Anti-platelet membrane glycoprotein autoantibodies

The anti-platelet membrane glycoprotein autoantibody assay is a test for anti-platelet membrane glycoprotein antibodies in the blood, which helps to provide a basis for later blood testing. Positive, there are many kinds of PMGAA, such as GMPIIb, GMPIII1a, GMP1b and so on. Positive in chronic idiopathic thrombocytopenic purpura. Some SLE and rheumatoid arthritis can also be positive, but the titer is low. There are two main types of PAA, namely IgG type and IgM type. The IgG type of acute IPT patients is significantly higher than that of chronic ITP patients. Dynamic observation of IgG type PAA changes can help identify acute and chronic ITP. IgG within 2 weeks after corticosteroid treatment Type PAA turned negative, more suggestive of chronic type, and better prognosis. 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 in chronic idiopathic thrombocytopenic purpura. Tips: When you take blood, you should relax your mind, avoid the contraction of blood vessels caused by fear, and increase the difficulty of blood collection. Normal value The result of the test was negative. Clinical significance Abnormal result Positive, there are many kinds of PMGAA, such as GMPIIb, GMPIII1a, GMP1b and so on. Positive in chronic idiopathic thrombocytopenic purpura. Some SLE and rheumatoid arthritis can also be positive, but the titer is low. There are two main types of PAA, namely IgG type and IgM type. The IgG type of acute IPT patients is significantly higher than that of chronic ITP patients. Dynamic observation of IgG type PAA changes can help identify acute and chronic ITP. IgG within 2 weeks after corticosteroid treatment Type PAA turned negative, more suggestive of chronic type, and better prognosis. People who need to be examined are suspected of having platelet diseases. Positive results may be diseases: thrombocytopenic purpura, rheumatoid arthritis precautions Inappropriate crowd: no 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 Generally no taboos. Adverse reactions and risks Can be infected concurrently.
