REASONS OF DONOR DEFERRAL FOR A SINGLE DONOR PLATELETPHERESIS IN A PUBLIC SECTOR BLOOD TRANSFUSION CENTRE OF LAHORE: A CROSS-SECTIONAL STUDY

Background and Objective: Plateletpheresis is a process by which platelets are extracted from the donor. Donor selection is critical since donors are the sole supply of blood available to satisfy demand. The goal of this study is to investigate the causes behind plateletpheresis donor deferral in order to ensure safe blood donation. Materials and Methods: The research was carried out at the department of Haematology and Transfusion Medicine University of Child Health Sciences, The Children Hospital Lahore. 50 plateletpheresis donors who voluntarily came for donation were considered for the procedure as per guidelines and departmental standard operating procedure. The details of the procedure of plateletpheresis were explained to each donor. Donor questionnaire was filled including brief history, general physical examination, Haematological parameters such as haemoglobin and the donor blood screening was done to be considered fit for procedure. The reasons for deferral of donors were noted after all work up was done. Informed consent was taken before the procedure. Plateletpheresis was done using COM.TEC Cell Separator instrument. Results: In this study 50 donors were included. Out of 50 donors 34 were approved for procedure and 16 were deferred due to different temporary and permanent reasons. The age of the donors were in between 18 to 50 years. Major reason for temporary deferral was poor venous access (n=7, 14%) followed by the low haemoglobin value (n=4, 8%). Other reasons for temporary deferral were history of medication (n=3, 6%), low platelet count (n=4,8%), history of blood transfusion (n=1, 2%), history of vaccination n=2, 4%), leucocytosis (n=1, 2%), underweight (n=4, 8%), fever (n=1, 2%), refusal after questionnaire (n=1, 2%), seropositive for malaria and VDRL (n=3, 6%), high blood pressure (n=1, 2%), and anxiety (n=1, 2%). Permanent reasons for deferral were seropositive for HbsAg (n=2, 4%), seropositive for HCV (n=4, 8%) and tattoo (n=1, 2%). Conclusion: This study found a pattern of donor deferral in single donor platelet apheresis that was our experience in single centre.  In conclusion during the selection of donors, Transfusion services should be very careful related to donor safety measures and these causes of deferral should be kept in mind.
