The COVID-19 Test is a rapid cassette test that will deliver results in minutes with 98.2% accuracy.
The test detects antibodies specific to SARS-CoV-2 (COVID-19). Using a blood sample from a lancet device finger poke, it can determine exposure to SARS-CoV-2 quickly and effectively.
IgM antibodies are the largest antibodies in the body and are typically produced first when an individual gets infected by a virus. IgM antibodies make up about 5% to 10% of all the antibodies in the body. They are found in the blood and lymph fluid.
Because the body typically produces IgM antibodies first, the IgM panel can detect the SARS-CoV-2 virus early. Therefore, IgM panels can accurately detect “acute infection.”
IgG antibodies are the smallest and most common antibodies. They make up about 75% to 80% of all the antibodies in the body. They are also the only type of antibody that can travel across the placenta from a pregnant woman to her unborn child. IgG antibodies can be found in all body fluids.
Unlike IgM antibodies, the body produces IgG antibodies much later. As a result, IgG antibodies can only be detected in the later course of the illness. Scientists use the IgG panels to detect “recent infection” or “in-recovery” states. An antibody testing with positive IgG with negative IgM results indicates that a person who has been exposed to or infected with COVID-19 and now has protection against COVID-19.
The Importance of Serological Testing
Patients who test positive after serological (antibody) testing [Positive IgG but negative IgM,] have built up protection against COVID-19. Antibody tests are useful for determining which individuals can resume their normal activities due to their body’s new resistance to SARS-CoV-2.
Take healthcare workers for instance. These heroes are needed on the front lines to care for patients who are infected by COVID-19. For them to be successful at their job, they need to be healthy. Serological testing is important for this category of workers to ensure that they are protected against the virus.
The value of serological testing goes beyond just healthcare workers. It will prove beneficial for all essential workers, including film productions, law enforcement officials, grocery store cashiers, bus drivers, firefighters, delivery workers, people in the food business, security guards, and maintenance workers.
