thrombin time

Thrombin time is a convenient test for detecting the function of coagulation, anticoagulation, and fibrinolytic systems. In particular, it is known whether fibrin in plasma contains a sufficient amount of fibrinogen and whether the result is normal. The shortening of thrombin time is seen in abnormal fibrinemia, the presence of calcium ions in the blood, or the acidity of the blood. Basic Information Specialist classification: growth and development examination classification: blood examination Applicable gender: whether men and women apply fasting: fasting Tips: Do not eat too greasy, high-protein foods the day before the blood draw, avoid heavy drinking. Normal value 16 ~ 18s; more than 3s over normal control is abnormal. Clinical significance Abnormal results Thrombin time prolongation is seen in plasma fibrinogen reduction or structural abnormalities, clinical use of heparin, or heparin-like anticoagulant substances in liver disease, nephropathy and systemic lupus erythematosus, and fibrinolytic system hyperfunction. The shortening of thrombin time is seen in abnormal fibrinemia, the presence of calcium ions in the blood, or the acidity of the blood. High results may be diseases: hemophilia A, amniotic fluid embolism precautions Before inspection: 1, do not eat too greasy, high-protein food the day before the blood, to avoid heavy drinking. The alcohol content in the blood directly affects the test results. 2. After 8 pm on the day before the medical examination, you should start fasting for 12 hours to avoid affecting the test results. 3, should relax when taking blood, to avoid the contraction of blood vessels caused by fear, increase the difficulty of blood collection. After inspection: 1. After blood is drawn, local compression is required at the pinhole for 3-5 minutes to stop bleeding. Note: Do not rub, so as not to cause subcutaneous hematoma. 2, the pressing time should be sufficient. There is a difference in clotting time for each person, and some people need a little longer to clotting. Therefore, when the surface of the skin appears to be bleeding, the compression is stopped immediately, and the blood may be infiltrated into the skin due to incomplete hemostasis. Therefore, the compression time is longer to completely stop bleeding. If there is a tendency to bleed, the compression time should be extended. 3, after the blood draw symptoms of fainting such as: dizziness, vertigo, fatigue, etc. should immediately lie down, drink a small amount of syrup, and then undergo a physical examination after the symptoms are relieved. 4. If there is localized congestion, use a warm towel after 24 hours to promote absorption. Inspection process Inspection method: draw blood. Not suitable for the crowd Hemophilia and diffuse intravascular coagulation. Adverse reactions and risks Infection: Pay attention to aseptic operation when collecting blood, avoid contamination of water and other parts at the blood collection site to avoid local infection.
