CHAPS Mobile Testing offers two types of COVID-19 tests – the PCR lab test, and the rapid antigen test.


Our team is made up of skilled registered medical professionals who conduct the testing according to guidelines of the NICD and the National Department of Health.


All COVID-19 testing is performed by the GHI Laboratory approved by and in collaboration with the NHLS.

What is the difference between a PCR Test and a Rapid Antigen Test?

The purpose of a PCR test is to detect the presence of genetic material (RNA) from the COVID-19 virus in your nasal or oral cavity. A sample is taken from your nose and throat using a swab. Our laboratory partners will perform this test and make sure that the results are available within 24 -32 hours. You will then receive the result in the form of a certificate in English by e-mail.

A rapid antigen test detects specific proteins — known as antigens — on the surface of the virus and can identify people who are at the peak of infection, when virus levels in the body are likely to be high. Antigen assays are much faster and cheaper than the gold-standard tests that detect viral RNA using a technique called the polymerase chain reaction (PCR). But antigen tests aren’t as sensitive as the PCR versions, which can pick up minuscule amounts of the SARS-CoV-2 virus that causes COVID-19. You will receive the results within 15 minutes.
