What is a Serology test?

This type of test detects antibodies that show whether you have already recovered from a prior COVID-19 infection—even if you never had symptoms or felt sick. 

Who should get a Serology test?

Antibody testing is available only to patients who are not currently experiencing COVID-19 symptoms and have not experienced symptoms within 10 days. Common COVID-19 symptoms include fever, cough, and shortness of breath.

How accurate is the test?

At N3 Laboratories, we use Roche for Serology testing. The serology test has a specificity greater than 99.8% and sensitivity of 100% (14 Days post-PCR confirmation). The high specificity of the test is crucial to determine reliably if a person has been exposed to the virus and if the patient has developed antibodies.

How does the test work?

To conduct an antibody test for COVID-19, a health care professional from N3 Laboratories will take a blood sample, usually by drawing blood from a vein in your arm. Then the sample is tested in a lab to determine whether you’ve developed antibodies against the COVID-19 virus.

When will I get my results?

COVID-19 antibody test results may be ready within 48 hours.
