reptilase time

The reptilian enzyme has a thrombin-like effect and is capable of coagulating the fibrin protein but is insensitive to factors that inhibit thrombin. Basic Information Specialist classification: cardiovascular examination classification: blood examination Applicable gender: whether men and women apply fasting: fasting Tips: If there is local congestion, use a warm towel after 24 hours to promote absorption. Normal value Normally it is 18 to 22 s, and it is abnormal for more than 3 s over the control. Clinical significance Abnormal result (1) When heparin is present in the blood circulation, the thrombin time is prolonged, and the reptilase time is normal. (2) The reptilase time was significantly prolonged and the thrombin time was prolonged, which was found in fibrinogen-free. (3) Reptile enzyme and thrombin time are prolonged, which is seen in fibrinogen reduction, abnormal fibrinogenemia, and fibrinogen (original) degradation products (FDP). People who need to be examined have gastrointestinal bleeding and mucosal bleeding, such as those with excessive menstrual blood. High results may be diseases: hemophilia 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 Have a coagulopathy such as hemophilia. Adverse reactions and risks Bleeding: After blood collection, use sterile cotton lump or other disinfecting hemostatic articles to tighten the needle to stop bleeding, especially for patients with coagulopathy should be given sufficient time to avoid bleeding.
