Laboratory Evaluation of the Abbott Cell DYN 3500 5-Part Differential

TL;DRAbstract

The study reports the performance of the Abbott CD3500 automated hematology analyzer for the enumeration and delineation of leukocyte populations for both adult and pediatric samples, and the ability of this instrument to detect the presence of abnormal cells. Samples from 542 individual patients either attending medical practitioners or during hospitalization were examined and then subdivided for the purposes of this study into 106 samples from newborn infants (< days), 145 samples from older children (15 days to 14 years) with non-oncologic disorders, 100 samples from normal adults, and 191 samples from oncology patient (97 adults and 94 children). The leukocyte differentials provided by both the Abbott CD3500 and the Coulter STKS were compared with those obtained from conventional morphology (two observers, total of 400 leukocytes). The sensitivities and specificities of the blast, immature granulocyte (IG) and NRBC "flags" were also determined. For the non-oncology adult (n=100) an
