title: Clinical trial of a new disposable bleeding-time device.
abstract: A new disposable bleeding time device (Hemalet) was tested in 20 normal individuals and 11 patients with various bleeding disorders. The results were compared with those of Simplate II. The mean bleeding time for normal individuals was 5.4 +/- 1.5 (mean +/- 1 SD) minutes by Hemalet and 5.8 +/- 1.4 (mean +/- 1 SD) minutes by Simplate II, with good correlation between the results by the two devices (r = 0.81). The bleeding time in patients with various bleeding disorders were also comparably prolonged between the two devices. The new disposable bleeding time device with a disposable blade has quick release (penetration) into skin and retraction, and offers an alternative means of a bleeding time test.
