label_lc: impaired renal tubular reabsorption of low molecular weight protein
description: "Increased loss of low-molecular weight proteins by the kidneys, measured in terms of the fractional excretion (FE). The FE of low-molecular-weight proteins such as beta2-microglobulin can be measured in terms of plasma and urine concentrations, since urinary low-molecular-weight protein concentrations can vary with water reabsorption."
