Calcitonin

Calcitonin is a peptide hormone synthesized and secreted by thyroxine follicular cells, which can reduce the concentration of calcium and phosphorus in plasma and inhibit the absorption of calcium and phosphorus. Basic Information Specialist classification: examination classification: endocrine examination Applicable gender: whether men and women apply fasting: fasting Analysis results: Below normal: Can be seen in thyroid congenital hypoplasia or surgical resection. Normal value: Serum ct (male): 0-14 ng / L Serum ct (female): 0-28ng/L Above normal: Can be seen in malignant tumors and acute and chronic renal insufficiency. negative: Positive: 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 Male is less than or equal to 14ng/L; Women are less than 28ng/L. Clinical significance Abnormal results: high serum calcium, malformation osteitis, hypercalcemia, menopausal osteoporosis, osteogenic defects. For the observation of curative effect and prognosis of malignant tumors, such as thyroid cancer or lung cancer surgery, serum ct continues to rise, indicating the formation of residual tumor tissue, poor prognosis. Increased serum ct can be seen in malignant tumors and acute and chronic renal insufficiency. The reduction of ct can be seen in thyroid congenital hypoplasia or surgical resection. People who need to be tested: bone headache, osteoporosis, elderly, thyroid cancer or lung cancer after surgery. High results may be diseases: thyroid microcarcinoma, thyroid cancer in children Before inspection: 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. Fasting for 12 hours before taking blood, taking fresh blood for inspection. When checking: 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. After inspection: 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 Blood tests, immunological or chemiluminescence. Not suitable for the crowd People with reduced hematopoietic function such as leukemia, various anemia, myelodysplastic syndrome, or people with thrombocytopenia should pay attention to blood draw, and should not take more or more blood. Adverse reactions and risks 1. After the blood is drawn, do not press the needle hole to avoid subcutaneous hematoma. If there is a small piece of bruise in the blood, it is slightly tender, please don't panic, you can do hot compress after 24 hours to promote the absorption of blood. The general small amount of congestion will gradually absorb in 3 to 5 days and the color will become lighter and return to normal. 2. After the blood draw, symptoms such as dizziness, vertigo, fatigue, etc. should be immediately supine, drink a small amount of syrup, and then undergo a physical examination after the symptoms are relieved.
