Specimen Instructions:
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.
Turn Around Time:
1-5 days upon receipt at reference laboratory.
Reference Range:
0.79 IV or less: Negative - No significant level of detectable E. histolytica IgG antibody. 0.80-1.19 IV: Equivocal - Repeat testing in 10-14 days may be helpful. 1.20 IV or greater: Positive - IgG antibody to E. histolytica detected, suggestive of a 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.

Note: In the case of extraintestinal complications, a positive antibody can indicate amebiasis even though stool findings are negative.
Methodology:
Semi-Quantitative Enzyme-Linked Immunosorbent Assay
