Testing for West Nile Virus – Forms and Instructions: Commercial tests to detect WNv and other arbovirus antibodies are readily available at most commercial laboratories. During 2009, GDPH recommends that diagnostic testing for human arbovirus infections be performed at commercial laboratories. The Georgia Public Health Laboratory (GPHL) can perform testing for serologic evidence of infection with each of the arboviruses that circulate in Georgia, but due to limited resources, specimens will not be tested by GPHL unless they meet the testing criteria. Please call the Georgia Department of Public Health (404-657-2588) or the appropriate District Health Office before submitting specimens for arboviral testing to assure that the criteria are met for testing at GPHL and all necessary forms are completed. If needed, specimens with positive results for WNv or other arboviruses at commercial laboratories can be confirmed at GPHL. Please do not submit specimens unless testing criteria are met; ineligible specimens will not be tested.
