A questionnaire survey of current practice in the bleeding time test has been undertaken by the UK External Quality Assessment Scheme in blood coagulation. Completed returns have been received from 358 centres. Most centres (88.5%) perform bleeding times and of these the Ivy test is the most commonly performed. Only 13.6% perform the Duke method. Templates are used to control the procedure by approximately half of the hospitals. There is considerable variability in the type and depth of incision and interpretation of the endpoint. The upper limit of normality not unexpectedly differs considerably between the centres with both Ivy and Duke methods. The use of a commercial template method, 'Simplate', provides a measure of agreement amongst the group of hospitals using this instrument but it remains to be established whether this is the most reliable procedure. In the interim, gross discrepancies in technique or interpretation should be corrected in the light of the findings of the survey.
英国血液凝固外部质量评估计划对出血时间测试的当前实践进行了问卷调查。已收到358个中心的完整回复。大多数中心（88.5%）进行出血时间测试，其中常采用Ivy测试法。只有13.6%的中心采用Duke法。约一半的医院使用模板来控制操作过程。切口的类型、深度以及终点的判定存在很大差异。不出所料，采用Ivy法和Duke法的各中心之间正常范围的上限差异很大。使用一种商业模板法“Simplate”，在使用该仪器的医院组中达成了一定程度的一致性，但这是否是最可靠的方法仍有待确定。在此期间，应根据调查结果纠正技术或判定方面的重大差异。
