Whole blood arsenic (As)

The total amount of arsenic in adults is 15-20 mg, which is mainly distributed in hair, nails, bones and skin. Arsenic entering the body is first transformed in the blood and then distributed to the whole body tissues. The arsenic in the body is mainly excreted from the urine. Arsenic poisoning is related to the strong binding of arsenic to sulfhydryl groups in the body, which inactivates a large number of thiol-containing enzymes. Thereby hindering the biochemical metabolism of the cells and significantly reducing the body's antioxidant capacity. Basic Information Specialist classification: growth and development examination classification: blood examination Applicable gender: whether men and women apply fasting: fasting Analysis results: Below normal: Rare. Normal value: Whole blood arsenic (As): 0.03-0.82 μmol/L Above normal: Acute and chronic arsenic poisoning, skin cancer, etc. negative: Positive: Tips: The concentration of arsenic in the urine is expressed as total arsenic (completely burned out) and must be distinguished from those of non-toxic organic arsenic (fish arsenic), arsenic metabolites or inorganic arsenic. Normal value Spectrophotometry (AAS) The total amount of the body is 14-21 mg; Whole blood 0.03 ~ 0.82μmol / L (0.2 ~ 6.2μg / dl); Chronic poisoning (whole blood) 1.33 ~ 6.65μmol / L (10 ~ 50μg / dl); Acute poisoning 7.89 ~ 12.37μmol / L (60 ~ 93μg / dl). Clinical significance Increase acute and chronic arsenic poisoning, skin cancer, etc. High results may be diseases: arsenic poisoning, arsenic poisoning in children, skin cancer precautions The concentration of arsenic in urine is expressed as total arsenic (completely burned out) and must be distinguished from non-toxic organic arsenic (fish arsenic), arsenic metabolites or inorganic arsenic, which is a free form of arsenic, more precisely Is a toxic form of arsenic. Inspection process Atomic absorption spectrophotometry using flameless hydride techniques. Neutron activity analysis is the most stable and accurate method because it does not require pretreatment of the sample and the detection range is very low. Not suitable for the crowd No taboos. Adverse reactions and risks No complications.
