Plasma coagulation factor IX activity assay

The blood coagulation factor IX activity is measured by measuring the activity of plasma coagulation factor IX, that is, anti-hemophilia globulin B (AHGB), and can diagnose hereditary type B hemophilia. The test results were positive, indicating a loss of plasma coagulation factor IX, possibly with hereditary type B hemophilia. This type of hemophilia is relatively rare compared to type A, affecting approximately one in 35,000 people, and the majority of the patients are male. Basic Information Specialist classification: growth and development examination classification: blood examination Applicable gender: whether men and women apply fasting: not fasting Tips: Do not eat too greasy, high-protein foods the day before, and avoid heavy drinking. The alcohol content in the blood directly affects the test results. Normal value The test result was negative. Clinical significance Abnormal result The test results were positive, indicating a loss of plasma coagulation factor IX, possibly with hereditary type B hemophilia. This type of hemophilia is relatively rare compared to type A, affecting approximately one in 35,000 people, and the majority of the patients are male. People who need to be examined have people with hemophilia. Positive results may be diseases: hemophilia precautions Taboo before the test: Do not eat too greasy, high-protein foods the day before the test, to avoid heavy drinking. The alcohol content in the blood directly affects the test results. After 8 pm on the day before the medical examination, you should fast. Requirements for examination: When taking blood, you should relax your mind to avoid the contraction of blood vessels caused by fear and increase the difficulty of blood collection. Inspection process Vascular blood collection was used for testing. Before venous blood collection, carefully check that the needle is securely installed and that there is air and moisture in the syringe. The needle used should be sharp, smooth, ventilated, and the syringe should not leak. Firstly, the skin was disinfected from the inside to the outside and clockwise from the selected venipuncture with a 30g/L iodine swab. After the iodine was volatilized, the iodized trace was wiped out in the same way with a 75% ethanol swab. Fix the lower end of the venipuncture site with the thumb of the left hand, hold the syringe syringe with the thumb and middle finger of the right hand, and fix the needle lower seat with the index finger, so that the bevel of the needle and the scale of the syringe are upward, and the needle is inclined along the vein to make the needle and the skin obliquely penetrate the skin at an angle of 30°. Then, through the vein wall, enter the venous cavity forward at an angle of 5°. After seeing the blood return, the needle will be probed into the spot to avoid the needle slipping out when the blood is collected; but it is not possible to use a deep puncture to avoid hematoma, and immediately remove the cuff. Needle plug can only be pumped out, can not be pushed in, so as to avoid injecting air into the vein to form a gas plug, causing serious consequences. Remove the syringe needle and slowly inject the blood into the anticoagulation tube along the tube wall to prevent hemolysis and foam. Not suitable for the crowd A patient with hemophilia and severe clotting factor deficiency. Adverse reactions and risks Risk of infection: If you use an unclean needle, you may be at risk of infection.
