Kotepui et al developed a decision tree for distinguishing malaria from dengue fever based on the results of a complete blood count (CBC). The authors are from Walailak University in Thailand.
Parameters:
(1) absolute neutrophil count per µL
(2) hemoglobin in g/dL
(3) absolute lymphocyte count per µL
(4) MCHC in g/dL
(5) gender
Findings
Diagnosis
absolute neutrophils >= 2,800 per µL
80% malaria
absolute neutrophils < 2,800 per µL; hemoglobin >= 11 g/dL
80% dengue
absolute neutrophils < 2,800 per µL; hemoglobin >= 11 g/dL; absolute lymphocyte count >= 800 per µL
