title: A clinical evaluation of the QBCII centrifugal hematology analyzer in the emergency department.
abstract: As part of an effort to reduce patient waiting time for laboratory results, the QBCII desktop CBC analyzer was evaluated in an emergency department. CBCs were performed by the emergency department staff (multiple observers) on 498 patients and by a single observer on 250 patients. Time required by the emergency department staff to obtain a CBC was 10.1 minutes compared with 47.8 minutes for the hospital laboratory. Correlation coefficients between hospital laboratory and QBCII were WBC 0.94, hematocrit 0.92, platelets 0.88, lymphocytes/monocytes 0.92, and granulocytes 0.90.
