What Test Should Be Done To Detect Tapeworm Infection?
Thank you for posting your query.
First of all, I would like to reassure you that there are very little chances of the tapeworm infection being invasive in your case, as you have seen the worm pass out in the stool.
If it becomes invasive, there are three common areas where they infect- brain, muscles (of thighs) and extra ocular muscles (around the eyeballs). The common symptoms would be headache/fits, pain in thighs, limited eye movements respectively. If you do not have any symptoms then most likely you do not have the invasive tapeworm infection.
Blood tests that are helpful are- high eosinophils count in the blood and anti-cysticercal antibody test (ELISA).
For actually seeing the cystic or other stages of invasive tapeworm, tests that are useful are MRI of brain and orbits (to detect tapeworms in brain and eye muscles) and ultrasound or X-ray of thighs.
I hope it helps. Please get back if you have any more queries.
Best wishes,

Thank you for getting back.
There is no specific blood test to determine the cystic stage of tapeworm. However, if someone has a specifc body part affected (such as brain, eye muscles or thigh muscles), the cysts can be seen on the MRI of that area.
Anti-cysticercal antibody ELISA test can be done on a blood test and you have to ask for this specifically (however, again it is not a highly specific test).
Eosinophil count can be checked in a routine blood test.
Involvement of other organs is rare, and may happen in those who are immuno-compromised (such as HIV infection, diabetes, those on steroids, etc).
I hope it clarifies.
