Safe, Rapid Curbside Testing

Our COVID-19 (SARS-CoV-2) test is performed through a chromatographic immunoassay machine for the rapid detection of COVID -19. This test detects antigen which indicates current active disease and is not a PCR or antibody test. Our test does not require a deep nasopharyngeal swab; it is an anterior nasal swab with 99.5% accuracy. Please refer to the Q&A section for more details.

The evaluations and tests are done from the comfort of your vehicle. We ask that all patients wear a mask and practice social distancing while waiting for their appointment.

When to Seek Testing

For best results, antigen testing should be performed within the first 5 days of the onset of symptoms.  We can also provide testing if you are asymptomatic but have been exposed to a person who has tested positive for COVID-19.  Lastly, we can provide testing if you would like to be screened for COVID-19 even though you have no symptoms and no known exposures.

How it Works

Register online by clicking on a “schedule a test” button – you will need to complete your registration, choose an available time slot, and pay online.

  • Arrive at scheduled time to the East side of the building and park in one of the designated spots. Please wait for a staff member to come to your window to collect a sample.
  • Please keep your mask on until told to remove. After verifying your name, staff member will insert the collection swab about 1 inch into each nostril and roll the swab 5 times along the mucosa to ensure both cells and mucus are collected.
  • Once sample is taken, our staff will begin the testing process.
  • After results are in, Gretna Health will notify you via email in about 30 minutes.

Interpreting Your Test Results

Positive Test Result

The probability that the positive result is incorrect is less than 1%.

Your sample contained antigens from the virus that causes COVID- 19 (SARS-CoV-2). We advise you to contact your primary care physician and self-quarantine immediately to avoid any spread of the virus throughout the community. Self -quarantining involves staying home and distancing yourself from others as much as possible.  Continue to self-monitor by taking your temperature regularly, watching for signs of symptoms such as shortness of breath, fever, cough, diarrhea, headache, congestion and body aches.

If you have any underlying health conditions, such as, cancer, COPD, pregnancy, heart conditions, sickle cell disease, type 2 diabetes, chronic kidney disease, or are in an immunocompromised state (weakened immune system) – please make sure to contact your primary care provider.  If you have an emergency warning sign, seek emergency medical care immediately.

Negative Test Result

The probability that the negative result is incorrect is 1.8%.

Your sample did not contain any antigens from the virus that would cause COVID- 19. If you are not experiencing symptoms, you can return to your normal routine. If you ARE experiencing symptoms and are concerned that you may have COVID-19 because you may have been exposed, please reach out to your primary care physician to discuss further options. It is recommended to continue to self-monitor and if you show symptoms, remember to self-quarantine immediately to prevent the spread and contact your physician.

Frequently Asked Questions

Does Gretna Health perform antibody testing?

No, Gretna Health only has the ability to do rapid antigen testing for COVID–19 at this time. Check back for updates.

What is an antigen test versus an antibody test?
  • Antigens are molecules or toxins that stimulate an immune response. When infected with COVID-19, the body produces antibodies that bind to antigens to help eliminate the virus.  These antigens can be detected through an antigen test offered at Gretna Health.
  • Antibodies are proteins produced by the immune system in response to the exposure to specific antigens. Antibody tests are not typically used to diagnose current infection, as it takes the body some time to produce antibodies. An antibody test can reveal if a person has already been infected by COVID-19.
Can you get the COVID-19 vaccine at Gretna Health?

No, we do not yet have access to the vaccine for COVID-19. Check back for updates.

Can you get reinfected if you have already had COVID- 19?

It is not yet known if a person’s own antibodies to COVID-19 will protect them against reinfection. We recommend you continue to take steps to avoid contracting the virus even if you have been diagnosed positive in the recent past.

How does the COVID-19 virus spread?

Respiratory droplets or small particles are transmitted when an infected person coughs, sneezes, sings, talks or breathes.

What if my spouse or someone who lives with me tests positive, but I have no symptoms?

Keep a safe distance from the infected individual if possible. Takes steps such as using separate bathrooms and bedrooms if possible. Wash your hands and wear a face mask to help reduce your chances of infection and monitor your symptoms daily. If you show any signs or symptoms – self-quarantine immediately and schedule testing.

How do I tell the difference between seasonal allergies and COVID- 19?

Unfortunately, some of the symptoms are very similar and it may be difficult to distinguish the difference between the two. To confirm your diagnosis, it is recommended to get tested.

How old do you have to be to test?

Gretna Health is testing ages 6 and older at this time.

What kind of machine is being used and is it FDA approved?

Our machine, the Veritor Analyzer Plus, version 5.4, is manufactured by Becton-Dickinson (B-D). This machine has an EUA (Emergency Use Authorization) for COVID-19 testing. This means that the FDA has authorized its use for COVID-19 testing during the current pandemic state of emergency.
