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