Bleeding time

How the test is performed:

A blood pressure cuff is placed on the upper arm and inflated. Two incisions are made on the lower arm. These are about 10 mm (less than 1/2 inch) long and 1 mm deep (just deep enough to cause minimal bleeding). The blood pressure cuff is immediately deflated. Blotting paper is touched to the cuts every 30 seconds until the bleeding stops. The length of time it takes for the cuts to stop bleeding is recorded.
