Specimen Requirements
| Fasting Required | Specimen Type | Preferred Container/Tube | Acceptable Container/Tube | Specimen Volume | Specimen Minimum Volume (allows for 1 repeat) |
Pediatric Minimum Volume (no repeat) |
|---|---|---|---|---|---|---|
| No | CSF | Sterile Container/Tube | 3.0 mL | 2.0 mL | ||
| No | Serum | Red Top Tube (RTT) | Serum Separator Tube (SST) | 3.0 mL | 1.0 mL |
Collection/Processing Instructions
PROVIDE ONSET DATE, TRAVEL HISTORY AND SYMPTOMS. Specimens should be collected in the acute phase of illness. Store and transport to WSLH at 2-8° Celsius (refrigerated with cool packs).
If submitting CSF, a serum sample must also be sent for the same testing. Order two ARBOMSO tests, one for CSF and one for serum. Testing will not be performed if only CSF is submitted. Must collect serum sample within 48 hours of CSF sample collection. Alternatively, serum may be submitted by itself. Indicate on sample and order if the sample is CSF or serum.

Test Components
Qualitative IgM testing for Eastern Equine Encephalitis, St. Louis Encephalitis, La Crosse Encephalitis, West Nile Virus, Jamestown Canyon Virus and Powassan Virus.
Test Information
Laboratory regulations require the following minimum information to be provided on the requisition form for a specimen to be accepted for testing: Patient name or unique identifier; date and time of collection, patient date of birth and sex, specimen type/site of collection, test request(s), clinician name and UPIN, and address for reporting results. Please be certain that name/identifier on the form matches that on the specimen label.
Interferences
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.
Interpretations
Negative, Presumptive Positive or Nonspecific for MIA assay.
Numeric value and interpretation as Negative, Equivocal, Presumptive Positive or Non-Specific for IgM capture ELISA.
