[Adaptation to Gemsaec centrigugal analyser of a method of turbidimetric estimation of amylase (author's transl)]

Hydrolysis of a solution of amylopectin by serum or urinary amylase leads to a reduction of the turbidity of this solution, observed at 340 nm. Adapted to centrifugal analysis, this method permits 15 estimations in 3 minutes with a serial reproducibility of 2.7 per cent, and a daily reproducibility of 6 per cent. The correlation with a nephelemetric method of estimation gives r = 0,969, with an enzyme method r = 0,957 and with an amyloclastic method, r = 0,919.
