| Test Mnemonic: CYST CSF | |
|
Methodology: Enzyme-Linked Immunosorbent Assay
Performed: Tue, Fri Reported: 1-5 days |
| Specimen Required: | |
|
Collect: CSF.
Transport: 1 mL CSF at 2-8°C. (Min: 0.5 mL) Submit specimen in an ARUP Standard Transport Tube. Pediatric Collection/Transport: 0.2 mL CSF at 2-8°C. Unacceptable Conditions: Serum.

|
| 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.
