Viral testing is critical to containing the COVID-19 pandemic, and returning to our jobs and our community. We have been receiving many requests for information about testing — especially antibody testing — and are pleased to be offering this as of Tuesday, April 28. Click here to book.
As there is a lot of misinformation circulating, it’s important to understand what the available testing can and can’t tell you.
PCR testing — For current infection
Like a DNA test for a virus.
The PCR test is a swab used to detect the RNA of the virus. This is like a DNA test for a virus. It is quite sensitive and is an excellent way to tell if you have a current infection.
A negative test result means you most likely don’t have an active infection. If the swabbing is not handled accurately, you can get a false negative result.
A positive test result means you almost certainly have an active infection, or have recovered very recently.
Antibody testing — For past infection
Not a test for immunity (yet).
This is a blood test that detects antibodies that you may have produced when you were exposed to the COVID-19 virus. It works best if you wait 14 days or more after symptoms.
A negative result means you probably have not been exposed to the virus.
Because of the high possibility of false positives, a positive result will be communicated to you by a Circle Medical provider, who will help interpret it.
Keep in mind:
If you’d like to be tested, please book a COVID test appointment with Circle Medical. A provider will assess you and order the appropriate test.
