New strains of the virus that causes COVID-19 are emerging every few months. These new strains are very contagious and are spreading quickly worldwide. It is a good idea for people with respiratory or other cold or flu-like symptoms to find out whether they have COVID-19.

Symptoms that look like a common cold can actually be milder symptoms of COVID-19. If you have COVID-19, you can become a source of infection for the people you come in contact with.

If you want to know your COVID-19 status, you can opt for in-house rapid molecular COVID testing.

What is in-house antigen COVID testing?

In-house antigen COVID testing is a diagnostic test that is used to detect specific proteins (antigens) of the coronavirus in a specific concentration to identify individuals suffering from COVID-19.

When a specific antigen is present in a sample, it will bind to specific antibodies on a paper strip. A positive signal will be generated within 10 minutes if a specific antigen concentration is present in the sample.

The in-house antigen COVID test is available at AfterOurs Urgent Care.

Test purpose

The purpose of in-house antigen COVID testing is to rapidly detect COVID-19 illness. This information will help guide treatment as well as self-isolation or quarantine decisions.

Significance of in-house antigen COVID test

The benefits of this test are:

  • Convenience of use
  • Easy to perform
  • Results within 10 minutes

Procedure

In house antigen testing consists of the following steps:

  • During the first step, a sample is taken from the nose with a cotton swab
  • This sample is mixed with a liquid called a reagent and placed in a tube with a test strip
  • After 10 minutes the test strip will show a positive or negative result.

Test results

The in-house antigen COVID test results can be positive, negative, false positive, or false negative.

Positive result:

If a positive line appears on the test strip, it is likely you have COVID-19. A medical provider can help determine whether further confirmation is needed based on your history and symptoms.

Negative result:

If no positive line appears on the test strip, it is unlikely that you have COVID-19. Again, a medical provider will work with you to see whether further confirmation is needed.

False-positive and false-negative results:

A false-positive is when diagnostic tests show positive results but, in reality, a person is not suffering from disease. Similarly, a false-negative is when a person does suffer from active disease, but the diagnostic test shows negative results. False-positives and false-negatives are rare. A qualified medical practitioner can help determine whether a false positive or negative has occurred.
