Abstract

Quality management and efficiency has been considered as an important issue in laboratory diagnosis As U S Food and Drug Administration (FDA) recommended coagulation analyzer should avoid substance interference before becoming a product In this study the effects of potential interferents on a novel portable optical-based coagulation detector were examined including hematocrit hemoglobin bilirubin triglyceride cation antibiotic heparin and polybrene The coagulation trigger tissue factor was coated on the chips by lyophilization which was reported to stress and disrupt the structure of the liposomes imposed during the process By using cryo-electron microscopy (cryo-EM) the structure of liposome was clearly visualized Besides lyophilization heat tolerance of the reagent was also accessed by cryo-EM morphology and PT functional measurement World Health Organization (WHO) quality management recommended that the supply and reagent inventory management system might facilitate the improvement of the efficiency and quality of diagnostic laboratories Taking advantage of network and mobile devices a new approach to manage the supply and reagent was established The study results included that (1) the addition of interferents might not affect the PT measurement; (2) the structure of liposome remained intact after lyophilization; (3) The PT reagent remained active after heating at 90?C for 30 minutes; (4) the rate of dissolving and the degree of mixing were the bottleneck for lyophilized-reagent chips to generate a detectable PT signal; (5) an application for real-time inventory management was invented with the application allowing managers to monitor the inventory real-timely in more convenience and efficient way
