Did you ever wonder how antigen tests work, but didn’t know who to ask. We decided to explain it right here to clear our own minds. Governments use rapid antigen tests to probe for the presence of an antigen suggesting an infection. This contrasts them from antibody and nucleic acid sampling that probe for other information.
Why Antigen Tests Are Preferred for Quick Sampling
Well firstly, antigen tests are quick and simple. A health worker inserts a sterile swab up a patient’s nostril, and rotates it four times. They then place the swab in a device that extracts the liquid and analyzes the results within 15 minutes. However, these results must rest for further 15 minutes to ensure an accurate, settled result.
If you wondered how antigen tests work technically-speaking, it’s pretty straightforward too. They separate a bio molecule from the sample mixture and produce user-friendly results we can see with our own eyes. Health care workers use them because antibody-detecting rapid tests can’t work right away. Whereas foreign antigens that trigger immune responses manifest far sooner.
Now You No Longer Wonder How Antigen Tests Work
Now you know how quick and easy, and safe these tests are, we’d like to encourage you to take the test whenever asked. Rapid antigen testing is not just for COVID. The technology predates HIV and we have not heard of side effects except for occasional pre-test anxiety.
The only way to stop COVID, and return to normality is for us to break the infection chain. A person with the virus can innocently affect others before their symptoms show. These could be vulnerable people with ‘comorbidity’ diseases that could to make them really ill. It makes sense to fight the pandemic together. Because together we can send it packing!
