Why can antibody tests be used to diagnose SARS-CoV-2?
In the "Diagnosis and Treatment of SARS-CoV-2(Trial Version 7)" released by the National Health and Medical Commission on March 3, 2020, suspected cases with positive detection of SARS-CoV-2-specific IgM and IgG antibodies as one of the clinical diagnosis criteria .
IgM is the earliest antibody to appear in the primary humoral immune response.The increase in IgM in the serum indicates that a recent infection has occurred and can be used for early diagnosis of infection.
IgG is the antibody with the highest content in serum and body fluids.It is the main antibody produced by the re-immune response.It has high affinity, is widely distributed in the body, and has important immune effects.
After the new crown virus infects the human body, the body will generate corresponding specific antibodies to resist the virus.We can use colloidal gold immunochromatography to find the specific antibodies in the serum samples of patients with suspected new crown pneumonia to help determine the patient's infection status. Principles of the SARS-CoV-2 Antibody Detection Kit.
Advantages of the SARS-CoV-2 lgM / lgG detection kit
Simple and safe operation
Add the sample to the test card first, and then add the sample dilution solution to complete the operation. The whole blood / serum / plasma sample type can be used to reduce the exposure risk of respiratory sample collection to medical staff.
High sensitivity
lgM / lgG antibody test can distinguish recent acute infection and long-term infection. It can complement the combined detection of nucleic acid and can effectively compensate for the risk of missed detection of nucleic acid detection. The role of timely diagnosis and control.
Fast detection speed
The result is obtained in 15min, the detection result is directly interpreted, no equipment is required.
Rapid shunting
Rapid shunting of suspected cases, especially those with hidden infections, effectively preventing the spread of the epidemic and alleviating the current huge clinical diagnosis and treatment pressure.
Widely applicable
It is suitable for early screening and early diagnosis of outpatient and outpatient clinics and hot clinics in community health service centers, primary hospitals, and tertiary hospitals.
