Albumin, IgG, Retinol-Binding Protein, and alpha1-microglobulin Excretion in Childhood

Pediatr Nephrol. 1998 May;12(4):290-2. doi: 10.1007/s004670050455.

Abstract

Urine concentrations of two high molecular weight proteins, albumin and IgG, and two low molecular weight proteins, alpha1-microglobulin (A1M) and retinol-binding protein (RBP), were measured in 657 healthy children from birth to 18 years of age. The urinary levels of RBP and A1M suggest an age-dependent decline, whereas the levels of albumin and IgG show an uneven distribution. Reference values for albumin, IgG, A1M, and RBP for each group are reported.
