What is Infectious Disease?

According to the characteristics and activity characteristics of the immune complex formed by the combination of antigen and antibody.the antigen or antibody in the specimen can be qualitatively, locatively or quantitatively detected.

Qualitative and localized detection is relatively simple, that is, the known antibody is mixed with the sample to be tested.

After a penod of time, if the formation of immune complex occurs, it indicates the existence of the corresponding antigen in the sampleto be tested.

If no expected phenomenon occurs, it means that the corresponding antigen is not present in the sample Similary known antigens can be used to detect the presence of comesponding antibodies in the sample.
