Which is the correct sequence for performing Buccal Mucosal Bleeding Time?

• A. Incise first, fold lip, start timer, blot every 1 second, stop when no bleeding
• B. Make incision, fold lip, start timer, blot at 10 seconds, stop timer, wick with tissue
• C. Fold lip, blot with paper, incise and start timer, stop timer when blood stops, read from stopwatch
• D. Fold lip, incise and start timer when blood appears, blot at 5-second intervals, stop timer when bleeding stops, wick away each drop with paper

Answer: (D)

The test relies on a consistent, stepwise sequence to measure how long it takes for bleeding to stop after a small mucosal incision, reflecting primary hemostasis and platelet function. You expose the buccal mucosa by folding the lip, then make a standardized superficial incision. The timing starts when bleeding from that incision appears, so the recorded interval captures the duration of active bleeding until hemostasis occurs. You blot the site with absorbent paper at fixed short intervals (commonly every 5 seconds) to keep the area clear and to detect the exact moment the bleeding ceases. You continue this until no bleeding is present, then stop the timer. Wicking away each drop with paper helps prevent blood pooling from altering the readout and ensures a precise endpoint. This sequence is preferred because starting the timer only after bleeding begins, and blotting at uniform short intervals, provides a reproducible and objective measurement. Other sequences can mis-timing when the clock starts or how often you remove blood, leading to inconsistent results.
