COVID-19 Rapid Antibody Test
COVID-19 IgG/IgM Rapid Test Cassette is a solid phase immunochromatographic assay for the rapid, qualitative and differential detection of IgG and IgM antibodies to 2019 Novel Coronavirusi in human whole blood, serum or plasma.
This test provides only a preliminary test result. Therefore, any reactive specimen with the COVID-19 IgG/IgM Rapid Test Cassette (Whole Blood/Serum/Plasma) must be confirmed with alternative testing method(s) and clinical findings.
The test is conducted by taking a small finger-prick blood sample, placing droplets of blood in the center of the cassette. Then add two drops of the buffer solution. Read test results in 10-15 minutes. This test should be conducted only by a licensed medical professional or licensed phlebotomist.
- Read screening test results in 10-15 minutes
- For medical professional use only
- Detection Window IgM: Symptomatic 3-5 days, Asymptomatic 7 days
- Test Medium: Whole blood, plasma and serum samples
- Test kits can be stored at room temperature or refrigerated
- Test kits have a 18 month shelf life from manufacture date
What is the difference between IgM and IgG antibodies?
IgM is the first antibody to be produced in response to any antigen (foreign particle) invasion, while IgG is most abundantly found antibody in the human body. IgM is the largest immunoglobulin among all, with pentamer units and ten antigens binding site. IgG are responsible for humoral immunity and is a monomer unit which is lighter and smaller, with two antigen binding site. Due to the smaller size of this antibody, it is able to travel through the bloodstream.
Simply put, IgM will be the first antibody produced by the body if a virus is present in the body. While IgG is the second antibody produced by the body in response to a virus, it will remain longer and is an indicator that the body has produced some level of immunity. There is no final data that suggests the presence of IgG antibodies will protect against future COVID-19 exposure.
