Micromodification of the Phadebas amylase test

A micromodification of the original Phadebas Amylase Test has been adapted for the LKB Calculating Absorptiometer. This test requires only 15 mul of serum and reduces the amount of reagent used by a factor of ten. The results of this semiautomatic micromethod have a coefficient of variation of about 4% and correlate well (r = 0.996) with the method as originally described.
