Assessment of glomerular filtration rate during pregnancy using the MDRD formula.
It is now recommended practice to use estimated glomerular filtration rate (eGFR) values to screen for and monitor chronic renal disease. The most frequently used formula in the general population is that described following the Modification of Diet in Renal Disease (MDRD) study whereby serum creatinine is adjusted for age, gender and race. This study evaluates the performance of the MDRD formula in pregnancy by comparing eGFR with measured values obtained by inulin clearance studies in early and late normal pregnancy and in pregnancies complicated by renal disease or pre-eclampsia. Our results indicate that in all situations, MDRD substantially underestimates glomerular filtration rate during pregnancy and cannot be recommended for use in clinical practice.
