Diagnosing Trichuriasis
While trichuriasis can cause symptoms such as abdominal pain, diarrhea, and in severe cases, rectal prolapse, these symptoms can be similar to other digestive conditions. A definitive diagnosis relies on laboratory testing that can directly detect the presence of whipworm eggs (ova) in stool samples.
Understanding Test Results
A positive result indicates the presence of whipworm eggs in the stool, confirming trichuriasis. Treatment typically involves antiparasitic medications as prescribed by a healthcare provider. Follow-up testing may be recommended to ensure the infection has been successfully treated.
