Microscopy for Ova, Cysts and Parasites (OCP) is only routinely performed on specimens from patients with a history of foreign travel (within 6 weeks). If testing is required outside of this window for other reasons (e.g. patient is immunocompromised) please contact the laboratory via email (rduh.MicroConsultants@nhs.net) to discuss with a consultant microbiologist.
We DO NOT perform OCP on samples from patients with a travel history limited to Europe.
Please state OCP on request form (ova, cysts and parasites).
Enterobius vermicularis (threadworm) – please send moistened early morning perianal swab – place in specimen pot rather than in transport media (NB we do not accept sellotape slides).
