Arsenic Poisoning Blood Test

What is Arsenic Poisoning?

Arsenic poisoning is a toxic condition that occurs when dangerous levels of arsenic accumulate in the body. It is caused by exposure to inorganic arsenic through contaminated drinking water, occupational exposure, or consumption of contaminated food sources. The Heavy Metals Panel Blood Test is the most important test for diagnosis because it directly measures arsenic concentrations in the bloodstream along with other toxic metals.

What causes arsenic poisoning?

Arsenic poisoning is caused by exposure to toxic levels of arsenic, primarily through contaminated drinking water from wells in areas with high natural arsenic deposits. Other common sources include occupational exposure in industries like mining, smelting, or pesticide manufacturing, consumption of rice grown in contaminated soil, and seafood from polluted waters. Long-term exposure to even low levels of arsenic can accumulate in the body and cause poisoning over time.

What is the best test for arsenic poisoning?

The Heavy Metals Panel Blood Test is the most important test for arsenic poisoning because it directly measures the concentration of arsenic in your bloodstream along with other toxic metals like lead, mercury, and cadmium. This comprehensive panel provides definitive evidence of toxic exposure and helps determine the severity of poisoning. Blood testing is particularly useful for detecting recent acute exposure, while urine testing may also be recommended for evaluating chronic long-term exposure patterns.

When should I get tested for arsenic poisoning?

You should get tested if you experience unexplained gastrointestinal symptoms like severe abdominal pain, persistent nausea, vomiting, or chronic diarrhea, especially if you drink well water or live in an area with known arsenic contamination. Other warning signs include unusual skin changes like darkening or thickening, numbness or tingling in hands and feet, unexplained fatigue, or if you work in high-risk industries like mining or pesticide manufacturing. Testing is also recommended if you regularly consume high-risk foods like rice products or seafood from potentially contaminated areas.

What are the symptoms of arsenic poisoning?
Symptoms of arsenic poisoning vary depending on whether exposure is acute or chronic. Acute poisoning causes severe abdominal pain, vomiting, watery diarrhea, blood in urine, muscle cramping, and abnormal heart rhythms. Chronic exposure leads to skin changes including darkening and thickening of skin, white lines on fingernails, persistent numbness or burning sensations in hands and feet, chronic digestive problems, and unexplained weakness. Long-term exposure can also cause more serious complications like cardiovascular disease and increased cancer risk.
Who is at risk for arsenic poisoning?
People who drink water from private wells in areas with high natural arsenic levels are at highest risk, particularly in regions of the United States like parts of the Southwest, Midwest, and New England. Workers in industries involving mining, metal smelting, wood preservation, or pesticide manufacturing face occupational exposure risks. Those who regularly consume large amounts of rice or rice-based products, live near industrial sites or former orchards treated with arsenic pesticides, or eat seafood from contaminated waters also have increased risk.
What happens if arsenic poisoning is left untreated?
Untreated arsenic poisoning can lead to severe and potentially life-threatening complications. Chronic exposure increases the risk of various cancers including skin, bladder, lung, and liver cancer. Cardiovascular problems like heart disease, high blood pressure, and blood vessel damage become more likely. Neurological damage can cause permanent nerve dysfunction, cognitive impairment, and peripheral neuropathy. Other serious complications include diabetes, liver disease, kidney failure, and respiratory problems. Early detection and removal from the arsenic source are crucial for preventing these long-term health consequences.
Can arsenic poisoning be diagnosed with a blood test?
Yes, arsenic poisoning can be diagnosed with a blood test, specifically the Heavy Metals Panel Blood Test. This test measures the concentration of arsenic in your bloodstream and is particularly effective for detecting recent acute exposure within the past few days. Blood testing provides quick results that help doctors confirm poisoning and begin treatment promptly. For suspected chronic exposure, doctors may also recommend urine testing, which can detect arsenic exposure over a longer time period and provides information about your body's ability to eliminate the toxin.
How is arsenic poisoning treated?
Treatment for arsenic poisoning begins with immediately removing the source of exposure, whether that means switching to safe drinking water, leaving a contaminated work environment, or eliminating contaminated foods from your diet. For acute severe poisoning, chelation therapy using medications like dimercaprol or DMSA may be administered to bind arsenic and help your body eliminate it faster. Supportive care includes intravenous fluids for dehydration, medications to control symptoms like nausea and pain, and monitoring of heart and kidney function. Long-term management involves regular testing to ensure arsenic levels decrease and monitoring for potential complications.
How can I prevent arsenic poisoning?
Prevention starts with testing your water supply, especially if you use a private well, and installing appropriate filtration systems like reverse osmosis or activated alumina filters if arsenic is detected. Diversify your diet to include various grains beyond rice, and rinse rice thoroughly before cooking. If you work in high-risk industries, follow all safety protocols including wearing protective equipment and practicing good hygiene. Avoid living near industrial sites or former agricultural areas that may have arsenic contamination, and be cautious about seafood sources. Regular testing can catch exposure early before serious health problems develop.
What can I do at home for arsenic poisoning?
While medical treatment is essential for arsenic poisoning, supporting your body's detoxification at home can be helpful alongside professional care. Drink plenty of clean, arsenic-free water to help flush toxins from your system. Eat a nutrient-rich diet with foods high in antioxidants like fruits and vegetables, selenium-rich foods like Brazil nuts, and sulfur-containing vegetables like garlic and onions which may support detoxification. Avoid further exposure by eliminating contaminated water and food sources immediately. However, do not attempt to self-treat arsenic poisoning without medical supervision, as severe cases require immediate professional intervention and chelation therapy.

What this means

Your lead level is slightly elevated above the recommended safe range. While not immediately dangerous, this indicates ongoing exposure that should be addressed to prevent accumulation and potential long-term effects on your nervous system, kidneys, and overall health.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More complex tests, such as hormone panels, may take up to 10–15 business days due to their complexity.
