Evaluating Laboratory Centrifuges for Platelet-Poor Plasma Preparation: A Comparative Study of Performance and Usability

Executive Summary

This study compares two centrifuges, the Drucker Diagnostics DASH-4 and Beckman Coulter StatSpin® Express 2, for preparing platelet-poor plasma (PPP), which is essential for accurate diagnostic testing. Centrifugation is a critical step in stabilizing blood samples, and the quality of PPP directly impacts diagnostic accuracy.

Blood samples from 24 donors were processed using both centrifuges, and the results showed that both devices consistently produced PPP with platelet counts below 10 x103 platelets/μL, meeting clinical requirements. The performance of the DASH-4 and StatSpin® Express 2 was statistically equivalent, making both suitable for use in hospital laboratories.

Both centrifuges are compact, user-friendly, and comply with international safety standards, offering reliable performance for high-quality PPP preparation. This ensures that laboratory professionals can confidently use either device for accurate diagnostic results.
