Formiminoglutamate (FIGLU) is a functional marker of insufficiency of folic acid, another B-vitamin, and is a compound made from the amino acid histidine.

Pregnant women especially need to have adequate folic acid to prevent birth defects. Folic acid insufficiency can play a role in childhood development problems, depression, immune function, and is a risk factor for cardiovascular disease.

Insufficiency of folic acid leads to high urinary Formiminoglutamate.
