MEASUREMENT OF GLOMERULAR FILTRATION RATE BY INULIN CLEARANCE WITHOUT URINE COLLECTION

A continuous infusion method for measuring • inulin clearance (and hence glomerular filtration rate) which does not require urine collection has been re-evaluated and found to give satisfactory results. In two non-oedematous and anephric patients the plasma level of inulin became virtually constant four hours after a single intravenous dose, and hence this is the minimum time required for the infusion with this method. © 1969, British Medical Journal Publishing Group.
