The Amazing COVID-19 Ab(IgG/IgM) Sealing Tube Test Strip is a machine-free, diagnostic lateral flow test. With a painless prick to the finger, a drop of blood is released onto a cartridge to evaluate for the presence of COVID-19 specific IgG and IgM. The test targets the nucleocapside protein as well as the spike protein. A patient’s immune system produced these protein antibodies to fight and clear out the SARS-CoV-2 virus.
Besides rapid antigen tests, the antibody test can help determine if individuals can return to the workforce without risk of being infected and infecting others. Analyzing these tests can assist epidemiologists and public health personnel to better understand disease spread.
They provide a clearer look at disease exposure and risk of future outbreaks in the community. Most importantly, people who have recovered may be able to donate a part of their blood, called convalescent plasma, which can boost the ability for others to fight the virus.
