Background and Objectives: Quality control (QC) results of platelet-rich plasma and buffy coat-reduced platelet concentrates (PCs) are presented with the goal to assess their compliance with published guidelines and corrective action taken for any process deviation during their manufacture. Subjects and Methods: Retrospective QC of in-house prepared whole blood-derived platelets (2009–2013) was conducted. Their cumulative results were compared to the published quality standards given by the American Association of Blood Banks, Council of Europe, and Indian guidelines. Data was analyzed using SPSS Statistics version 20. Results: A total of 36,053 PCs were prepared during the study period, and 1.43% (n = 516) was subjected to QC. The aggregate five years mean ± standard deviation (range) of product per bag were volume 58.4 ± 9.5 (37–90) mL, platelet yield 5.89 ± 1.28 (3.1–8.7) × 1010, residual leukocyte count 1.5 ± 1.2 (0.02–5.5) × 107, pH 6.67 ± 0.48 (6.0–7.3), and erythrocyte contamination 0.29 ± 0.2 (0.03-2.0) mL. Swirling was present in all the units. None of the bags showed any microbial growth. Against volume, yield, and erythrocyte contamination 90.0%, 94.3%, and 87.0% units showed compliance to the Indian standards, respectively. All the PCs had pH and leukocyte counts well within the recommended norms. Conclusions: Quality of our platelet product although suboptimal to International standards was well within the national requirements.
