Amoebiasis is an intestinal infection that causes diarrhea, abdominal pain, and potentially severe complications. It is caused by the parasite Entamoeba histolytica, which is transmitted through contaminated food or water. The Ova & Parasites with Giardia Antigen stool test is the most important test for diagnosis because it directly detects the parasite in stool samples.

Amoebiasis is caused by the parasite Entamoeba histolytica, which infects the intestines after you ingest microscopic cysts through contaminated food or water. The parasite is most commonly transmitted in areas with poor sanitation, but outbreaks can occur anywhere when food handlers or water sources become contaminated. Once ingested, the cysts travel to your intestines where they release active parasites that attach to the intestinal wall, causing inflammation, ulcers, and the characteristic bloody diarrhea associated with amoebic dysentery.
The Ova & Parasites with Giardia Antigen stool test is the most important test for amoebiasis because it directly detects Entamoeba histolytica parasites and their eggs in your stool sample. This comprehensive test examines multiple stool specimens under a microscope to identify the characteristic four-nucleated cysts or active trophozoites that confirm infection. The test is essential because amoebiasis symptoms can mimic other gastrointestinal infections like bacterial dysentery or inflammatory bowel disease, and only microscopic examination can definitively identify the specific parasite responsible for your symptoms. Early detection through stool testing allows your doctor to prescribe the appropriate antiparasitic medications before the infection spreads beyond your intestines to cause liver abscesses or other serious complications.
You should get tested if you develop persistent diarrhea (especially bloody or mucus-filled stools), severe abdominal cramping, or fever after traveling to areas with poor sanitation or drinking untreated water. Testing is particularly important if your symptoms last more than a few days, if you notice weight loss or fatigue, or if you have right upper abdominal pain that could indicate a liver abscess. You should also consider testing if you live in close quarters with someone diagnosed with amoebiasis, work in food service after potential exposure, or have a weakened immune system that makes you more susceptible to severe complications.
