Trichuriasis is a parasitic intestinal infection that affects millions of people worldwide, particularly in tropical regions with poor sanitation. It is caused by the whipworm Trichuris trichiura, which embeds itself in the colon and cecum after ingestion of contaminated food or water. The Ova & Parasites with Giardia Antigen (Stool) test is the most important test for diagnosis because it directly identifies whipworm eggs in stool samples.

Trichuriasis is caused by the parasitic whipworm Trichuris trichiura, which enters the body when you consume food or water contaminated with whipworm eggs. The eggs hatch in the small intestine, and the larvae migrate to the large intestine where they mature into adult worms that embed their whip-like front ends into the intestinal wall. This infection is most common in tropical and subtropical regions with inadequate sanitation, where human feces containing eggs can contaminate soil, water, and fresh produce.
The Ova & Parasites with Giardia Antigen (Stool) test is the most important test for trichuriasis because it directly detects Trichuris trichiura eggs in your stool samples. This comprehensive stool analysis uses microscopic examination to identify the characteristic barrel-shaped eggs with polar plugs that are unique to whipworms. The test requires multiple stool samples collected over different days to increase detection accuracy, as egg shedding can be intermittent. This same test also screens for other intestinal parasites and includes Giardia antigen detection, making it an excellent choice for comprehensive parasitic infection screening.
You should get tested if you experience persistent abdominal pain, chronic diarrhea (sometimes bloody), unexplained weight loss, or if you have recently traveled to tropical regions with poor sanitation. Testing is especially important if you develop rectal symptoms like tenesmus (feeling like you need to have a bowel movement even when your bowels are empty) or if children show signs of growth retardation or anemia. People who live in or have visited areas with inadequate sewage treatment or who consume food grown in soil fertilized with human waste should consider testing even without obvious symptoms.
