COVID-19 Testing

On Island COVID-19 testing is available to Clinic patients. There are basically two kinds of tests available: viral tests and antibody tests. A viral test tells you if you have a current infection. An antibody test might tell you if you had a past infection.

We currently offer COVID-19 testing with a saliva PCR test, a molecular test that detects the virus’s genetic material. This is a test for active infection. You perform the test at home and ship the sample via FedEx Express. Results are usually available in one to three days. We also have rapid antigen testing, which involves a nasal swab and tests for active infection. We perform the rapid tests in a designated area outside of the Annex building.

Remember, testing plays an important role in the overall approach to containing the virus. However, testing cannot replace the need to wear face coverings. When around others not in your household, keep a safe distance (at least six feet) while in public, avoid large gatherings (especially indoors) and wash your hands frequently.

COVID-19 Antibody Testing

The Clinic offers COVID-19 Antibody Testing through Quest Diagnostics. This test requires a blood draw and can give confirmation of a previous infection with COVID-19. Call our dedicated line at 941-964-0490 for more information and to schedule an appointment.

Gasparilla Island Wastewater COVID-19 Detection Testing Data

Gasparilla Island Wastewater COVID-19 Detection Testing Graph 03/14/2021 (continuing decline)

What does it mean?

The data points represent the concentration of 2 locations (N1 and N2) on the nucleocapside gene of SARS CoV2, the virus responsible for Covid-19 infections, that is detected each week in the wastewater of Gasparilla Island. Studies have shown that spikes of detectable virus concentration in the wastewater can precede detection of an increase of community cases of Covid-19 by 4-7 days. This data is monitored to assist with focusing testing, resources and education on preparation and precautions in the community.
