Bleeding time test is one of the steps of the coagulation test, which is performed by 2 methods, which are Duke and IVY methods.
Besides the clinical diagnostic information, the bleeding time test plays a very important role in detecting abnormal coagulation problems. From there, helping doctors make faster and more accurate diagnoses.

In the body, when the blood leaves the vessel, it will be coagulated by the exogenous route. Initial coagulation testing includes:
Platelet count test : Normally the platelet count in circulating blood is 140-400 G/L. Bleeding time test: There are 2 types of bleeding time test, that is Duke or Ivy test. According to the Duke method, normal bleeding time is less than 5 minutes; With the Ivy method, the normal bleeding time is less than 3 minutes. Coagulation test: This is a test technique performed to monitor the phenomenon of blood clots in a test tube placed at a 37°C water thermostat. The ligature test: This method will use a sphygmomanometer to maintain a pressure of 90-100 mmHg in the arm for 5 minutes, then count the bleeding spots below the garo. The method test is positive in cases of low platelet count or abnormalities in platelet function and vascular structure. Platelet aggregation test to evaluate platelet function.

Bleeding time testing should be performed by a highly trained hematologist. The necessary tools are a blood needle, a timer, alcohol sanitizer and cotton swabs. The coagulation test procedure is performed as follows:
First step, medical staff will disinfect the skin of the earlobe with alcohol, then use a needle to prick the disinfected area to create a high-grade wound. about 2mm deep and use a watch to monitor the bleeding time. During this time, medical staff will use paper to gently blot but not stop the bleeding. Apply once every 30 seconds, until the bleeding stops.
