Method for quantitatively determining glucoamylase in human urine and body fluids

摘要

A method for quantitatively determining glucoamylase in human urine and body fluids which comprises removing low molecular weight substances from a human urine or body fluid sample, adding to the resulting sample which is free of low molecular weight (from about 500 to about 20,000) substances maltotriitol, phenyl- alpha -glucoside or 2,4-dinitrophenyl- alpha -glucoside, which are specific substrates for glucoamylase, and quantitatively determining the glucose, phenol or 2,4-dinitrophenol which is a degradation product of the above substrates, respectively.
