What is the BT(Bleeding Time) test?
A bleeding time is a crude test of haemostasis. It also indicates how well platelets interact with blood vessel walls to form a clot. Bleeding time is used most often to detect qualitative defects in platelets. The bleeding time test is usually used for patients who have a history of prolonged bleeding after cuts or who have a family history of bleeding disorders.
What are the other names for the BT(Bleeding Time) test?
The other names are BT test.
What are the test parameters included in the BT(Bleeding Time) test?
There is only one parameter.
What does a BT(Bleeding Time) test measure?
A bleeding time was the first in vivo platelet function test. It analyses the time taken for bleeding to stop after a standardised incision is made into the skin, usually on the anterior forearm.
What’s the normal range of BT(Bleeding Time)?
2 - 7 minutes.
Who should get a BT(Bleeding Time) test?
The bleeding time test can be prescribed by the healthcare provider if the patient is someone who is experiencing an issue with blood clotting wherein the blood is not able to stop flowing after an injury such as a cut or a puncture.. In case of any surgery or procedure being done, bleeding time is taken.
Blood clotting disorder symptoms are: delay in blood clotting and longer bleeding time. The bleeding time test is the most common test to check if the blood clotting system has issues.
There are few other tests available to evaluate if a person is suffering from bleeding problems. If there is prolonged bleeding in a person, it indicates that the person has an acquired defect in platelet function. The test is also carried out to determine epistaxis.
Are there any preparations needed for the BT(Bleeding Time) test?
No special preparation is required. Fasting is not required.
What is the cost of the BT(Bleeding Time) test?
What is the type of sample required?
This test requires a blood sample.
Who processes the BT(Bleeding Time) test?
A healthcare provider, who is also called a phlebotomist, usually performs blood draws, including those for bleeding time tests, but any healthcare provider trained in drawing blood can perform this task. These samples are sent to a lab where a medical laboratory scientist prepares the samples and performs the tests on analysers or manually.
What should I expect during my BT(Bleeding Time) test?
You might expect to experience the following during the blood test or a blood draw:
You sit comfortably on the chair.
They will disinfect the puncture site with an alcohol swab to minimize the risk of infection.
They will place a pressure cuff around your arm and inflate it.
Next, they make two pricks on your lower arm. These will be deep enough to cause slight bleeding. You may feel a slight scratch when they make the cuts, but the cuts are very shallow and shouldn’t cause much pain.
They remove the cuff from your arm.
By using a stopwatch or a timer, they blot the pricked site with paper every 30 seconds until the bleeding stops. They record the time it takes for you to stop bleeding and then apply the band-aid to the pricked site.
Usually, if the pricked site continues to bleed after 20 minutes, the healthcare provider notes that the bleeding time is over 20 minutes.
What should I expect after my BT(Bleeding Time) test?
Once a phlebotomist will note down the bleeding times and the same will be sent to the laboratory and reports will be shared with you.
What are the risks of a BT(Bleeding Time) test?
Blood tests are common. Your skin is being pricked. There may be a risk of excessive bleeding and infection. Some bleeding is a certainty since the purpose of the test is to make you bleed.
However, because the test pricks are relatively shallow, the risk of excessive bleeding is minimal and complications are extremely rare.

What do the results of a BT(Bleeding Time) test mean?
Normal bleeding time is usually between 2 - 8 minutes. It may be determined if the person has haemophilia or von Willibrand’s disease. If the bleeding time is outside the normal range, it could imply an underlying platelet defect, and there should be more tests done to confirm it. An abnormal bleeding time indicates that the person could have acquired a platelet function defect. An acquired platelet function defect develops after birth.
In this kind of defect, the platelets might not be working properly, or the body may be producing too many platelets or fewer platelets. Usually, abnormal results could mean:
That person has a defect in the blood vessels wherein the blood vessels are unable to transport blood properly throughout the body.
A person has a genetic platelet function disorder by birth. This genetic disorder could affect the function of the platelets.
A person could be suffering from thrombocythemia, wherein the person's bone marrow starts producing too many platelets in the body.
A person could be suffering from thrombocytopenia, where the person's bones start producing a small number of platelets in the body.
A person might be suffering from Von Willebrand's disease. It is a hereditary disease that affects the process of blood coagulation in a person.
What are normal BT(Bleeding Time) test results?
2 - 7 minutes.
The normal ranges can vary slightly among different laboratories. Some of the labs use different measurements or might do tests on the different samples. Speak to your healthcare provider about the meaning of your specific test results.
What other tests might I have along with this test?
Prothrombin Time, Platelet Counts, Von Willebrand
