Hi, Thanks for posting in HCM. Tapeworm infection is the infestation of the digestive tract by a species of parasitic cestodal flatworm called tapeworms. Six types of tapeworms are known to infect people. They are usually identified by the animals they come from - for example, Taenia saginata from beef, Taenia solium from pork, and Diphyllobothrium latum from fish. To diagnose a tapeworm infection, the following needs to be done: 1. Stool sample analysis by microscopic identification for eggs or tapeworm segments. It may require 2 to 3 stool analysis done regularly to look for the tapeworm infestation. 2. Blood test to detect antibodies your body may have produced to fight tapeworm infection. 3. Imaging studies such as CT or MRI scans, X-rays, or ultrasounds of cysts, may suggest invasive tapeworm infection. Hope the information provided would be helpful. All the best.
