Autoprothrombin

Autoprothrombin is a term used in medicine to refer to prothrombin, which is synthesized in the human body. Prothrombin is a protein that is involved in the blood clotting process and plays an important role in protecting the body from bleeding.

Autoprothrombin is formed in the liver and is one of the components of the blood coagulation system. It can also be found in other body tissues and fluids, such as saliva, urine, and cerebrospinal fluid.

The normal level of autoprothrombin in the blood is about 70-130% of normal. However, in some diseases, such as hemophilia and other blood clotting disorders, the level of autoprothrombin can be significantly reduced.

If autoprothrombin levels fall below normal, it can lead to bleeding and other health problems. For example, in hemophilia, the level of autoprothrombin falls below 50%, which can lead to serious bleeding.

Special blood tests are used to diagnose autoprothrombin levels. If the level of autoprothrombin is below normal, this may indicate the presence of diseases associated with blood clotting disorders.

In general, autoprothrombin is an important component of the blood coagulation system and can be used in the diagnosis and treatment of various diseases.
