Detection of cytomegalovirus from blood leukocytes separated by sepracell-MN and Ficoll-Paque/Macrodex methods.


Two density gradient separation techniques for separation of blood leukocytes were compared for the laboratory diagnosis of cytomegalovirus (CMV) viremia. Of 510 blood specimens processed by both methods, 76 (14.9%) yielded CMV. Of the 76 positive specimens, 66 (87%) and 65 (86%) were processed by the Ficoll-Paque/Macrodex (F-P/M; Macrodex is dextran 70 in… (More)
