A bleeding time test measures how long it takes blood to clot. This test is not used very often.
this test, a health professional puts a blood pressure cuff on your upper arm
and inflates it slightly. The cuff remains inflated throughout the test. Then
your forearm is cleaned and one or two small incisions [about
1 mm (0.04 in.) deep] are made. Every 30
seconds, blood is gently blotted away until the bleeding stops.
The health professional will time how long it takes for the bleeding
to stop in each incision (cut). This measurement is the bleeding time. If two
cuts are made, your bleeding time is the average time for both areas to stop bleeding.
The test generally takes less than 10 minutes. If bleeding lasts longer than
10 minutes, the test is usually stopped.
If the cuts take too long to clot, you may have a bleeding
