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.

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.

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.

Antibodies Appear:

Mixed Connective Tissue Disease [1]

Osteoarthritis [2]

Rheumatoid Arthritis [1, 2, 3]

Known Cross-Reactions:

gliadin, dairy proteins, pork [4]

Function:

Saccharomyces cerevisae, baker’s yeast, contains Chl1p, a putative helicase with human homologs (antiSaccharamyces cerevisae antibody – ASCA), which is required for DNA repair, recombination, transcriptional silencing and aging. Anti-neutrophil cytoplasmic antibodies (ANCAs) are a group of autoantibodies against antigens in the cytoplasm of neutrophil granulocytes and monocytes.

Antibodies Appear:

Behçet’s Syndrome with GI Involvement

Crohn’s Disease

Long-term use of Anti-Thyroid Medication

Ulcerative Colitis5 Vasculitis

Ascaris is a worm that infects the small intestine, but its life cycle includes migration through the circulation to the heart and lungs, and into the oropharynx. Infection is acquired through the ingestion of embryonated eggs in contaminated soil or water. Ascariasis is the most prevalent intestinal helminth infection in the world; current estimates suggest that more than 1 billion persons are infected. In the US, infection is more common in rural parts of the southeast.

Most individuals have no noticeable symptoms. Migrating larvae may produce “verminous pneumonia”. However, heavy infection, especially in children, may produce abdominal cramps, and a mass of tangled worms may cause intestinal obstruction. Aberrant migration of individual adult worms occasionally leads to obstructions resulting in cholangitis, cholecystitis, liver abscess, pancreatitis, appendicitis, or peritonitis.

Ascaris lumbricoides, an intestinal roundworm, is one of the most common helminthic human infections worldwide.

Ascaris lumbricoides is the largest intestinal nematode of man. The female worms are larger than the males and can measure 40 cm in length and 6 mm in diameter. They are white or pink and are tapered at both ends. 

Ascorbic Acid is a natural water-soluble vitamin (Vitamin C). Ascorbic acid is a potent reducing and antioxidant agent that functions in fighting bacterial infections, in detoxifying reactions, and in the formation of collagen in fibrous tissue, teeth, bones, connective tissue, skin, and capillaries.
