Western Equine Encephalitis Antibody, IgG by IFA, CSF : 0098897

Mnemonic: WEST G 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 or heat-inactivated specimens.

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