Amebiasis Antibodies
Also known as: E histolytica, Amebic Antibodies
Use
A positive test may not necessarily indicate active infection, since antibodies may persist for years. The titer is not directly correlated with the severity of the infection, due to the variance in patient response and to the variance in response to the type of infection. A negative response is equally important, as long as ample time has been allowed for antibody production.
Special Instructions
Not provided.
Limitations
Serology might show a positive result even in the absence of active infection due to lasting antibodies. Titers aren't correlated with the severity of infection, as responses vary across individuals and infection types. The test detects 90-100% of amebic liver abscess cases, 80-100% of symptomatic intestinal amebiasis, but only 10-50% in asymptomatic carriers.
