OBJECTIVE: The objectives of this study were to validate the Polymorphprep method for neutrophils isolation for conditions within an identified clinical laboratory setting and to confirm the purity and viability of isolated neutrophils utilizing standard clinical laboratory cell counting, differential, and viability methods. DESIGN: A validation study, utilizing a quantitative and qualitative design, was performed. PATIENTS/SAMPLES: 18 EDTA tube blood samples were collected from donors between the ages of 18-60, with no underlying condition. The study was performed in a CLS student laboratory of a midwestern university. The Institutional Review Board approved the study and informed consent was obtained from each subject before blood collection. INTERVENTIONS: Blood samples were treated using a Polymorphprep procedure to isolate a pure population of neutrophils. MAIN OUTCOME MEASURES: Pre and post cell counts were performed using an automated cell counter. Manual white cells differentials and Trypan blue white blood cells viability analysis was performed. RESULTS: The mean purity levels were at least 94% following isolation with Polymorphprep, the mean viability of neutrophils was 99%. CONCLUSION: The use of Polymorphprep technique provides a practical and effective method for the isolation of neutrophils from peripheral blood which can be used for investigative purposes. Validation of the purity of the isolated cell population can be readily confirmed using standard clinical laboratory cell counting and differential analysis. |
