Time:
1-5 days upon receipt at reference laboratory.
Reference Range:
8 U or less: Negative - No significant level of detectable E. histolytica IgG antibody. 9-11 U: Equivocal - Repeat testing in 10-14 days may be helpful. 12 U 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.
