Why Serology Testing / Rapid Test For COVID-19?

Covid-19 serology testing will allow us to develop a better understanding of how the virus spreads and the true denominator to determine statistics like fatality rates. Serology tests use a patient’s blood, serum, or plasma to identify the presence of IgM and IgG antibodies. Serology testing allows the determination of active infection and whether someone has built up an immunity to the virus based on past exposure. Unlike PCR (SWAB)based testing, Serology testing provides rapid results in 10-15 minutes.

  • Typically, IgM peaks at day 5
  • IgG peaks at 14-21 days
  • IgM appears first and then slowly drops off. As IgM disappears and IgG picks up, this indicates the patient is likely entering recovery and at some point no longer contagious.
  • IgM and IgG are helpful bio-markers to make determinations of patients’ immune status, whether or not they are contagious, recovering, etc.

So What Method of Testing is Better? Swab or Rapid Test?

Rapid COVID tests are a great option to inexpensively and quickly have insight into what is going on. This is a solution that will allow hundreds of thousands of more patients to be tested while allowing for a better understanding of how the virus spreads and fatality ratios.

Additionally, there is an application for IgG testing. The presence of IgG means that the patient has mounted an immune response following exposure to the virus. These individuals may have been asymptomatic and never tested or may have had mild symptoms that passed. This could be useful in making determinations for staffing surgical floors or for responders on the front-line dealing with the next wave of the virus

Reliable Test

The COVID-19 IgG and IgM Rapid Test are used for the qualitative detection of SARS-CoV-2 antibodies in whole blood, serum, or plasma. The procedure is easy to administer and offers reliable results at 10 minutes that remain valid for 20 minutes.

  • (SWAB) PCR tests are able to identify the virus before the antibody test. Serology tests are not as effective at identifying infection in the pre-symptomatic or early symptomatic stages. PCR may decline rapidly in 3-6 days. (1)
  • PCR begins to lose sensitivity by 3-6 days. IgM serology (Rapid Test) starts becoming very sensitive and showing positives at 5 days. There are situations in which a patient comes in for testing around this time and a PCR based test could be negative, but IgM could be positive. There is a period of time where IgM becomes more sensitive than PCR.
