Bleeding time is a medical term referring to a basic diagnostic test performed to assess the function of an individual's platelets.

Pronunciation

Bleeding time is pronounced as /ˈbliːdɪŋ taɪm/.

Etymology

The term "bleeding time" is derived from the English words "bleed," which means to lose blood from the body, and "time," which refers to the measured or measurable period during which an action, process, or condition exists or continues.

Definition

Bleeding time is a medical test that measures how quickly small blood vessels in the skin stop bleeding. This is an indication of how well platelets, small cell fragments in the blood, are functioning. Platelets are a crucial part of the clotting process, and an extended bleeding time can indicate a platelet function disorder.

Procedure

The test is performed by making a small incision on the lower arm, and the time it takes for bleeding to stop is measured. The normal range for bleeding time is usually between 2 and 9 minutes.
