For the Simplate Bleeding Time Test, where should the puncture site be located relative to the antecubital bend?

• A. 5 cm below the antecubital bend
• B. 2 cm above the antecubital crease
• C. 1 cm below the elbow crease
• D. 10 cm lateral to the antecubital bend

Answer: (A)

Bleeding time with the Simplate is designed to be reproducible, so the puncture is placed at a fixed spot on the forearm rather than at random. The standard location is about 5 cm below the antecubital bend on the volar forearm. This distance keeps the incision away from the elbow crease and joint movement, provides a consistent skin thickness and vascular environment, and matches the device’s guidelines. Placing the wound here makes the time to hemostasis comparable between patients and tests, so the result reflects platelet function and clotting ability rather than anatomical variation.
