Higher rates among those under 20 years old, hospital staff

BATON ROUGE, La. -- Baton Rouge General (BRG) has performed more than 3,600 antibody tests and, as of today, 5.5% 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. This is an increase from a 4.5% positive rate in May.

The results also showed:

  • While those under 20 years old made up only 1.7% of test takers, 8% of positive tests came from patients under 20.
  • Among BRG employees, there is an 8% positive rate.
  • While African Americans made up only 9% of test takers, 16% of positive results came from African American patients.

Antibody testing is most useful for people who experienced symptoms of COVID-19. Antibodies develop between anywhere from 1-3 weeks 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.

BRG began offering antibody tests in late April and offers them at most of its primary care and urgent care clinics. For more information on BRG’s antibody testing, click here.
