The time required for the bleeding from a small puncture wound of the finger to stop under carefully controlled conditions.
A test of the clotting ability of someone’s blood, by timing the length of time it takes for the blood to congeal.
The time required for blood to stop flowing from a small wound or pinprick. It is assessed using one of several techniques. Depending on the method used, the time may vary from 1 to 3 min (Duke method) or from 1 to 9 min (Ivy method). The Duke method consists of timing the cessation of bleeding after the ear lobe has received a standardized puncture. The Ivy method is done in a similar manner following puncture of the skin of the forearm. The validity of this test to predict clinically significant bleeding has been questioned.
An evaluation of platelet function, which involves measuring the rate at which they form plugs to control bleeding from injured blood vessels, is conducted. This assessment is performed by making two small incisions in the forearm and recording the time it takes for the bleeding from these cuts to cease.
The duration it normally takes for bleeding from a needle prick to cease is around four to five minutes.
The duration for a small puncture, often on the earlobe, to cease bleeding typically ranges from one to three minutes in healthy individuals. However, for those with hemophilia, this bleeding can persist for an undetermined period.
