COVID-19 Testing

There are 2 types of COVID tests available, the PCR (Nasal Swab) and the Serum Antibody IgG blood test.

A virtual visit with one of our providers is required prior to testing to determine the type of test and the testing location that best fits your medical needs.

Please read below for more information regarding the available tests.

What do the COVID-19 tests detect?

PCR (Nasal Swab): This test will detect if you are actively infected with the COVID-19 virus.

Serum Antibody IgG (Blood Test): This test will detect if you have had prior exposure to COVID-19 and have built an antibody for the virus. For most viral illnesses, a positive antibody means prior exposure to a virus and some degree of immunity to future infection. As COVID-19 is a novel (new) infection, it is unclear if a positive antibody definitively offers immunity. Despite a positive antibody test, the recommendation is to still practice universal precautions.

What testing do I need?

PCR (Nasal Swab):

If you are actively experiencing COVID-19 symptoms such as

  • Fever or chills
  • Cough
  • Shortness of breath or difficulty breathing
  • Fatigue
  • Muscle or body aches
  • Headache
  • New loss of taste or smell
  • Sore throat
  • Congestion or runny nose
  • Nausea or vomiting
  • Diarrhea

If you have a known COVID-19 exposure in the last 14 days

Serum Antibody IgG (Blood Test): 

– If you previously had COVID-19 symptoms (Fever, persistent cough, shortness of breath, body aches) and have recovered after 14 days.

– If you received a positive test result for COVID-19 and have recovered after 14 days.

How are these tests administered?

PCR (Nasal Swab): Administered via a nasal swab. Schedule a virtual visit with one of our providers for testing.

Serum Antibody Blood Test (Total or IgG): Administered via a blood sample.

How long will it take to receive my results and how do I view them?

PCR (Nasal Swab): **At this current time we are experiencing delays with our results, sometimes taking 7+ days due to nationwide demand.** Your results can be viewed via your patient portal account and you will receive an email/text notification once they are available.  

Serum Antibody Blood Test: Generally, it will take about 5 days to receive your antibody results. Your results can be viewed via your patient portal account and you will receive an email/text notification once they are available. 

What platform do you use for testing?

Molecular/PCR tests (active infection only) are sent to our commercial lab partners, LabCorp or Quest Diagnostics.

We are performing the Vitros SARS-CoV-2 Total Antibody test in our lab (tests for IgG, IgM and IgA- both active and past infection). This specific antibody test has approval for FDA Emergency Use and has a 100% specificity. If your insurance requires you to go to Labcorp or Quest for lab draws, then we can order through their platform.
