How is a Covid-19 Antigen Rapid Test performed?

Oris uses the nasopharyngeal (nasal swab) method of specimen collection.

1. You will be asked to tip your head back 70%.
2. A mini-tip swab with a flexible shaft will be placed through the nostril parallel to the palate until resistance is encountered or the distance is equivalent to that from the ear to the nostril of the patient, indicating contact with the nasopharynx.
3. The swab will be rolled and gently rubbed.
4. The swab sample will then be placed in a tube containing liquid.
5. Three drops of the sample will be placed on the strip.

What do I need to bring with me?

Please bring a goverment-issued photo ID, such as a Driver's License, Passport, or State ID card.

How long does the test take?

The Covid-19 Rapid Test usually takes about 30 minutes, including the 15-minute required wait time after the specimen is placed on the test strip. Please note that time can vary!

What does a positive test mean?

The “gold standard” for clinical diagnostic detection of SARS-CoV-2 remains RT-PCR. Thus, it may be necessary to confirm the results of a rapid antigen test result with a nucleic acid test. When confirming an antigen test result with a RT-PCR test, it is important that the time interval between collection of samples for the two tests is less than two days, and there have not been any opportunities for new exposures between them. If you test positive, you do not need to repeat a test for at least 3 months. In most cases, negative antigen diagnostic test results are considered presumptive. CDC recommends confirming negative antigen test results with an RT-PCR test when the probability is relatively high, especially if the patient is symptomatic or has a known exposure to a person confirmed to have COVID-19.

How do you read the strip?

The strip is read based on the absence or prescence of a colored line in certain control areas, and a change in color in other control areas. Rapid antigen tests perform best when the person is tested in the early stages of infection with SARS-CoV-2 when viral load is generally highest.

Who should get a Covid-19 test?

Diagnostic testing for SARS-CoV-2 is intended to identify a current infection when a person has symptoms consistent with COVID-19, or when a person is asymptomatic but has recent exposure to SARS-CoV-2.

How is a Covid-19 Rapid Test performed?

Oris uses the fingerstick method of obtaining whole blood. The blood drop is then collected using a disposable pipette, after which a drop is placed on the test strip. Two drops of buffer is then added. After a 15-min wait period, the strip is read by a technician.

What does a positive test mean?

Antibodies start developing within 1 to 3 weeks after infection, so, in general, a positive antibody test is presumed to mean a person has been infected with SARS-CoV-2, the virus that causes COVID-19, at some point in the past. Antibodies to SARS-CoV-2 are generally detectable in blood following an initial infection, and individuals may have a detectable virus present for several weeks following seroconversion. If IgG antibodies are present, it often indicates a past infection but does not exclude recently infected patients who are still contagious.
