Bleeding time: Remained or Retired or Removed?

not require a skilled technician or expensive equipment [3]. However, it is an invasive test, and its reproducibility and the sensitivity to mild platelet function disorders is poor [3]. In addition, many preanalytical and analytical factors can affect the BT results [1, 4]. Consequently, most guidelines recommended discontinuation of BT, and the use of BT has rapidly declined and been replaced by other less invasive ex vivo platelet function assay [2, 5-8]. However, some laboratories still use the BT tests due to the clinical eld requirements [2]. In this article, the usefulness of the BT test for the evaluation of platelet function disorders and preoperative bleeding risk, and the characteristics and clinical utility of other platelet function tests that can be utilized for screening of platelet function defects will be brie y reviewed, and an ef cient way to use these tests will be suggested.
