Cysticercosis Antibody, IgG by ELISA (CSF) : 0055285

Mnemonic: CYST CSF

Methodology: Semi-Quantitative Enzyme-Linked Immunosorbent Assay
Performed: Tue, Fri
Reported: 1-5 days
Specimen Required: Collect: CSF.

Specimen Preparation: Transfer 1 mL CSF to an ARUP Standard Transport Tube. (Min: 0.2 mL)

Storage/Transport Temperature: Refrigerated.

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

Stability (collection to initiation of testing): Ambient: 24 hours; Refrigerated: 2 weeks; Frozen: 1 year (avoid repeated freeze/thaw cycles)

Reference Interval:
0.34 O.D. or less: Negative - No significant level of cysticercosis IgG antibody detected.
0.35-0.50 O.D.: Equivocal - Questionable presence of cysticercosis IgG. Repeat testing in 10-14 days may be helpful.
0.51 O.D. or greater: Positive - IgG antibody to cysticercosis detected, which may suggest current or past infection.
Interpretive Data: Diagnosis of central nervous system infections can be accomplished by demonstrating the presence of intrathecally-produced specific antibody. Interpretation of results may be complicated by low antibody levels found in CSF, passive transfer of antibody from blood, and contamination via bloody taps.
