Bleeding time
Bleeding time
GENERAL INFORMATION:
What is this test?
This test measures the time it takes for bleeding to stop when skin is cut. It is used to evaluate the ability of blood to form blood clots to stop bleeding.
Why do I need this test?
Laboratory tests may be done for many reasons. Tests are performed for routine health screenings or if a disease or toxicity is suspected. Lab tests may be used to determine if a medical condition is improving or worsening. Lab tests may also be used to measure the success or failure of a medication or treatment plan. Lab tests may be ordered for professional or legal reasons. You may need this test if you have:
- Pre-eclampsia
- von Willebrand disorder
How should I get ready for the test?
Before the test is performed, tell the health care worker if you are allergic to latex, use anticoagulants or other blood-thinning medications, or have a medical condition that decreases blood circulation or causes excess bleeding. Also tell the health care worker if you have been nauseated, light-headed, or have fainted during blood tests in the past.
How is the test done?
There are several ways that this test may be done. The healthcare worker will either make a small incision or lance your forearm or earlobe. Then the healthcare worker will swab blood from the area until it stops bleeding. A timer is used to measure the length of time it takes your blood to clot.
How will the test feel?
The amount of discomfort you feel will depend on many factors, including your sensitivity to pain. Communicate how you are feeling with the person doing the test. Inform the person doing the test if you feel that you cannot continue with the test.
What should I do after the test?
A bandage, cotton ball, or gauze may be placed on the area where the test was performed. You may be asked to apply pressure to the area. Avoid strenuous exercise immediately after your lab test. Contact your healthcare worker if you feel pain, see redness or swelling, or there is discharge from the test site.
CARE AGREEMENT:
You have the right to help plan your care. To help with this plan, you must learn about your health condition and how it may be treated. You can then discuss treatment options with your caregivers. Work with them to decide what care may be used to treat you. You always have the right to refuse treatment.
