| WSLH Department: | CDD - Communicable Disease Division |
| WSLH Test Code: | SS02291 |
| Day(s) Performed: | Test is performed weekly |
| Turn-around Time: | 3-14 days |
| Recommended Uses: | Serodiagnosis of a recent infection with EEE in individuals with symptoms of arbovirus infection. |
| Contraindications: | Testing will not be performed as a screening test or on patients without symptoms of EEE infection. |
| Additional Tests Performed: |
| Patient Preparations: | Routine blood draw |
| Specimen Requirements: | 1-3 ml serum or 8.5 ml SST vacutainer tube, no additives; CSF, minimum 200 �l. CSF must be accompanied by serum specimen |
| Specimen Handling & Transport: | Specimens should be stored at 2-8 degrees C, transported with a frozen cool pack, and should be received within 48 hours of collection. If specimens will not be tested for 3 or more days, they should be frozen at -20�C until ready for shipment and shipped on dry ice. |
| Collection Kit/Container: |
Serology Specimens
Sterile Transfer Tube |
| Collection Instructions: | |
| Unacceptable Conditions: | Specimens received without cold packs or dry ice. Specimens collected post mortem are unacceptable for testing |
| Requisition Form: |
CDD Requisition Form B
|
| Required Information: | Clinical information regarding symptoms and onset must be provided. 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. |
| Results Include: | ** Negative: Test on single acute phase CSF or serum does not rule out infection. Lack of serological evidence of infection may reflect testing of acute phase specimen(s) obtained before development of an antibody response. ** Presumptive Positive: Serologic evidence for recent infection with Eastern Equine Encephalitis. ** Non-Specific: It is recommended that a serum specimen be collected in 2-3 weeks for follow-up testing. |
| Limitations: | Cross-reaction may occur between 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. |
| Additional Tests Recommended: | Enterovirus PCR, HSV, or other individual arboviral agents (LAC, WNV, POW, SLE) are also recommended. |
| Additional Comments: | 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 weekly. Specimens that test Presumptive Positive, or Non-Specific will be sent to the CDC for additional testing. |
| Methodology: | Microsphere Immunoassay (MIA) |
| Includes: | Qualitative IgM testing for Eastern Equine Encephalitis. |
