A Non-invasive System for Predicting Hemoglobin (Hb) in Dengue Fever (DF) and Dengue Hemorrhagic Fever (DHiF)

摘要

Single frequency bioelectrical impedanceudanalysis (BIA) is an inexpensive, quick and painlessudmeans of estimating body composition. In this paper,udBIA parameters employed for predicting hemoglobinud(Hb) in dengue patients. The BIA technique passesudlow-amplitude electrical current, in the range of 500pAudto 800[A, at a single frequency of 50 kHz. BIA dataudwas sampled from 210 (comprises of 119 males and 91udfemales) serologically confirmed dengue fever (DF) anduddengue hemorrhagic fever (DHF) patients, hospitalizedudat the Hospital Universiti Kebangsaan Malaysiaud(HUKM). After applying multiple regression analysis,udwas found out that reactance, sex, weight and vomitingudwere found to be significant independent determinants ofudpredicting Hb.
