ABSTRACT
Objective To investigate the practical application values of copper sulfate method and hemocyte analyzer in blood do‐nation screening .Methods A total of 1 500 blood samples of donors were randomly collected and determined by using both copper sulfate method and hemocyte analyzer .Taking hemocyte analyzer as the reference method ,the sensitivity and specificity of copper sulfate method for detecting hemoglobin(Hb) were calculated .The overall detection rates of abnormal blood samples determinded by the two methods were calculated ,as well .Statistical comparisons were performed on the test data from both methods .Results A total of 29 donors(accounted for 1 .9% ) with unacceptable Hb value were found by using copper sulfate method .For all blood do‐nors ,the sensitivity and specificity of copper sulfate method for Hb screening before blood donation was 99 .7% and 82 .8% ,respec‐tively .And there were no statistically significant differences in sensitivity and specificity between the two methods for Hb estima‐tion(P>0 .05) .There were 336 donors with abnormal blood samples detected by using hemocyte analyzer .Taking hemocyte analy‐zer as the reference method ,only 8 .6% of donors with abnormal blood samples were screened out by using copper sulfate method . Conclusion The copper sulfate method could be used for Hb screening before blood donation .While because of its limitations ,such as relatively low specificity and inadequate screening items ,the hemocyte analyzer shoud be utilized before blood donation if the con‐ditions permit .
