Malaria Screening and Confirmation

Description: 
Initial malaria screen by blood film and fluorescent microscopy examinations in order to assess presence of malarial parasites in peripheral blood.
Confirmatory follow up tests are performed using immunochromogenic technology and thick and thin films, which help identify the species. Parasite counts are reported for P. falciparum.
Final report and confirmation is made by lead Microbiologist.

A negative screening result does not exclude malaria. If clinically indicated, a repeat test should be performed.

Request must include recent travel history.
Due to recent concerns regarding VHF the laboratory cannot proceed with testing until information on travel history is received, this may delay testing if not received with initial request.
