Reasons for the increase and decrease in bleeding time

The reference values of bleeding duration for Duke are 2-3 minutes. Bleeding time characterizes the elasticity of blood vessels and their ability to reduce with trauma, as well as the state of the platelet system (ability to adhesion and aggregation). The lengthening of bleeding time is of practical importance. It reflects a violation of primary hemostasis due to thrombocytopenia, thrombocytopathy, disruption of the vascular wall, or a combination of these factors.
Diseases and conditions in which the bleeding time can vary
| Increase the coagulation time | Shortening the coagulation time |
|
Thrombocytopenic purpura Atrombopenic purpura Scorbut Phosphorus poisoning Hemorrhagic diathesis Leukemia Splenomegaly cirrhosis of the liver Long-term use of certain drugs (acetylsalicylic acid) Hemorrhages with hypofibrinogenemia Vascular malformations with underdevelopment of pre-capillary contraction (microangiopathy) DIC-Syndrome | More often the consequence of a technical error in the test or testifies to the increased spastic ability of capillaries |
