Mnemonic: EAST M CSF

Methodology: Semi-Quantitative Indirect Fluorescent Antibody
Performed: Tue, Fri
Reported: 1-5 days
Specimen Required: Collect: CSF.

Specimen Preparation: Transfer 2 mL CSF to an ARUP Standard Transport Tube. (Min: 0.15 mL)

Storage/Transport Temperature: Refrigerated.

Unacceptable Conditions: Contaminated, heat-inactivated, or hemolyzed specimens.

Stability (collection to initiation of testing): Ambient: 8 hours; Refrigerated: 2 weeks; Frozen: 1 year (avoid repeated freeze/thaw cycles)
Reference Interval:
Less than 1:1
Interpretive Data: This test is intended to be used as a semi-quantitative means of detecting eastern equine encephalitis virus-specific IgM in CSF samples in which there is a clinical suspicion of eastern equine encephalitis virus infection. A positive result for IgM may suggest current or recent infection. This test should not be used solely for quantitative purposes, nor should the results be used without correlation to clinical history or other data. Because other members of the Alphavirus family, such as western equine encephalitis virus, show extensive cross-reactivity with eastern equine encephalitis virus, serologic testing specific for these species should also be performed.
