Why We Need Antigen Swab Tests for COVID-19

Why We Need Antigen Swab Tests for COVID-19

When you need to know right away whether someone is actively infected with the COVID-19 virus, the Antigen Swab Test can provide quick results. They are accurate, cost-effective, and simple to self-use and interpret.

The Antigen Swab COVID-19 test detects whether the patient has antigens that are present during infection of the virus. A swab is used to take a sample from the back of the nose or throat and the sample is mixed with a solution. Similar to a pregnancy test, the solution is then applied to a paper strip that will reveal whether a person is currently infected.

Results can appear in as little as 15 minutes so you can get your result right away. Another benefit is that very little equipment and personnel are required to administer Antigen Swab Tests. Because of how easy they are to use and how quickly results become available, these tests are also ideal if large groups of people need to be tested at the same time. The downside is that the tests can only detect current, high viral loads. This means that people who have lower viral loads may get a false negative. This is one reason why frequent testing is recommended if you are using Antigen Swab COVID-19 tests.

Laboratory PCR Tests

Polymerase chain reaction (PCR) tests are one of the most widely used COVID-19 diagnostic tests. Like Antigen Swab Tests, PCR tests use a nasal and throat swab. Where it differs is that the sample is then sent off to a laboratory to be tested for COVID-19. The PCR test is more accurate and is able to detect active coronavirus as well as tell if the patient previously had it, but this accuracy is more expensive and time-consuming.

Depending on how busy the laboratory is, it can take anywhere from 24 hours to several weeks to find out the test results. These tests are best suited for those who want high accuracy but do not need results immediately. They are also not as efficient for testing multiple people at once.
