Function and principle of quantitative detection kit

Quantitative test kits are mainly used to detect the presence of specific substances (such as viruses, bacteria, cancer cells, etc.) and can give specific values to provide quantitative results. These kits are widely used in medical testing, food testing, environmental testing, industrial testing and other fields.

For example, in the medical field, quantitative test kits can be used to detect specific substances in blood, urine, cell samples, etc., such as tumor markers, blood sugar, antigens, antibodies, etc. By using these kits, doctors can understand the patient's condition more accurately and develop more effective treatment plans.

In addition, quantitative test kits are also helpful in judging the safety of food in the field of food testing. They are also widely used in the industrial field, such as the detection of residual chemicals in oil products and the detection of volatile organic compounds in rubber. Therefore, quantitative test kits play a vital role in quality control, regulatory compliance, and preventing false positives or false negatives.

The principle of quantitative detection kits is mainly based on the specificity of antigen-antibody reaction. When the indicator substance in the quality detection kit binds to the target antigen or antibody, a complex will be formed. The remaining target antigen or antibody still maintains the original antigen-antibody complex ratio. At this time, the enzyme-labeled antibody or antigen is added to form an enzyme-antigen-antibody complex. Under the measurement conditions, if the concentration of the indicator substance can be completely reacted by the enzyme marker, the color reaction will be inhibited, and the depth of the color reaction can reflect the amount of the substance to be measured. Therefore, the quantitative detection kit can quantitatively detect the content of a specific substance in the body.
