COVID-19 Testing 


We offer both molecular diagnostic and IgG antibody testing.

Molecular Diagnostic Test 

  • Performed with a nasopharyngeal swab.

  • Used to diagnose a current infection with SARS-CoV-2, the virus that causes COVID-19.

IgG Antibody (Serology) Test 

  • Performed with a blood draw.

  • Used to detect previous exposure to SARS-CoV-2 virus.

  • Test is most accurate after 14 days of being symptom free because this allows the body to develop antibodies.

  • Test is not used to diagnose current SARS-CoV-2 infection. If you test positive for antibodies, a confirmation molecular diagnostic test may be recommended to rule out current infection.

  • A positive test does not imply you have immunity to SARS-CoV-2 virus.

So When Should I Get Tested and How Does it Work?

You Currently Have Symptoms

If you're currently symptomatic with the following symptoms:

  • Body aches

  • Fatigue

  • Nasal congestion or runny nose

  • Chills

  • Fever

  • Sore throat

  • Cough

  • Headache

  • Shortness of breath

  • Diarrhea or vomiting

  • Loss of smell or taste

you should get tested via a molecular diagnostic test. We currently perform a nasal swab which is then sent to LabCorp or Quest. Due to the high demand for testing, results generally come back in 3-5 days, but can not be guaranteed.

  • A negative diagnostic test result means we could not detect SARS-CoV-2 virus in your nasopharynx. You should follow up with your PCP.

  • A positive diagnostic test result means you are currently infected with SARS-CoV-2 and you should continue self quarantine. 

You Currently Do Not Have Symptoms (Asymptomatic)

If you're asymptomatic, meaning you have no symptoms, for the last 14 days, we'll draw your blood to check for IgG antibodies to SARS-CoV-2, the virus that causes COVID-19. Your blood sample will be sent to LabCorp or Quest. Due to the high demand for testing, results generally come back in 3-5 days, but can not be guaranteed.

  • A negative antibody test result means that you have no antibody to the virus or the level of antibody present at the time of testing was below the test's detection limit.

  • A positive antibody test result means you may have been previously infected with the virus, and you may be required to get a confirmation molecular diagnostic test to rule out current infection. 

  • It's important to note that a positive result may be due to past or present infection with non-SARS-CoV-2 coronavirus strains.

  • Currently, there is not enough research or data to suggest that the presence of antibodies translates to immunity to SARS-CoV-2. In addition, we currently do not know how long the antibodies last after being infected with SARS-CoV-2. This could potentially mean even if you are immune to the virus, we're not sure how long immunity will last. We also do not know at what level of antibodies is required to produce sufficient immunity, if at all.

Discharge Instructions

If You are Asymptomatic and Have Not Been in Contact With a COVID-19 Positive Person and Would Like to Get Tested for Pre-Op, Return to Work or to Leave Isolation

Book online or call to schedule an appointment. Testing is available 5 days a week. Screening required. Appointment only.

Please expect a phone call from our front desk to complete your screening process prior to your appointment.

Cost for COVID-19 Related Visits and Testing

Please check with your insurance for COVID-19 related visit and testing coverage. Some insurances may not cover serology testing. Unfortunately, we do not take Kaiser insurance.

No Insurance

If you are uninsured, the cost for testing is $50 if you are asymptomatic and need to be tested for pre-ops, returning to work, etc.
