Serodiagnosis of a recent infection with any of these agents in individuals with symptoms of arbovirus infection.
Testing will not be performed as a screening test or on patients without symptoms of WNV or SLE infection.
Red Top Tube (RTT) or
Serum Separator Tube (SST) or
1-3 mL serum or
8.5 mL SST vacutainer tube, no additives or
2 mL CSF
CSF MUST be accompanied by serum specimen.
Specimens should be collected in the acute phase of illness.
Specimens must be stored and transported to the lab at 2-8 degrees C (refrigerated/with coolpacks), and should be received within 48 hours of collection.
Cross-reaction may occur between the arboviruses. Negative results on a single acute phase specimen do not rule out infection, as specimen may have been obtained prior to the development of an antibody response
The MIA test methodology was developed at the CDC and validated at WSLH. It has not been cleared or approved by the U.S. Food and Drug Administration. Testing is performed twice weekly. Please contact the laboratory for information about out-of-season arbovirus testing.
