The Study of Platelet Volume Indices in Platelet Aphaeresis Procedure: An Experience Of 271 Platelet Aphaeresis Procedures

摘要

Background: Platelet activity can be assessed by platelet volume indices like MPV, PDW & P-LCR. Aim: To develop an approach in blood bank professional, a habit of looking at platelet indices in hematology analyzer report of aphaeresis donors & QC samples of platelet aphaeresis products. Methods and materials: A retrospective data analysis was done for 271 platelet aphaeresis procedures conducted on CS3000 plus with AMS cell separator, Fenwal, USA& COM.TEC, Fresenius Kabi, Germany. Samples of the donors were collected before aphaeresis & 1 to 2 ml sample from each bag was collected in the satellite pouch attached to bag & analysis was done on day 0 & day 7. Platelet parameters were measured on automated hematology analyzers SYSMEX KX-21 & Horiba Micros 60.Statistical analysis: Statistical analysis was done by calculating ?r value? & a paired t test at 95 % confidence interval. A P value of
