Serum glucagon (PG)

Glucagon is synthesized and secreted by islet α cells, which raises blood glucose concentration and antagonizes insulin action. This test can reflect the function of islet alpha cells. Increased: seen in insulin-insensitive diabetes, glucagonoma (islet alpha cell tumor), acute pancreatitis, hypothyroidism, acromegaly, Cushing's syndrome, cirrhosis, acute myocardial infarction with cardiac Sexual shock. And after treatment with steroids. Reduction: seen in congenital α cell deficiency, chronic pancreatitis, hypopituitarism, Addison's disease, and reduction of glucagon secretion. Basic Information Specialist classification: Digestive examination classification: blood examination Applicable gender: whether men and women apply fasting: fasting Analysis results: Below normal: Found in congenital α cell deficiency, chronic pancreatitis, hypopituitarism, Addison's disease, and reduction of glucagon secretion. Normal value: Serum PG: 50-150ng/L Above normal: Found in insulin-insensitive diabetes, glucagonoma (islet alpha cell tumor), acute pancreatitis, hypothyroidism, acromegaly, Cushing's syndrome, cirrhosis, acute myocardial infarction with cardiogenic shock . And after treatment with steroids. 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. After 8 pm on the day before the medical examination, fasting should be done to avoid affecting the detection of indicators such as blood glucose in the second sky. Normal value 50 ~ 150ng / L. Clinical significance Increased in insulin-insensitive diabetes, glucagonoma (islet alpha cell tumor), acute pancreatitis, hypothyroidism, acromegaly, Cushing's syndrome, cirrhosis, acute myocardial infarction with cardiogenicity shock. And after treatment with steroids. Reduced in congenital α cell deficiency, chronic pancreatitis, hypopituitarism, Addison's disease, glucagon secretion reduction. High results may be diseases: neonatal asphyxia, glucagonoma syndrome, chronic pancreatitis considerations 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. 4, when the tension, strenuous exercise, can increase plasma glucagon. 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 RIA method. 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.
