The identification of malarial parasites and other blood parasites is used to determine treatment and prognosis. Babesia and other blood parasites are noted and reported. Microfilaria can be detected from a giemsa stain. However, this test is not recommended for the detection of microfilaria. One negative observation cannot rule out blood parasites.
Blood samples are to be taken, and slides prepared when the
patient presents with symptoms of malaria, and every 6 hours
for 36 hours.
Specimens obtained during the febrile state yield the greatest number
of parasites in circulating blood. It is very important that at least
one thick and one thin blood film smear must be submitted on two
separated glass slides with one frosted end, in addition to the
EDTA (lavender-top) tube.
One slide should be smeared as is done with a differential exam
and one slide should have a drop of blood dried in an area about
the size of a dime.
Note: Travel history (name of country and when visited) and anti-
malarial agents should be noted on the requisition.
