Arsenic Urine Test

Arsenic test is performed on a sample of random urine to measure level of Arsenic in the sample.It is performed to substantiate Arsenic Poisoning and also throughout treatment and once treatment of Arsenic Poisoning is over. Arsenic is present in a number of different forms; organic forms are nontoxic in nature while inorganic forms are toxic in nature. As arsenic is excreted mainly by glomerular filtration, test for arsenic in urine is the most effective screening test to measure arsenic exposure.

For correct results, most laboratories conduct the urine check for arsenic using samples collected over a period of 1 or 2days. This provides a clearer image of what quantity arsenic is absorbed and processed by the body. Consumption of seafood before collection of a urine specimen for arsenic testing is probably going to lead to a report of an elevated concentration of arsenic found within the urine, which might be clinically misleading. High concentrations of gadolinium and iodine are well-known to interfere with most metals tests. If either gadolinium or iodine containing contrast media has been administered, a specimen mustn't be collected for ninety-six hours.

As mentioned above, the test is used to measure arsenic in the urine sample. Normally, humans consume five to thirty-five micrograms of arsenic on a daily basis as a part of their traditional diet; thus, traditional urine arsenic output is <35 mcg/specimen. After a seafood meal (seafood contains a nontoxic, organic variety of arsenic), the urine output of arsenic could increase to three hundred mcg/specimen for one day, after that it’ll decline to < 35 mcg/specimen.

This test is a on the spot urine test. Once the urine sample is collected, there are many laboratory ways to check for levels of arsenic. Several of those will separate the varied sorts of organic and inorganic arsenic by identifying certain metabolites like methylarsonic acid (MMA) and dimethylarsinic acid (DMA). The ultimate results are expressed strictly in terms of the harmful inorganic arsenic.
