What material is used to wick away each blood drop during Buccal Mucosal Bleeding Time?

Explanation:
In Buccal Mucosal Bleeding Time, you need a consistent way to blot away blood without disturbing the clot. Filter paper is used because it is absorbent, sterile, and inert, and it minimizes fiber shedding or added irritation. This standardizes the blotting process so the time to hemostasis reflects true clotting ability. Cotton swabs can leave fibers and vary in absorption, tissue is inconsistent, and paper towels are rough and unreliable; they can introduce variability or irritation. So, the material used to wick away each blood drop is filter paper.
