Worksheet 1: Calculating SDI and CVI 1210 Effective Date: 12/6/2016 HILS1746 1. Calculate the CVI for each control. 2. Calculate the SDI for each control. Platelet Count (cells x 109/L) Sysmex XE- Low Control Normal Control High Control 2100 Your Lab Mean 56 214 545 SD 17 37 CV 10.7 7.9 6.8 My Lab (Peer) CVI My Lab (Peer) SDI Peer Group Mean 62 215 496 SD 19 40 CV 11.3 8.8 8.1 Z 12 12 12 3. Calculate the TE for each control. TE in units of cells x 109/L 4. If the criterion for acceptable performance for platelet count is 25%, is the TE acceptable? TEA in units of cells x 109/L TE < TEA 129
