Propionylglycine

Propionylglycine is an organic acid found in urine that indicates how your body metabolizes certain amino acids and fatty acids. Elevated levels can suggest propionic acidemia or methylmalonic acidemia, rare inherited disorders that disrupt metabolism and can cause seizures, developmental delays, and organ damage. This test is particularly important in newborn screening programs and for investigating unexplained symptoms in infants and children. Early detection enables specialized dietary management and medical treatment to prevent serious complications.
