As the nation’s leading respiratory hospital, we are committed to helping businesses keep their employees safe. Our Advanced Diagnostic Laboratories have developed COVID-19 tests that identify people who actively have COVID-19 or who have built antibodies to the SARS-CoV-2 virus.
We also help businesses who need help developing a return-to-work pandemic strategy that meets regulatory and public health standards and, most importantly, keeps everyone safe. Visit Return-to-Work Services for more information.
We know how important it is to identify if an employee has COVID-19 or has the antibodies. Test results are available within 24-48 hours of order processing.
All of our COVID-19 tests are approved or have a pending application for emergency use authorization (EUA) from the Food and Drug Administration (FDA).
The molecular diagnostic test is the most widely used diagnostic test to determine active disease for COVID-19. A nasal swab is used to collect a sample. It detects genetic material from the SARS-CoV-2 virus. A positive molecular test indicates that a person has SARS-CoV-2 viral particles in the airways and has COVID-19 disease. A person with a positive molecular test should be considered infectious to other people and should self-isolate.
IgM is the first antibody produced by the immune system. A positive IgM test indicates that a person has been infected and has begun to mount have an immune response to the virus. IgM antibodies disappear soon after the virus has been cleared from the body. A person with a positive IgM test may still have an active infection and should self-isolate.
In most patients, IgG antibodies develop 7 to 10 days after symptoms of COVID-19 begin. The results of this test may indicate that a person has had COVID-19 in the recent past and has developed antibodies that may offer protection from future infection.
Antibodies can provide protection against re-infection, although strength of the protection and how long the protection may last varies by disease. People with antibodies may have a level of protection against SARS-CoV-2 re-infection, although researchers are still determining the level of protection.
