Whole blood cadmium

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 Tips: Due to the different measurement methods and regions, the published reference values ​​are very different, so it is difficult to compare, even with the same method, the normal upper limit is also 3 times different. Normal value Whole blood is 0.32 to 2.72. Urine is 0.12 to 2.58. The unit is μg/L, and the conversion formula μg/L×8.896=nmol/L. Clinical significance The acceptable level is 15 μg/L in blood and 15 μg/L in urine. Cadmium rise is seen in factory workers producing cadmium-containing appliances (electroplating technology), rechargeable dry cells, balancers and PVC stabilizers. The result of industrial use of this element is the accumulation of cadmium in the sludge of the wastewater filtration system. Enter the human body through the use of crops and animal guts from these soils. The actual cadmium carrying capacity of the organism can be measured by measuring serum and urine. There is no good correlation between hair load and cadmium content in vital organs such as liver and kidney. In fact, the amount of hair analyzed is limited and does not reflect the total cadmium loading of the organism. Acute poisoning acute poisoning is rare, caused by inhaled cadmium smoke, acute pulmonary edema after 24h and longer, if the individual survived the acute phase, later developed into fibrous bronchitis. Chronic poisoning Chronic poisoning occurs in a long-term environment with high concentration of cadmium inhaled air. The clinical symptoms are basically inflammation. Later, there is a degenerative change of the nasopharyngeal mucosa (cadmium cold), kidney damage, and urine protein > 2g/24h. Mainly low molecular weight proteins, such as α1-microglobulin and β2-microglobulin, can be filtered by the glomerulus but cannot be absorbed by the glomerulus. Precautions Due to the different measurement methods and regions, the published reference values ​​are very different, so it is difficult to compare, even with the same method, the normal upper limit is also 3 times different. Inspection process Atomic absorption spectrophotometry. Not suitable for the crowd Generally no taboos. Adverse reactions and risks Generally no complications.
