Adjunct to other diagnostic tests (eg, imaging) for echinococcosis. Patient's travel history is necessary to aid in test interpretation.
- Patient Preparation
- Serum separator tube (SST).
- Specimen Preparation
- Separate serum from cells ASAP or within 2 hours of collection. Transfer 1 mL serum to an ARUP Standard Transport Tube. (Min: 0.15 mL) Parallel testing is preferred and convalescent specimens must be received within 30 days from receipt of acute specimens. Mark specimens plainly as acute or convalescent.
- Storage/Transport Temperature
- Unacceptable Conditions
- Contaminated or severely lipemic specimens.
- After separation from cells: Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 year (avoid repeated freeze/thaw cycles)
0.90-1.09 IV: Equivocal - Questionable presence of Echinococcus IgG antibody detected. Repeat testing in 10-14 days may be helpful.
1.10 IV or greater: Positive - Presence of IgG antibody to Echinococcus detected, suggestive of current or past infection.
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.
