Historically, the template bleeding time was a test used to help diagnose vWD. However, this test is subject to wide variation and, with the availability of tests that provide more specific results, is not currently essential for making the diagnosis.

A prolonged bleeding time is not specific for vWD and does not help to predict whether patients without a bleeding disorder will have problematic bleeding during surgery. The test is difficult to perform, and results are difficult to confirm (ie, poor reproducibility); results frequently are normal in patients with vWD type I.
