The Covid-19 IgG/IgM Antibody Rapid Tests by Healgen Labs and Assure Technologies are two of the most accurate tests on the market. These tests identify qualitative and differential detection of SARS CoV-2 antibodies to determine whether you’ve had exposure to COVID-19 and have developed antibodies that potentially protect against the virus or if you have early antibodies indicating ongoing infection. This test is not used to diagnose active or acute SARS-COV-2 infection. If acute infection is suspected, direct testing by molecular methods for SARS-COV-2 is necessary.
Attached is some CDC information regarding Antibody Testing.
Antibody testing is a simple blood test that reveals IgM’s that may be present in early infection or pre-symptomatic individuals, and IgG’s that are produced in response to infection. Though not a magic bullet, a past infection does offer some degree of immunity for some period of time. Bonus if you get an IgG, Plasma donations from recovered candidates are in great demand! We test employees with both solutions which provide a clearer picture of incidence and prevalence in the community and in your workplace.
Igm and IgG
IgM antibodies to SARS-COV-2 are generally detectable in the blood several days after initial exposure, although the duration of time these antibodies are present post-infection is not well characterized. A positive IgM indicates the need for diagnostic testing to determine the presence of COVID-19.
IgG antibodies to SARS-COV-2 are generally detectable in the blood several days after initial infection, although the duration of time antibodies are present post-infection is not well characterized. At this time it is unknown for how long antibodies persist following infection and if the presence of antibodies confers protective immunity.
This test is intended for the use as an aid in identifying individuals with an adaptive immune response to SARS-COV-2, indicating recent or prior infection. Results are for the detection of SAR-COV-2 antibodies.
Individuals may have a detectable virus by molecular testing present for several weeks following seroconversion. Negative results do not preclude acute Sars-Covid-2 infection. This test should not be used to diagnose acute SARS-COV-2 infection. If an acute infection is suspected, direct testing by molecular methods for SARS-COV-2 is necessary. False-positive results for the test may occur due to cross-reactivity from pre-existing antibodies or other possible causes.
