About Entamoeba histolytica IgG Antibody (Amoebiasis) – Serum
The Entamoeba histolytica IgG antibody - serum test is used to detect antibodies to the parasite Entamoeba histolytica in the blood sample. If someone has been infected with E. histolytica, their immune system may generate these IgG antibodies. E. histolytica is a parasite that primarily infects the gastrointestinal tract and, occasionally, other tissues. It is commonly found in tropical regions with inadequate sanitation and hygiene practices, particularly affecting children under the age of five. This test may be necessary if individuals are experiencing symptoms associated with amoebiasis.
Thus, it is recommended to undergo this test for the diagnosis of amoebiasis and to promptly initiate treatment.
Symptoms of amoebiasis
-
Bloody diarrhea
-
Abdominal pain
-
Nausea and vomiting
-
Fever
-

Interpretation of Results
Test results can differ based on factors such as age, gender, medical background, diagnostic laboratory, and various other variables.
The interpretation of the test results is as follows:
8 U or less: Negative - There is no significant detectable level of E. histolytica IgG antibody.
9 - 11 U: Equivocal – It is recommended to carry out testing again after 10-14 days.
12 U or greater: Positive - The presence of IgG antibody to E. histolytica indicates the possibility of either a recent or past infection.
FAQs on Entamoeba histolytica IgG Antibody (Amoebiasis) – Serum
A healthcare provider will draw a small blood sample from a vein in your arm using a needle. The blood will be collected in a test tube or vial and sent to the lab for analysis.
There are no known risks associated with this test. During a blood test, one may experience minor pain or bruising where the needle was inserted, but most symptoms will subside quickly.
The test result is usually available within 4 days after the sample collection. This duration may vary depending on the diagnostic clinic.
After developing IgG antibodies to E. histolytica, they can persist in your bloodstream even after the amebiasis has cleared. Therefore, a positive antibody test result might indicate past exposure to the parasite rather than a current infection.
The transmission of amoebiasis occurs when individuals consume food or water that has been contaminated with fecal matter from someone infected with the E. histolytica parasite.
