Serum mercury (Hg)

The human body contains 12 to 18 mg of manganese. Manganese is mainly absorbed in the intestines, and the absorption rate is also low due to the low solubility of manganese in food. Basic Information Specialist classification: growth and development check classification: biochemical 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. Normal value <1.57 μmol/L (0 to 0.0315 mg/dl). Clinical significance Increased: seen in acute mercury poisoning, blood mercury and urinary mercury increased. High results may be diseases: multifocal motor neuropathy 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. 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. Third, found that serum mercury is elevated, should seek medical advice in a timely manner. Inspection process Take the right amount of blood and send it for inspection. Not suitable for the crowd A patient with hemophilia and severe clotting factor deficiency. Adverse reactions and risks Risk of infection: If you use an unclean needle, you may be at risk of infection.
