Comparison of dry chemistry and wet chemistry testing principles

release time:2021-09-09 10:41:04

Biochemical analysis is one of the most important tools commonly used for clinical diagnosis. Biochemical analysis can be divided into wet chemistry and dry chemistry according to whether the chemical reaction between the sample and the reagents is in solid phase or not.

With the increasing clinical demand for emergency biochemical test results in terms of reporting time. As well as the rapid development of clinical biochemical testing technology. Emergency biochemical testing techniques are gradually developing from traditional wet chemistry to dry biochemistry.

Principle of dry chemistry and wet chemistry testing

A. Dry chemistry

Dry chemistry uses a solid phase reagent technique with a multilayer film. Simply add the liquid sample directly to a reagent carrier that has been solidified in a special structure, i.e. dry chemistry.

The water in the sample is used as a solvent to dissolve the reagents cured in the carrier and then chemically react with the components to be measured in the sample for analytical determination.

B. Wet chemistry

Wet chemistry is the ordinary chemical reaction. It is a chemical reaction that occurs when a liquid reagent and a sample are added to a reaction vessel and mixed. Dry chemistry is only relative to wet chemistry. It is actually a chemical reaction that also takes place under humid conditions.

Comparison of test results between dry and wet biochemical analyzers

According to the existing research, the R (correlation coefficient) of all analytical items of the two methods is greater than 0.93, and the correlation test P<0.05. The statistical results show that the analytical results of the two instruments are well correlated. Both methods can meet the needs of clinical testing.
