Platelet-associated immunoglobulin (PAIgG, PAIgA, PAIgM)

Platelet-associated immunoglobulin, also known as platelet-associated antibody, is a self-anti-platelet antibody in patients, including PAIgG, PAIgA, and PAIgM. Elevated PAIgG has a definitive significance for primary thrombocytopenic purpura. Other thrombocytopenic purpura is often high in all three indicators. Increased PAIgG is seen in idiopathic thrombocytopenic purpura, certain immune diseases such as systemic lupus erythematosus, chronic active hepatitis, multiple myeloma, and diseases caused by immune complexes. The decrease in PAIgG was seen in patients with thrombocytopenic purpura treated with hormones, and the prognosis of PAIgG decreased within two weeks. Basic Information Specialist classification: cardiovascular examination classification: immune examination Applicable gender: whether men and women apply fasting: fasting Tips: Do not eat too greasy, high-protein foods the day before the blood draw, avoid heavy drinking. The alcohol content in the blood directly affects the test results. Normal value PAIgG 0 ~ 78.8 ng / 107 platelets. PAIgM0 ~ 7.0ng / l07 platelets. PAIgA0 ~ 2.0ng / 107 platelets. Clinical significance Elevated PAIgG has a definitive significance for primary thrombocytopenic purpura. Other thrombocytopenic purpura is often high in all three indicators. Increased PAIgG is seen in idiopathic thrombocytopenic purpura, certain immune diseases such as systemic lupus erythematosus, chronic active hepatitis, multiple myeloma, and diseases caused by immune complexes. The reduction of PAIgG is seen in patients with idiopathic thrombocytopenic purpura and is effective by hormone therapy. The prognosis of PAIgG decreased within two weeks. Precautions First, the precautions before blood draw 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 physical examination, fasting should be done to avoid affecting the detection of indicators such as blood glucose in the second sky. 3, should relax when taking blood, to avoid the contraction of blood vessels caused by fear, increase the difficulty of blood collection. Patients with a history of fainting should explain in advance and will make special arrangements. Second, should pay attention after blood draw 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 Subjects were venously collected and assayed in time for serum separation. Not suitable for the crowd 1. Patients who have taken contraceptives, thyroid hormones, steroid hormones, etc., may affect the results of the examination and prohibit patients who have recently taken the drug history. 2, special diseases: patients with hematopoietic function to reduce disease, such as leukemia, various anemia, myelodysplastic syndrome, etc., unless the examination is essential, try to draw less blood. Adverse reactions and risks 1, subcutaneous hemorrhage: due to pressing time less than 5 minutes or blood draw technology is not enough, etc. can cause subcutaneous bleeding. 2, discomfort: the puncture site may appear pain, swelling, tenderness, subcutaneous ecchymosis visible to the naked eye. 3, dizzy or fainting: in the blood draw, due to emotional overstress, fear, reflex caused by vagus nerve excitement, blood pressure decreased, etc. caused by insufficient blood supply to the brain caused by fainting or dizziness. 4. Risk of infection: If you use an unclean needle, you may be at risk of infection.
