Microscopy and antigen detection for malarial parasites can be performed on the same sample as the FBC sample. Please supply details of which countries the patient has visited along with prophylaxis or treatment details.
All malaria requests now incorporate the malaria antigen test in addition to microscopy.ails.
Blood films are stained at pH7.2 and stained with Giemsa and are viewed for the presence of malarial parasites.
WHO guidelines suggest three negative microscopy and antigen detectio. results in 72 hours to exclude malaria. In the event of a positive finding the clinician/ward will be informed. A percentage parasitaemia is only given in cases of Plasmodium Falciparum and Plasmodium Knowlesi.
Please note: negative films do not exclude a diagnosis of malaria blood films and should be repeated if clinically indicated. If there has been travel to the Asia-Pacific region and clinical indication, please repeat in 12-24 hours to rule out presence of Plasmodium Knowlesi.
This is an immuno-chromatographic test using monoclonal antibodies against the metabolic enzyme pLDH (parasite Lactate Dehydrogenase) of Plasmodium species.
There are two monoclonal antibodies used, one specific for Plasmodium (P) falciparum, and one pan-specific antibody that reacts with all four species found in humans:
P falciparum, P. ovale, P. vivax and P. malariae.
