There are 3 main categories of coronavirus in the United States: two diagnose if you have an active infection and a third indicates whether you have ever had the virus.
Here’s how they work:
Most tests look for fragments of the virus’s genetic clothing and require a nasal pattern that is taken through a fitness professional and sent to a lab. It is considered to be the most accurate way to diagnose an infection, but it is not perfect: The pattern should be smart enough for any virus to be detected.
These tests take hours to treat in the lab, so you probably won’t be able to get effects for at least a day, even if a few quick tests take about 15 minutes on site. Other genetic tests use saliva instead of a torunda.

A new type of check is looking for proteins discovered on the surface of the coronavirus, in addition to the virus itself. These antigen checks are just coming to market, and experts hope they will help expand checks and accelerate results.
Antigenic testing is not as accurate as genetic testing, but they are cheaper, faster, and require less specialized laboratory equipment. They require a nasal pattern through a fitness professional.
A recent approval through Abbott Laboratories takes 15 minutes and can be done in schools, offices and other places.
Antiframe tests look for proteins that the framework produces to fight infections in a patient’s blood sample. Antibodies are a sign that a user in the past had COVID-19.
Scientists still don’t know if antibodies protect others from another infection, or how long this shield can last. Antibody testing is especially useful for researchers who measure which component of the population has been infected.
