title: The excretion of insulin in urine.
abstract: The concentration of biologically active insulin was measured by the isolated fat cell method in serum and urine from healthy subjects and compared with the concentration of immunoreactive insulin. In both urine and serum the values obtained by the two methods correlated closely; In addition, there was a close correlation between the concentration of biologically active and immunoreactive insulin in urine from maturity onset diabetics. Therefore, conclusions on the excretion in the urine and the urinary clearance of insulin, which are based on measurements of immunoreactive insulin, are also valid for biologically active insulin.
