Predictive value of low hemoglobin for the diagnosis of acute malaria
Abstract
Objective: To compare the predictive value of low hemoglobin in the diagnosis of acute malaria with peripheral blood smear positivity for malarial parasite.
Methods: A cross-sectional study was conducted at Fauji Foundation Hospital Rawalpindi from May 2010 to October 2010. A total of 355 patients having fever were selected. Diagnosis of malaria was confirmed by peripheral film examination. Hemoglobin count was done on automated haematology analyzer Sysmex XT-2000i. Detailed information regarding age, sex, hemoglobin levels, peripheral film positivity and true positive / true negative were analyzed on SPSS 10.
Results: Out of 355 patients 86 were smear positive for malaria. Among the malaria positive cases, anaemia was present in 59(69%) patients. For low hemoglobin, 60(20%) were true positive while 233(80%) were true negative.Â
Conclusion: Malaria is associated with significant hematological changes with moderate to high frequency of anaemia.
