Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Tapeworm infection is a parasitic infection caused by various species of flatworms that live in the intestinal tract. These infections can cause abdominal discomfort, weight loss, and nutritional deficiencies. Accurate diagnosis requires specific testing to detect the presence of the parasite.
Recommended Test
Ova & Parasites w/Giardia Antigen (Stool)
This comprehensive stool test is designed to detect various parasites, including tapeworms. The test can identify tapeworm eggs and segments (proglottids) that are shed in the stool, providing direct evidence of an active tapeworm infection. This is the primary diagnostic method for confirming the presence of intestinal tapeworms.

Diagnosing Tapeworm Infection
While tapeworm symptoms can be subtle or mimic other digestive conditions, definitive diagnosis relies on laboratory testing that can directly identify the parasite or its components. This ensures appropriate antiparasitic treatment can be prescribed to eliminate the infection.
Understanding Test Results
A positive result indicates the presence of tapeworm eggs or segments in the stool sample, confirming an active infection. The test may also identify the specific species of tapeworm, which helps guide appropriate treatment. Multiple stool samples may be recommended to increase detection accuracy, as parasite shedding can be intermittent.
