Urinary arsenic (As) provides an indication of recent or ongoing exposure to various forms of the metalloid. Urine As may also indicate, to a lesser extent, endogenous detoxification of inorganic As. The less toxic organic forms of As from seafood have a circulating half-life of about 48 hours, and are rapidly excreted from the body. Consider very recent shellfish consumption with a finding of high urinary As.

Food, well water, and air are common sources of exposure for As. The predominant dietary source of As is seafood, followed by rice/rice-based products, mushrooms, and poultry (antiparasitics in feed). While fish/shellfish contain the highest levels of As, most abundant are the much less harmful organic As species arsenobetaine and arsenocholine; they are rapidly and efficiently excreted.

Arsenic is a natural component of the earth’s crust and is widely distributed throughout the environment in the air, water and land. It is highly toxic in its inorganic form and considered a carcinogenic heavy metal.

Sources:

Found in water, air, soil, cigarettes, and cosmetics. Food grown in contaminated water sources, such as rice and vegetables, or fish, are a common source. Major sources of occupational exposureis the manufacture of pesticides, herbicides, and agricultural products.

90% of all arsenic produced is used as a preservative for wood to prevent rotting and decay. Copper chromated arsenate (CCA), also known as pressure-treated wood, wasphased out for residential use in 2003, but wood treated prior could still be in existing structures. CCA-treated wood is still used in industrial applications. 

Organic arsenic found in seafood is relatively nontoxic, while the inorganic forms are toxic.

Arsenic, a toxic heavy metal, can accumulate in the body. It may be of an organic or inorganic (toxic form) source. High levels cause GI distress, kidney problems, skin, heart and nervous system changes in health.

Arsenic is an element found in nature, and in man-made products, including some pesticides. Arsenic is widely distributed in the Earth’s crust. It is found in water, air, food, and soil.

The "Arsenic, Blood" marker on the "Heavy Metals Profile I, Blood" panel from LabCorp is a crucial test for assessing exposure to arsenic, a toxic heavy metal with significant health implications. Arsenic exposure can occur through various means, including contaminated water, certain foods, industrial processes, and occupational exposure in industries like mining and smelting.

Measuring arsenic levels in blood is essential for detecting recent exposure, as arsenic is rapidly cleared from the bloodstream and redistributed to organs and tissues. Elevated blood arsenic levels can lead to acute symptoms like gastrointestinal distress, cardiac problems, and severe skin manifestations. Chronic exposure, even at lower levels, is particularly concerning, as it can result in long-term health issues like skin lesions, increased risk of cancers (especially skin, bladder, and lung), cardiovascular diseases, and neurotoxicity. For certain forms of organic arsenic, such as those found in seafood, the toxicity is much lower, and these forms are rapidly eliminated from the body; however, inorganic arsenic, found in contaminated water and certain foods, is highly toxic.

Function:

Arthritic peptide, glucose-6-phosphate isomerase, is an endogenous molecule associated with joints. This cytoplasmic enzyme catalyzes the second step of glycolysis and is found at low levels in serum. Arthritic peptide can stimulate KRN T cells when processed and presented by antigen presenting cells.
