What is the bleeding time test?
Bleeding time is a medical test that measures how fast small blood vessels in the skin stop bleeding. The bleeding time test is used to evaluate how well a person’s blood is clotting. The test evaluates how long it takes the vessels cut to constrict and how long it takes for platelets in the blood to seal off the hole.

How is clotting time test done?
Take the blood sample, mostly taken from the antecubital vein. 2 to 2.5 mL of the blood is taken, and 1 mL of the blood is in each test tubes. Start two stopwatches as you see the blood in the syringe. Keep the blood in the water bath and check for clotting by tilting each tube at intervals of 30 to 60 seconds.

Total accuracy of the test was 72.6% (95% CI: 65.7–78.5). Individuals with a prolonged LWCT had 2.4 times higher odds of presenting hypofibrinogenemia (DOR 2.4 [95% CI: 1.1–5.6]).
What is clotting time and bleeding time?
The normal bleeding time is between 2-7 minutes. The normal clotting time in a person is between 8-15 minutes. By understanding the time taken for blood to clot, it can be determined if the person has haemophilia or von Willibrand’s disease.
