Maternal plasma and urine concentrations of beta2- microglobulin and gamma-glutamyl transpeptidase (EC:2.3.2.2) were measured serially in normal pregnancy. These parameters remained constant throughout and can therefore be used to evaluate tubular function in pregnancies complicated by renal disorders.
