Editing Bleeding time (section)

==Interpretation==
Bleeding time may be affected by platelet function, certain vascular disorders and [[von Willebrand Disease]]—not by other [[coagulation]] factors such as [[haemophilia]].  Diseases that may cause prolonged bleeding time include [[thrombocytopenia]], [[disseminated intravascular coagulation]] (DIC), [[Bernard-Soulier disease]], and [[Glanzmann's thrombasthenia]].<ref name="y378">{{cite journal | last1=Mehic | first1=Dino | last2=Assinger | first2=Alice | last3=Gebhart | first3=Johanna | title=Utility of Global Hemostatic Assays in Patients with Bleeding Disorders of Unknown Cause | journal=Hämostaseologie | date=2024-07-01 | issn=0720-9355 | doi=10.1055/a-2330-9112 | language=de | page=| pmid=38950624 }}</ref>

[[Aspirin]] and other [[cyclooxygenase]] inhibitors can significantly prolong bleeding time. While [[warfarin]] and [[heparin]] have their major effects on coagulation factors, an increased bleeding time is sometimes seen with use of these medications as well.

People with [[von Willebrand disease]] usually experience increased bleeding time, as [[von Willebrand factor]] is a platelet adhesion protein, but this is not considered an effective diagnostic test for this condition.<ref name="y378"/>

It is also prolonged in [[hypofibrinogenemia]].<ref name="urlBleeding Time">{{cite web|url=http://www.obgyn.ufl.edu/obgyn101/Lab/Bleeding%20Time.htm |title=Bleeding Time |access-date=2009-01-02 |url-status=dead |archive-url=https://web.archive.org/web/20060914061228/http://www.obgyn.ufl.edu/obgyn101/Lab/Bleeding%20Time.htm |archive-date=September 14, 2006 }}</ref>
