Author(s): Guracha E, Tsegaye A and Negash M*
Background: Copper sulphate (CuSO4) gravimetric haemoglobin screening method has been found to erroneously include anaemic people while excluding eligible ones. Determining the rate of false deferral and false pass of prospective blood donors by this obsolete test, the routine screening method in the blood banks of Ethiopia, is the focus of this study. Methods: In this cross- sectional study capillary and venous blood samples from 422 voluntary donors at Hossana blood bank was analyzed by copper sulphate gravimetric test and automated hematology analyzer. Data was entered in Epi-Data 3.1 and analyzed by SPSS 20. P value less than 0.05 was considered as statistically significant. Agreement between the two methods was determined using the Kappa coefficient. Results: Overall deferral rate by the reference method was 2.. View more»
