CYSTICERCOSIS AB IGG - CSF

LAB1083

Collect

CSF.

Specimen Preparation

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

Unacceptable Conditions

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

Storage/Transport Temperature

Refrigerated.

Stability (from collection to initiation)

Ambient: 24 hours; Refrigerated: 2 weeks; Frozen: 1 year (avoid repeated freeze/thaw cycles)

Performed

Mon

Methodology

Semi-Quantitative Enzyme-Linked Immunosorbent Assay

Reported

1-8 days

Synonyms

  • Taenia solium Antibody IgG (CSF) by ELISA
  • LAB1083

Ordering Recommendations

Detect the presence of CSF IgG antibodies to T. solium, if clinical suspicion of cysticercosis exists. Confirm positive results with IgG Western blot antibody test.

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.

CYSTICERCOSIS AB IGG -SERUM

LAB1082

Collect

Serum separator tube.

Specimen Preparation

Transfer 1 mL serum to an ARUP Standard Transport Tube. (Min: 0.1 mL) Parallel testing is preferred and convalescent specimens must be received within 30 days from receipt of the acute specimens. Mark specimens plainly as acute or convalescent.

Unacceptable Conditions

CSF. Contaminated, heat-inactivated, hemolyzed, icteric, or lipemic specimens.

Storage/Transport Temperature

Refrigerated.

Stability (from collection to initiation)

After separation from cells: Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 year (avoid repeated freeze/thaw cycles)

Performed

Mon

Methodology

Semi-Quantitative Enzyme-Linked Immunosorbent Assay

Reported

Synonyms

  • Taenia solium Antibody IgG by ELISA
  • LAB1082
  • CYST S

Ordering Recommendations

Detect presence of IgG antibodies to T. solium in serum if clinical suspicion of cysticercosis exists.

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 antibody detected.  Repeat testing in 10-14 days may be helpful.
0.51 O.D. or greater: Positive -  IgG antibody to cysticercosis detected suggestive of current or past infection.

Interpretive Data

Seroconversion between acute and convalescent sera is considered strong evidence of recent infection. The best evidence for infection is a significant change on two appropriately timed specimens where both tests are done in the same laboratory at the same time.

Patients with collagen vascular diseases, hepatic cirrhosis, schistosomiasis, and other parasitic infections can produce false-positive results. There is a strong cross-reaction between cysticercosis and echinococcosis positive sera. Confirmation of positive ELISA results by the cysticercosis antibody, IgG by Western blot is recommended.
