Bleeding Time normal value is expressed in which unit?

Bleeding Time normal value is expressed in which unit?

• A. seconds
• B. hours
• C. minutes
• D. days

Answer: (C)

Bleeding time is a measurement of how long it takes for bleeding to stop after a standardized skin incision. Because this stoppage occurs over a short period, the normal value is expressed in minutes. Expressing it in seconds would divide a small range too finely, while hours or days would be far outside the actual time course of initial hemostasis. In practice, normal ranges are typically a few minutes, depending on the method used, reflecting the duration of the bleeding episode.
