Heparin-antithrombin IV complex

This test is used as an important means to monitor the monitoring of heparin in clinical use and prevent bleeding. Heparin quantification is commonly used for the monitoring of heparin anticoagulant therapy. In the liver and pancreatic diseases, heparin in the blood can be increased. Heparin levels increase infectious diseases, disseminated intravascular coagulation (DIC), anaphylactic shock, cirrhosis, coronary heart disease, uremia. Basic Information Specialist classification: cardiovascular examination classification: blood examination Applicable gender: whether men and women apply fasting: fasting Tips: An empty stomach is required for inspection. Normal value The chromogenic substrate method has a residual thrombin content of 93.08%±4.3% and a heparin ELISA method of 1.05 to 1.85 μg/L. Clinical significance Abnormal results: Heparin levels increase infectious diseases, disseminated intravascular coagulation (DIC), anaphylactic shock, cirrhosis, coronary heart disease, uremia. Need to check the crowd: patients need to be diagnosed with infectious diseases, disseminated intravascular coagulation (DIC) and other diseases. High results may be diseases: cirrhosis, anaphylactic shock precautions Preparation before inspection: fasting. Requirements for examination: According to the difference of blood collection sites, blood routine test specimens are obtained. The most commonly used methods are venous blood collection and peripheral capillary blood collection. Blood samples used for routine blood tests must be treated with anticoagulant anticoagulation, and anticoagulants with relatively small effects on leukocyte morphology and platelets using EDTA salts, etc. within 5 minutes or 30 minutes after specimen collection, within 8 hours ( Room temperature) detection. Inspection process In a quiet state, venous blood is drawn using a clean test tube on an empty stomach. The measurement was carried out using a chromogenic substrate chromogenic method. 1. Comparison of quantitative parallel lines and standard curves. Two spectrophotometric methods for the determination of anti-FXa or anti-FIIa titers by spectrophotometry of chromogenic substrates using chromogenic substrates for FXa or FIIa-specific 405 nm color reaction. difference. 2. The spectrophotometric method and the blood coagulation method (observing the coagulation time of rabbit whole blood or rabbit plasma) comparing the chromogenic substrate were used to determine the similarities and differences of the anti-thrombin (anti-FIIa) titer of LMWH. Not suitable for the crowd People with liver and pancreatic diseases. Adverse reactions and risks Risk of infection: If you use an unclean needle, you may be at risk of infection.
