Bleeding time is a blood test that looks at how fast small blood vessels close to stop you from bleeding.
How the test is performed:
A blood pressure cuff inflates around your upper arm. While on the cuff is on your arm, the health care provider makes two small cuts on the lower arm. They are just just deep enough to cause a tiny amount of bleeding.
The blood pressure cuff is immediately deflated. Blotting paper is touched to the cuts every 30 seconds until the bleeding stops. The health care provider records the time it takes for the cuts to stop bleeding.
How to prepare for the test:
Certain medications may change the test results. Always tell your doctor what medications you are taking, even over-the-counter drugs. Drugs that may increase bleeding times include dextran, indomethacin, and salicylates (including aspirin).
Your doctor may tell you to stop taking certain medicines a few days before the test. Never stop taking medicine without first talking to your doctor.
How the test will feel:
The tiny cuts are very shallow. Most people say it feels like a skin scratch.
