Anatomy of the COVID-19 Virus
Types of Tests to Detect COVID-19 virus (SARS-Cov2)
This test looks for virus genetic material (DNA) from a nasal pharyngeal or throat swab or by saliva of a SAR-CoV2 virus infected person. Using PCR (polymerase chain reaction) technology will amplify the detection of viral load, if present.
RAPID Antigen Test
Using a nasal or throat swab or by saliva, this test detects the proteins of the virus -antigens – rather than viral DNA. This test is useful to detect if a person is currently infected especially when they have a high SARS-Cov2 virus load.
Post Natural Infection Antibodies Test
As a SARS-CoV2 virus invades the body, our immune system detects viral proteins (antigens) and mounts an immune response by producing antibodies to block antigen effects quickly creating IgM and soon after, longer lasting, IgG antibodies.
