Anti-thyroid microsomal antibody (ATMA)

Anti-thyroid microsomal antibodies (ATMA) have the same clinical significance as anti-thyroglobulin antibodies, both of which detect their own antibodies. Basic Information Specialist classification: growth and development check classification: immunological examination Applicable gender: whether men and women apply fasting: not fasting Analysis results: Below normal: Normal value: no Above normal: negative: normal. Positive: Positive in Hashimoto thyroiditis, hyperthyroidism, primary hypothyroidism. Tips: After 8 pm on the day before the medical examination, you should start fasting for 12 hours. Normal value The test result <1:10 is negative (immunofluorescence). Clinical significance Positive in Hashimoto thyroiditis, hyperthyroidism, primary hypothyroidism. It has the meaning of auxiliary diagnosis and efficacy judgment, if any anti-thyroglobulin antibody is negative, and anti-thyroid microsomal antibody is positive. If both antibodies are measured simultaneously, the positive detection rate of anti-thyroid autoantibodies can be increased. 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 medical examination, you should start fasting for 12 hours to avoid affecting the test results. 3, should relax when taking blood, to avoid the contraction of blood vessels caused by fear, increase the difficulty of blood collection. Second, after blood draw should pay attention to: 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. 3. Please inform the doctor about the recent medication and special physiological changes before the test. Inspection process Same as ELISA. Not suitable for the crowd There are no taboos. Adverse reactions and risks There are no related complications and hazards.
