The examination report of the four items of coagulation mainly interprets the prothrombin time, prothrombin time, fibrinogen, and activated partial thromboplastin time.
1. Prothrombin time: it is the time needed to add excessive tissue thrombin and calcium ions into the patient’s plasma, and the prothrombin is converted into thrombin to make the blood coagulate, and it takes 11-13 seconds to be normal, and it is abnormal if it is greater than or less than normal.
2. Prothrombin time: the time needed for plasma clotting after adding “standardized” prothrombin solution into the patient’s plasma is prothrombin time, the normal value is 16-18 seconds, higher or lower than the normal value is abnormal.
3. Fibrinogen: also known as coagulation factor II, is a glycoprotein synthesized by the liver, which can promote platelet aggregation and play an important role in human coagulation function. The normal range is 2-4g/L. Elevated fibrinogen is common in myocardial infarction, thrombosis, atherosclerosis and other diseases, and decreased fibrinogen is common in bleeding.
4. Activated partial thromboplastin time: is simulated in vitro endogenous coagulation of all the conditions, the determination of the lack of platelets plasma clotting time required, the normal value of men and women there are differences between men and women, men are 37 ± 3.3 seconds. The normal value varies between men and women and is 37.5±3.3 seconds for men and 37.5±2.8 seconds for women, with higher or lower than normal values being considered abnormal.
If the test report of the four items of coagulation is abnormal, it is recommended to go to a professional hospital to clarify the cause of the disease and under the guidance of the doctor for further examination and treatment.
