About Entamoeba Antigen, Stool
The Entamoeba antigen stool test is used to detect the antigen of the pathogenic E. histolytica in the stool sample. E. histolytica is a parasite that infects the gastrointestinal tract and sometimes other tissues. This parasite is commonly found in tropical regions with poor sanitation and hygiene practices, particularly affecting children under the age of five. This test may be necessary if individuals are experiencing symptoms of amoebiasis. Amoebiasis occurs when the parasite E. histolytica enters the digestive system, which can happen following consumption of contaminated water and food, especially via soil, fertilizers, and water contaminated with feces.
Thus, it is recommended to undergo this test for the diagnosis of amoebiasis and to promptly initiate treatment

FAQs on Entamoeba Antigen, Stool
For the Entamoeba antigen stool test, a stool sample is collected using a clean container. The patient is instructed to defecate directly into the container or to transfer a small portion of stool into it using the scoop provided.
The test result is usually available within 4-8 days after the sample collection. This duration may vary depending on the diagnostic clinic.
A limitation of the Entamoeba antigen stool test is that extraintestinal amoebiasis may be present even in the absence of trophozoites or cysts in the stool. This can lead to patients receiving a negative result for the Entamoeba antigen stool test even when they are infected with Entamoeba histolytica.
Amoebiasis can be prevented through consuming filtered or boiled water, ensuring the consumption of hygienic food, and maintaining proper sanitation practices. Practicing thorough handwashing with soap and water after using the toilet. Additionally, individuals diagnosed with amoebiasis should refrain from engaging in sexual contact until the infection has been treated and completely cleared.
Amoebiasis can be effectively treated through the use of antibiotics. However, in certain instances, individuals may require supplementary treatment, such as the provision of extra fluids.
