Parascreen as an alternative diagnostic tool for falciparum malaria
Abstract
Background Malaria is a parasitic disease with high morbidityand mortality. Rapid immunochromatographic are emerging to
detect specific antigens of human plasmodia.
Objective To determine the sensitivity and specificity ofParascreen
for the detection of Plasmodium falciparum in children.
Methods A diagnostic test study was performed in Mandailing
Natal District, Penyabungan, North Sumatera. Subjects were
public health center and hospital patients with symptoms of fever,
pallor, headache, and diarrhea. Blood specimens were obtained for
Parascreen testing. Microscopy of Giemsa-stained blood samples
served as the gold standard.
Results One hundred and four subjects were studied. The sensitiv-
ity and specificity ofParascreen were 76% and 100%, respectively.
Positive and negative predictive values of the test were 100% and
49%, respectively. Likelihood ratio was infinite for a positive test
and 0.23% for a negative test.
Conclusion Parascreen is a useful and highly specific di-
agnostic tool for P. falciparum malaria
