RESEARCH OF PRODUCTION PROCESS AND EVALUATION OF HOMOGENEITY AND STABILITY IN LYOPHILIZED PLASMA APPLIED OF PROTHROMBIN TIME FOR COAGULATION LABORATORY EXTERNAL QUALITY ASSESSMENT
Main Article Content
Abstract
Objective: Development of the production process of lyophilized plasma-containing Prothrombin Time. Evaluation of homogeneity and stability of samples after production according to ISO 13528:2015 and ISO guide 35 for coagulation laboratory external quality assessment. Methods: Experimental study on the production process of lyophilized plasma-containing Prothrombin. The fresh frozen plasma is collected from Blood Transfusion Hematology Hospital - Ho Chi Minh City, Vietnam and tested negative for HBV, HCV, and HIV,... Adjust Prothrombin Time levels as desired. Evaluate the homogeneity and stability of lyophilized plasma by an average comparison test (Oneway ANOVA) and t-test. Results: The lyophilized plasma-containing Prothrombin Time in post-production batches under transport conditions were achieve homogeneity and stability for a minimum of 7 days. Samples are stable under storage conditions of -20oC and 2 – 8oC for a minimum of 10 weeks. Conclusion: The Quality control center of the medical laboratory of the University of Medicine and Pharmacy at Ho Chi Minh City (QCCUMP) has produced Prothrombin Time lyophilized from fresh frozen plasma with minimum stability of 10 weeks. Production samples that achieve homogeneity and stability according to the criteria of ISO 13528:2015 and ISO guide 35 meet the proficiency testing scheme
