Serum Cadmium (Cd)

The normal adult cadmium load is 30 ~ 45mg, which accumulates from birth, so that the cadmium concentration in the body increases with age, until the age of 50. The source of cadmium is food, water and air. Therefore, the pollution of soil and water by cadmium-containing waste residue can cause harm to human health. After the cadmium absorbed by the oral cavity or respiratory tract is transferred to the blood, most of it is concentrated in the kidney and liver, and a small part is distributed in the pancreas, thyroid, gallbladder, testis and bone. Cadmium is mainly excreted in the urine. A significant decrease in the zinc/cadmium ratio in the human kidney (ie, ≤ 1.5) is a cause of hypertension. Acute cadmium poisoning has acute gastroenteritis or acute chemical pneumonia, pulmonary edema. Chronic cadmium poisoning has renal damage, proteinuria, emphysema, and pulmonary fibrosis. Basic Information Specialist classification: growth and development check classification: biochemical examination Applicable gender: whether men and women apply fasting: fasting Analysis results: Below normal: Rare. Normal value: Serum cadmium (Cd): 8.9-44.5μmol/L Above normal: Increased in high blood pressure, bronchitis, emphysema, lung cancer, renal failure and acute cadmium poisoning. 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 Serum cadmium (Cd) normal value: 8.9 ~ 44.5 μmol / L (0.1 ~ 0.5 μg / dl); poisoning amount: 0.89 ~ 26.7 μmol / L (10 ~ 300μg / dl). Clinical significance Increased in high blood pressure, bronchitis, emphysema, lung cancer, renal failure and acute cadmium poisoning. High results may be diseases: cadmium poisoning, renal failure, emphysema, pulmonary fibrosis 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. Inspection process Take 2ml of venous whole blood and immediately send it for examination. Detection method Atomic absorption spectrophotometry. Not suitable for the crowd no. Adverse reactions and risks no.
