Two kinds of testing are used:
COVID-19 PCR tests and
antibody tests. The PCR test indicates if you have a current infection, while the antibody test indicates if you had a previous infection. These tests are administered according to
COVID-19 nasopharyngeal swab testing occurs when a health care provider determines that symptoms are such that testing is warranted. For example, testing may be ordered if you are exhibiting signs of fever with a temperature greater than 100 degrees, a new cough (within the last day or two) or shortness of breath that is not due to allergies or a chronic condition, and you are concerned that you may have been exposed to COVID-19. Testing also could occur to investigate something detected during a screening.
Testing involves checking a sample from your respiratory system by swabbing beyond the nose into the pharynx. It can take 1-2 days to receive results from the lab.
COVID-19 antibody testing (or serology testing) is used primarily for epidemiologic purposes to help determine how much of the U.S. population has been infected. Antibodies can be found in the blood of people who are tested after infection and can indicate if people have had an immune response to the infection.
We use antibody testing to identify potential convalescent plasma donors and support epidemiologic studies. This form of testing should not be used to diagnose COVID-19 or assess protective immunity.
CDC states that at this time, we do not know if antibodies make you immune to the virus.
All health insurance policies are required to provide coverage for the COVID-19 test. You will be asked to provide your insurance information at the time of your appointment. Uninsured patients will not be billed for COVID-19 testing. You may receive a bill from Marshfield Clinic Health System if your insurance information is not on file.
Following your COVID-19 test, your insurance provider may send you an explanation of benefits. An explanation of benefits is
not a bill.
The COVID-19 test is usually fully covered by your insurance provider. There are exceptions for some limited benefit plans.
Your insurance company also is required to pay the full cost of an office visit when a COVID-19 test is ordered or performed, specifically because of COVID-19 symptoms, exposure or diagnosis. Your insurance company is not required to pay for unrelated office visits where a COVID-19 test is ordered or performed.
If you have insurance and get a bill for your COVID-19 test, please call 1-888-258-9775 to speak to our customer service team.
If you don't have insurance, please confirm with us that you are uninsured when registering for the test. Testing and treatment costs will be billed to a federal uninsured program.
