Assessment of pre and post donation changes in hematological parameters and serum calcium and magnesium levels in plateletpheresis donors.

Abstract

Background:Single donor platelet products are preferred over random donor platelet products due to several advantages. However, safety issues with regard to post procedure hematological decrements and serum calcium and magnesium levels in donors undergoing plateletpheresis have been explored minimally.Aims:This prospective study was done to analyze the effects of plateletpheresis on donor’s hematological parameters and serum calcium and magnesium levels.Settings and Design:It is a prospective, cross-sectional study conducted in the department of immunohematology and blood transfusion.Material and Methods:This study was undertaken on 150 healthy plateletpheresis donors over a period of 1 year. Blood samples were collected from each donor before and after the procedure, one in ethylenediaminetetraacetic acid (EDTA) vial for estimation of hematological parameters and another in plain vial for serum calcium and magnesium levels.Statistical Analysis Used:Paired t-test was used to analyze the data.Results:This study included donors in the age group of 18 to 60 years who underwent plateletpheresis on Haemonetics model of a machine (MCS) + intermittent flow cell separator. A statistically significant increase was observed in mean post procedural Hb (0.95%), Hct (0.7%), and red blood cell (RBC) count (1.3%). There was a decrease in mean post procedural platelet count (27.5%), white blood cell (WBC) count (4.02%), mean serum calcium (1.5%), and serum magnesium (5.1%), which was statistically highly significant (P < 0.001). No significant change was observed in post procedural mean platelet volume (MPV) and platelet distribution width (PDW).Conclusion:Amid the need of increased demand for plateletpheresis, donor safety must be ensured. Failing to do so can be detrimental to blood supply chain, hence stringent programs for post donation screening of plateletpheresis donors need to be established.
