Abstract
For optical determination of the catalytic enzyme activity of a sample by means of enzyme reactants which are split under the influence of the enzyme to be measured, the enzyme reactant is placed at the end of an optical fiber and brought into contact with the sample to be determined. The measurements are carried out by observing the rate of change in spectral characteristics of the enzyme reactant, or its reaction products, resulting from the enzyme reaction. The method permits measurements of undiluted blood and in-vivo determinations of enzyme activities.
