing glomerular filtration rate (GFR). Therefore, the physician who assesses… read more here.
