Coronavirus Antibody Testing

SARS-CoV-2 IgM/IgG Blood Test


Minimizing the Spread

The severity of COVID-19 varies wildly within the population and you may be wondering if you've already been exposed to it. It's quite possible for someone to contract the COVID-19 virus but show mild or no symptoms. Our COVID-19 Antibody Test is designed to detect antibodies (called IgM and IgG) in the blood that are present when a person has been exposed to a virus in the past and built an immune defense against it. 

This simple blood test produces results in just 24-48 hours and is a critical tool in helping practitioners and health authorities understand the trajectory of the SARS-CoV-2 virus while minimizing its spread.

Have you developed antibodies to the COVID-19 virus? 

If you suspect you have been exposed to the virus and are interested in checking to see if you've developed antibodies so that you may return to work or visit loved onesthis test is right for you. 

Antibody testing gives some peace of mind in these unprecedented times.

Do you want to know if you are actively infected with the COVID-19 virus?

The antibody test does not necessarily tell you if you are currently infected but it will tell you if you have been infected in the past and are possibly immune to this virus, although the timing of active infections and antibody production can potentially overlap. 

If you are looking to confirm an active infection, please contact your local health department or healthcare provider to seek appropriate medical attention.

Why Choose SpectraCell's Antibody Test?

  • SpectraCell is a CLIA-certified lab which means it adheres to strict guidelines set forth by the Clinical Laboratory Improvement Amendment Act of 1988, which are United States federal regulatory standards set forth to ensure the quality of clinical lab testing.  
  • SpectraCell is experienced in immunoassay testing (the type of testing done for COVID-19 antibodies).
  • When this antibody test is measured against a reference material that is known to be positive for SARS-CoV-2 on a cohort of 113 samples, the data shows:

    For IgG - specificity = 100%, sensitivity = 97.2%
    For IgM - specificity = 100%, sensitivity = 87.9%

Important Information:

Because this virus has only recently come into existence, scientists are still learning about the human immune response to the disease. Although the presence of antibodies against SARS-CoV2 suggests immunity, it has not yet been proven. In addition, even in other viral diseases such as measles and chickenpox, for example, for which immunity after infection or a vaccine is well understood, there are still cases of people being re-infected with a viral disease for which they once had antibodies, as it is possible for immunity to be partial, or wane over extended periods of time.
Since the SARS-CoV2 virus is structurally similar to some other viruses, particularly those that cause respiratory symptoms, there is a small chance of a false positive test – i.e. the results can be positive even if the person has not had SARS-CoV2 virus but has built immunity to a different (but similarly shaped) virus.
This Coronavirus antibody test has been authorized by the FDA for Emergency Use.  Results from antibody testing should not be used as the sole basis to diagnose or exclude SARS-CoV-2 infection or to inform infection status.
If symptoms of a positive PCR test exists (testing issued by the CDC to determine active infections), the patient may want to consider follow-up testing after several days.
