Biochemical detection has a variety of methods, the general usage are the end point method, rate method, two-point method and so on. The delay time refers to from the time when the measured liquid enters the colorimetric cup to the time when the actual test begins.
Therefore, in order to make the specimen to be measured in the colorimetric pool temperature balance and micro bubbles disappear, a certain delay is necessary. In general, most end point methods have a delay of 5 seconds, while the rate method should not be less than 10 seconds below 25 ° C, the delay should not be less than 12 seconds below 30 ° C, and the delay should not be less than 15 seconds below 37 ° C. In addition, the reagent blank is generally selected by the two-point method, while the rate method does not have a blank.
