Finger-prick tests are used only to detect antibodies and not to diagnose active coronavirus cases, they said.
"Only a test that uses a nasal swab or saliva should be used to diagnose active cases of COVID-19," the FBI Newark Field Office said in an alert Friday.
"If you were recently tested for COVID-19 at Infinity Diagnostic Laboratory, located at 6715 Atlantic Avenue, Ventnor, you are urged to be retested as soon as possible," the FBI wrote.
"Also, if you were tested using a finger prick blood test at that location, please contact the FBI at NK-Victim-Assistance@FBI.gov.
"Your response is voluntary but would be useful in a federal investigation," the alert says. "Based on the response provided, you may be contacted by the FBI and asked to provide additional information."
