Special Instructions

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).
