摘要： When assessing the start time of the limulus reaction between biogenous biologically active substances and LAL and using the reaction start time to determine the concentration of the biogenous biologically active substances, in order to exclude the influence of progressive changes which occur regardless of the conditions of the limulus reaction, the strength of transmitted light or scattered light in the liquid mixture of the measurement sample and LAL is detected, the variation (delta) in the transmittance or number of gel particles is acquired at set intervals, and the time when the variation (delta) crosses a threshold value is taken as the reaction start time. Furthermore, the time intervals when acquiring the abovementioned delta are not uniform, and either change over time from the start of measurement as defined by a time function, or multiple sequences with differing time intervals are prepared in advance.
