BATON ROUGE, La. -- Baton Rouge General (BRG) has performed more than 1,500
antibody tests over the past 4 weeks and, as of today, 4.5% of those tests
came back positive. A positive test indicates that a person was likely
infected with COVID-19 and that their body has produced antibodies, specific
proteins which are made in response to infections.
The results also showed:
- While African Americans made up only 5% of test takers, 17% of positive
results came from African American patients.
- Only one positive test was from a person under 20 years old.
- Half of BRG’s positive tests have come from people between the ages of 40-59.
- Women are more likely to get tested than men, but they test positive at
the same rate.
There are many different types of antibody tests available, but BRG is
using the COR2G serology test developed by Mayo Clinic, which yields a
98.6% specificity (ability of the test to correctly identify those with
antibodies). The samples are sent to the Mayo Clinic Laboratory to analyze
for the presence of antibodies.
See illustration. Mayo Clinic’s test
specifically detects antibodies to SARS-CoV-2, the virus that causes COVID-19.
BRG began offering the tests in late April and now offers antibody testing
at most of its primary care and urgent care clinics.
Antibody testing is most useful for people who experienced symptoms of
COVID-19. Antibodies develop between eight and 14 days after the onset
of symptoms, so it’s best to wait at least 10 days after initial
symptom onset or 10 days after a known exposure to COVID-19 to be tested
for the most accurate result.
