whole blood chromium

The total amount of chromium in adults is about 6 mg. Chromium is absorbed by the intestines and enters the plasma to bind to the transferrin, transporting the chromium to the liver and the body. Chromium is mainly discharged from the urine. Chromium can increase the breakdown and excretion of cholesterol, lower blood cholesterol, and prevent the formation of arteriosclerosis. Chromium is also an effective component of the glucose tolerance factor (functioning to assist insulin in the use of glucose). Therefore, the chromium content in the body is negatively correlated with the incidence of cardiovascular disease. The protective effect of chromium on cardiovascular is related to its involvement in sugar and lipid metabolism. Basic Information Specialist classification: growth and development check classification: biochemical examination Applicable gender: whether men and women apply fasting: fasting Tips: Care should be taken to adjust the instrument so that the beam of the background corrector overlaps the beam of the hollow cathode lamp. Normal value Spectrophotometry (AAS) whole blood <13.4 μmol/L, serum <2.7 μmol/L. Clinical significance (1) Increase chromium poisoning and lung cancer. (2) reduce pregnancy, type 1 diabetes, hyperlipidemia. Precautions When AAS is used for B-Pb measurement with continuous background correction, sometimes the analysis result is low, or the analysis signal is lower than the baseline. This is generally caused by the interference caused by the unaligned light source. Care should be taken to adjust the instrument so that the beam of the background corrector overlaps the beam of the hollow cathode lamp. Inspection process Sample measurement: After thoroughly mixing K2EDTA anticoagulated venous blood or peripheral blood, 50 μl, 450 μl of matrix modifier solution was added and mixed. When manual injection, 12μl was injected into the graphite furnace; when using the automatic injection method, the autosampler automatically sucked 12μl of mixed diluted blood sample into the graphite tube platform. According to the set instrument operating conditions, read the integral absorbance value (As) of each tube. Not suitable for the crowd Generally no taboos. Adverse reactions and risks Discomfort: There may be pain, swelling, tenderness, and visible subcutaneous ecchymosis at the puncture site.
