Plasma clearance of technetium-99m-labeled diethyltriaminepentaacetic acid (DTPA) was used as an indicator of baseline GFR and, after intravenous infusion of 10% mixed amino acids, stimulated GFR.
Because of a reduction in muscle mass in these patients, serum creatinine may be within the normal range, even with a very low GFR. The use of blood urea nitrogen (BUN) concentration as a measure ...
Most of these trials have several confounding variables -- i.e, serum creatinine, renal blood flow, and urine volume -- that limit the applicability of the results. Although low-dose dopamine has ...
