What Are The New Methods of SARS-CoV-2/COVID-19 Detection?

The SARS-CoV-2/COVID-19 detection reagents currently approved for marketing mainly include two types, one is nucleic acid detection reagents and the other is antibody detection reagents.

With the progress of disease recognition and research and development, more testing reagents and methods will be put into used in the future.

The first type of nucleic acid detection process includes specimen processing, nucleic acid extraction and PCR detection.

The average detection time takes 2-3 hours. Because it directly detects the viral nucleic acid in our collected samples, it has strong specificity and relatively high sensitivity and is currently the main detection method.

The second antibody detection includes colloidal gold method and magnetic particle chemiluminescence method, in which the average detection time of colloidal gold method is about 15 minutes.

The magnetic particle chemiluminescence method generally takes 30-60 minutes. Antibody detection is to detect the antibody level in the human blood. In the early stage of infection, the human body may not have produced antibodies, so it has a window period for detection.

Therefore, antibody detection can be used to assist in the diagnosis of cases with negative nucleic acid tests and can also be used for screening and screening of cases, but it cannot replace nucleic acid detection methods.

Benefits of COVID-19 IgM IgG Rapid Test Kit

After being infected with the new coronavirus, the patient starts the immune defense reaction of the immune system, and the IgM antibody is first produced in about 3 to 7 days, and the IgG antibody is also raised immediately.   

Therefore, if the serological test can be carried out simultaneously with the nucleic acid test, it can effectively verify the infection of the new coronavirus and increase the diagnostic methods.

Serological early diagnosis of IgG / IgM is an important indicator to help the management of patients with clinical needs.Provides important technical support for large-scale employee medical screening
