How COVID Rapid Antigen Tests Work

COVID rapid antigen tests use a unique biochemical reaction to detect the presence of the virus in a sample. The test involves using salt, gold particles, and paper with antibodies to provide quick and relatively accurate results.

Once a sample is collected, it is mixed with a buffer solution that locks the pH at 7.4, similar to the human body’s pH. The gold nanoparticles and antibodies in the solution react to detect the presence of the COVID virus, resulting in a color change for a positive test. A negative test is essentially a lack of a positive test.

Detecting the Omicron Variant

For the Omicron variant, it is suggested to swab the back of the throat and nose to detect the highest viral load. This method can increase the accuracy of the test results.

Ensuring Accurate Test Results

The accuracy of the test results depends on how well the test is performed and the viral load in the body. The goal of at-home COVID-19 tests is to ensure that the T level never changes color within the allotted time.

However, it is important to note that using substances like soda or juice can alter the pH of the sample and lead to inaccurate results. To avoid this, it is recommended to use the original buffer solution to check for any tampering.

The Future of Antigen Tests

The speaker hopes that this technology can be used in the future for flu testing. They encourage people to continue wearing masks and prioritizing public health.

Conclusion

In conclusion, COVID rapid antigen tests use a unique biochemical reaction to detect the presence of the virus in a sample. To ensure accurate test results, it is important to follow the suggested procedure and use the correct buffer solution. The future of antigen tests looks promising, and we should continue to prioritize public health by wearing masks and following recommended guidelines.
