Editing Bleeding time (section)

===Duke's method===

With the Duke's method, the patient is pricked with a special needle or lancet, preferably on the [[earlobe]]<ref name="isbn0-7817-3066-X">{{cite book |author1=Schafer, Andrew I. |author2=Loscalzo, Joseph |title=Thrombosis and hemorrhage |publisher=Lippincott Williams & Wilkins |location=Hagerstwon, MD |year=2003 |pages=397  |isbn=978-0-7817-3066-2 }}</ref> or [[fingertip]], after having been swabbed with alcohol. The prick is about 3–4&nbsp;mm deep. The patient then wipes the blood every 30 seconds with a filter paper. The test ceases when bleeding ceases. The usual time is about 2–5 minutes.

This method is not recommended and cannot be standardized because it can cause a large local hematoma.<ref name=":0" />
