Background and clinical significance

This test is useful for the identification of hyperoxaluria, a condition that may result in kidney stone formation, nephrocalcinosis, progressive kidney damage and systemic calcium oxalate deposition. Primary hyperoxaluria is a group of inherited metabolic disorders affecting glyoxylate metabolishm (types I, II, and III) that may be differentiated by respective elevations in glycolic acid, glyceric acid and glyoxylic acid.

Disease condition

Primary hyperoxaluria type I (PH I), primary hyperoxaluria type II (PH II), and primary hyperoxaluria type III (PH III)
