Entamoeba Histolytica IgG Test

What is the Entamoeba Histolytica IgG test?

The Entamoeba Histolytica IgG test detects IgG antibodies in the blood against the parasite Entamoeba histolytica, which causes the disease amebiasis. This test helps identify current or past invasive infection, especially extraintestinal amebiasis such as amoebic liver abscess. It uses a semi-quantitative Enzyme-Linked Immunosorbent Assay (ELISA) method.

Indications of the Test

This test is mainly ordered when there are symptoms such as fever, abdominal pain, or suspicion of extraintestinal amebiasis. It is useful for diagnosing invasive amebiasis when stool tests may be negative, especially for liver abscess cases.

Patient Preparation/Instructions

No special preparation is needed before the test. A blood sample (serum) is collected using a standard blood collection tube.

Typical Reference Values

• Negative: 8 U or less (no significant antibodies detected)

• Equivocal: 9-11 U (may require repeat testing)

• Positive: 12 U or greater (suggests current or past infection

Results typically take between 1 to 8 days after sample collection, depending on the laboratory schedule.
