Abstract

Objective:  To evaluate the performance of Sysmex KX – 21 for the estimation of Platelet and WBC count in comparison with microscopy.

Study Design:  It is prospective cohort study.

Place and Duration:  It was conducted in the Patho-logy department, Allama Iqbal Medical College, from 7^th Oct. 2009 to 6^th Nov. 2009.
