What device is used to time the Buccal Mucosal Bleeding Time?

• A. Stopwatch or timer
• B. Stopwatch
• C. Timer
• D. Clock

Answer: (A)

Measuring Buccal Mucosal Bleeding Time requires tracking how long the bleeding lasts from the moment of the standardized mucosal incision until it stops. That calls for a device that gives an accurate elapsed-time readout. A stopwatch or timer does this by starting at zero and stopping when bleeding ceases, providing the exact duration in seconds or minutes. A regular clock shows the current time, not the duration, and while a countdown timer can indicate time remaining, you need to record the actual interval observed, which is precisely what a stopwatch or timer provides. In practice, clinicians typically use a stopwatch to time the bleeding because it directly measures the elapsed interval.
