In-home analysis is the most effective form of lead testing, as it's carried out by qualified specialists in a controlled laboratory setting. As a general rule, the higher the lead content in the test surface, the darker the final color will be. If the swab doesn't change color, it means no lead has been detected and you can check that surface or material off of your list. If you have small children or pets who could find their way into the trash, deposit your testing materials in an outdoor receptacle a safe distance from your home. When the 2 test solutions are mixed, lead-tainted paint will cause them to take on a dull yellow color. Compare the color of the solution to the test standard on the vial.
With oral agents like Chemet , the standard course of treatment is 14 days with an additional course if needed. Symptoms of lead encephalopathy may be treated with anticonvulsants, steroids, and a diuretic drug called Osmitrol . In cases of acute contamination , whole bowel irrigation, endoscopy, or surgery may be used. Lead encephalopathy occurs when lead penetrates the membrane surrounding the brain and starts breaking down tissues. Symptoms include the loss of muscle control, an altered mental state, delirium, and seizures.
Jobs and Careers
A healthcare provider may order a venous blood draw to confirm the blood lead level seen in a test. The table below shows when a child with lead in their blood should receive a venous blood draw to confirm their blood lead level. A blood lead test is the best way to find out if a child has lead poisoning.
The CDC has updated the blood lead reference value to 5 μg/dL. Pediatricians should screen for lead in all non-Medicaid children in the absence of local and state guidelines. These are lines of increased density on the metaphysis of the bone, showing radiological growth retardation. This is not a routine procedure to identify lead poisoning, but a radiological finding of chronic exposure. However, because these results are not specific to lead exposure, the CBC test is not as valuable for detecting lead exposure as the BLL and EP assays.

It can damage your child’s nervous system, brain and other organs. Lead poisoning can also lead to severe health, learning and behavioral problems, including sudden brain damage and long-term intellectual deficits. The table below shows hazard levels of lead in paint, soil and dust, as determined by the California Department of Public Health . Department of Housing & Urban Development may have different hazard level definitions.
Chew on windowsills, furniture, door frames and other items covered with lead-based paint. Find out about everyday things you can do to prevent lead poisoning. Your house is near a freeway or busy roadway where leaded gasoline and its exhaust may have polluted the soil with lead. CDC’s Milestone Tracker app – available in English and Spanish, is a free tool to help you monitor your children’s developmental progress. The intravenous chelating agent dimercaprol cannot be used in people with a peanut allergy.

Many private insurance policies cover the cost of testing for lead in the blood. The cost of blood lead testing for children enrolled in Medicaid is covered by the Centers for Medicare & Medicaid Services. Lead poisoning happens when your child is exposed to high amounts of lead.
You may require more than one treatment of EDTA to remove lead from your body. Undergo these treatments if you have a severe case of lead poisoning, but be aware that it may not be possible to reverse damage. Persons living in developing countries are at a higher risk because these places often have less stringent laws on lead exposure. Living in older homes can expose you to lead paints, which were banned in the 1970s.

Your best option will be to call a qualified professional to come out and inspect your home. The test strip will slowly begin to change colors if lead is detected in the surrounding water. Many of the leading testing kits on the market claim to provide clear, easy-to-interpret results within 5-10 minutes. Add 5 drops of Solution 2 to the vial and shake it again. Squeeze the dropper bottle slowly and carefully to ensure that you've added the right amount of the reagent solution. Whisk the solution back and forth for 10 seconds as you did the first time.
Compare the color of the test strip to the included color chart. Once time is up, remove the test strip and hold it up alongside the color chart included with the product you're using to determine whether the resulting hue indicates an unsafe amount of lead. With most tests, a positive result is represented by a yellow color. This means it's possible that the water in your home could contain some concentration of lead that doesn't show up in the test.
The EPA recommends that only certified professionals use these kits. The professional can also perform a risk assessment, which alerts you to any hazards or problem areas with the lead in your home. However, NIOSH recommends that the most current guidelines for management of lead exposed adults be implemented by the medical community at the current CDC/NIOSH reference BLL of 5 µg/dL .
As beneficial as chelation therapy is, it does carry risks. To this end, speak with a specialist, such as a medical toxicologist, to get a better understanding of whether chelation therapy is safe and appropriate for you as an individual. Surgery and other specialist procedures may be used if a prominent lead source is found in the digestive tract or elsewhere in the body.
Lead exposure is more likely in certain homes and environments than in others. This includes older buildings that may have used lead paint or poorer communities that may not have replaced outdated lead water pipes. Certain industries also place employees at an increased risk of lead exposure. For persons with lower levels of lead in the body, removing the contaminant may be enough to reduce blood lead levels. Finding out about lead in your water is only one part of the solution. Lead enters our bodies from many common contaminated sources other than drinking water, such as dust, soil and air.
