Anti-platelet membrane glycoprotein autoantibody assay

The anti-platelet membrane glycoprotein autoantibody assay is a method for the determination of blood anti-platelet membrane glycoprotein autoantibodies by flow cytometry (FCM) and its significance for the diagnosis of idiopathic thrombocytopenic purpura (ITP). Idiopathic thrombocytopenic purpura (ITP) is an immune disease in which anti-platelet autoantibodies are combined with platelet antigens in patients, causing platelets to rapidly clear from the circulation. Basic Information Specialist classification: cardiovascular examination classification: blood examination Applicable gender: whether men and women apply fasting: fasting Analysis results: Below normal: Normal value: no Above normal: negative: normal. Positive: Positive for idiopathic thrombocytopenic purpura (ITP). Tips: Do not eat too greasy, high-protein foods the day before, and avoid heavy drinking. Normal value The result of the test was negative. Clinical significance Abnormal results were positive, ie, FCM test, fluorescence showed positive, indicating idiopathic thrombocytopenic purpura (ITP). The population to be examined has a population with acute clinical hemorrhage and a history of blood. Positive results may be diseases: idiopathic thrombocytopenic purpura 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: venous blood is required. 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 Dizziness or fainting: When blood is drawn, due to emotional overstress, fear, reflex caused by vagus nerve excitability, blood pressure drop, etc., the blood supply to the brain is insufficient to cause fainting or dizziness.
