*8.2.2 Blood (serum)*

Serum samples are preferred for antibody-antigen diagnosis of cysticercosis serologically. Serodiagnostic assay recognized by the World Health Organization and the Pan American Health Organization for cysticercosis and neurocysticercosis outline in Lee et al. [21] in comparison to CSF uses both lentil lectin-purified glycoproteins (LLGP) in an enzyme-linked immunoelectrotransfer blot (EITB) format.

## *8.2.3 Tissue sampling*

Once eggs or proglottids are ingested, oncospheres hatch in the intestine invade the intestinal wall, enter the bloodstream, and migrate to multiple tissues and organs where they mature into cysticerci over several months. Definitive diagnosis consists of the demonstration of the cysticercus in human tissue affected by the larval *Taenia solium* cysts in tissue sections [22].
