What is SAR-CoV-2 Antibody Testing?

SAR-CoV-2 is the disease that causes COVID-19. This testing is obtained through one vial of blood sent to the laboratory to identify individuals, who have been exposed to the virus. This test has been authorized only for detecting the presence of antibodies against SAR-CoV-2, not for any other viruses or pathogens.

What antibodies are we testing for?


What are IgG antibodies and how do they relate to the virus?

IgG are the antibodies your body produces during the late stage infection and remain in your body long after the infection has subsided.

When should I get the test?

This test should be conducted 7-10 days after the first onset of symptoms. An antibody test does not diagnose a current infection. It only indicates if you have been exposed to the virus and your body has produced antibodies as a response. We do not know yet if having antibodies to the virus can protect someone from getting infected with the virus again, or how long that protection might last.

What is the specificity and sensitivity of this test?

This test has a 99.9% specificity and 100% sensitivity rate.

Who is the manufacturer of this antibody test?

Blood is sent to LabCorp and testing is completed using a test manufactured by Abbott Molecular Alinity m. Abbott is a global healthcare leader in infectious disease testing.

Is this test approved by the FDA?

On May 11, 2020, the U.S. FDA issued Emergency Use Authorization (EUA) for the company’s SARS-CoV-2 IgG lab-based serology blood test. This test has not been approved, but has been authorized for use by the FDA. This test should not be used as the sole basis to diagnose or exclude SARS-CoV-2 infection or to inform infection status.

Further information regarding FDA authorization and EUA listing can be found at the following websites:



What is the turn around time from the lab?

3-5 Business Days

Does a positive antibody test mean I am immune?

We do not yet know if a positive test result means that a person is immune, and if it does, for how long immunity might last. We hope to learn more about these questions in the coming months. If your test is positive, you should continue to follow public health recommendations on social and physical distancing, hand hygiene, environmental cleaning, staying home when ill and mask use.

What is the cost of this test?

In our Casper, Cheyenne, Laramie, Torrington & Scottsbluff offices this screening is $75.
At all other WHF locations the price for this screening is $77.

Please note:
Results from antibody testing should not be used as the solid basis to diagnose or exclude acute SAR-CoV-2 infection.
