Abstract
A statistical protocol for evaluating the need for duplicate coagulation testing was developed. It requires at least 32 sets of duplicate prothrombin times or partial thromboplastin times over the expected range of results. In addition to the statistical procedures, clinical evaluation of the duplicates is required.
