Lab Tests
When you see a health care provider about WNV symptoms, a sample of blood and, usually, cerebrospinal fluid may be sent to a laboratory to find out if you have the disease. The lab checks for antibodies to the virus (the body's response to infection). These antibodies can be measured in blood or cerebrospinal fluid, which surrounds the brain and spinal cord. This test is positive in most infected people within eight days after symptoms start.
A second test called the plaque reduction neutralization test (PRNT) may be done if the results from the first antibodies test are not clear. The results from the PRNT are often needed before the Centers for Disease Control and Prevention consider a human WNV infection confirmed.
