A study into the measurement of α‐amylase activity using phadebas, iodine and gel‐diffusion procedures Available to Purchase

The α‐amylase activity of ten human saliva samples was measured using phadebas, iodine and gel‐diffusion procedures. Highly significant correlations (p = 0.001) were found between the results of the three methods, namely phadebas and iodine r = –0.907, phadebas and gel diffusion r = +0.928, and iodine and gel diffusion r = –0.948. The suitability of the three methods for use in an educational context is discussed.
