FIELD-EVALUATION OF THE NOVA CELLTRAK 12(R) HEMATOLOGY ANALYZER

An evaluation of the NOVA Celltrak 12 was performed over a 6-week peri od. Precision, linearity, carryover, and reproducibility of values com pared favorably to manufacturers' claims. The correlation was performe d using the Coulter S Plus VI as the reference instrument and yielded coefficients of correlation for measured parameters of greater than .9 8 with the exception of RDW at r = .84, MCV at r = 0.96, and MPV at r = .92. Three-part differential information and an expanded flagging sy stem affords increased clinical information and troubleshooting guides . The three-part differential information compared favorably with that of the Coulter S Plus VI with lymphocyte percentage r = .96, granuloc yte percentage r = .94, and monocyte percentage r = .50. We conclude t hat this instrument performed well in a clinical setting.
