Two types of COVID-19 tests are available to conduct at home. Antigen products detect proteins on the coronavirus surface, while molecular PCR tests identify viral RNA. The antigen versions can be processed at home with results available quickly. A home PCR test swab must be sent to a lab for processing.
The main issue with the antigen test is its lower accuracy rate. However, many people prefer the convenience and fast results. A second antigen test after 24 hours is recommended.
How It Works
A home PCR test for COVID-19 works in a complex series of steps. It searches the fluid on the swab for a specific genetic sequence. If this is found, further steps amplify it to more detectable levels. Even the tiniest quantities, such as one RNA molecule per microliter, can be detected this way.
A Brief History
Although the COVID-19 test is new, the PCR model was invented in 1983. The scientist, Kary Mulls, was awarded the Nobel Prize for this invention in 1993.
Advantages
Home testing has several advantages, even when swabs must be shipped to a lab.
For instance, a person who is not feeling well doesn’t have to go somewhere for testing. Even when the procedure is performed outside by a technician, this can be unpleasant for someone experiencing fatigue, fever, or chills.
In addition, home testing requires no money spent on gas and no time traveling to a healthcare facility or pharmacy. Sometimes, even with an appointment, people must wait in line.
