Comparison of Automated and Semi-Automated Determination for Prothrombin Time
Keywords:
Prothrombin time, Automate, Clotting assayAbstract
Objective: To compare automated and semi-automated determination for clotting assay. Study Design: Descriptive study. Setting: Faculty of Medicine Chulalongkorn University. Methods: In each day of July 1999, determination for PT was performed using control pooled plasma reagent. All assay tests were determined by two methods-using automated and semi-automated machine.
Average values for PT in one month were calculated, compared then analyzed. Results: The average values by automated method were 12.25t0 48 seconds for PT. The average values by semi-automated method were 12.33320.58 seconds for PT. It revealed that there was no significant between PT values determined by both methods. Conclusion: The clotting assay results from automated and semi-automated methods are not significant different. Recommendation for using of semi-automated method to perform clotting assay tests in small setting is set.
