Chronic lead exposure in young children most often occurs in the home environment. Although elevated levels of lead in the blood often present without any obvious acute symptoms, long term complications such as low IQ and poor academic performance may occur. The best way to evaluate for elevated levels is through a blood test. This blood test is not typically performed on every child unless they are at high risk for exposure to lead. Based on guidance from the Centers for Disease Control & Prevention (CDC), the normal reference range for blood lead levels is less than 3.5 mg/dL. Levels elevated above 3.5 mg/dL indicate an increased need to limit a child’s exposure to lead in an effort to bring this number back down. Treatment for lead poisoning (called “chelation therapy”)  is not typically initiated until the blood level is 45 mg/dL or higher. 

Living in a home built before the year 1978 is one risk factor for lead exposure. If the home your child lives in was built before this time, it may be beneficial to speak with the local health department about testing paint and dust for lead. Renovations and home projects in these older houses can increase lead exposure to the occupants; therefore, children should avoid areas where work on the home is taking place. If a parent’s job exposes them to lead, they should wipe their feet and remove their shoes before entering the home. Parents exposed to lead should also consider changing their clothes and showering before having close contact with their child. Older toys and jewelry can also be sources of lead exposure; the Consumer Product Safety Commission's Website can be used to monitor recalls of toys that may pose a risk to children. 

If you have concerns about your child and lead exposure, contact our office to schedule an appointment and discuss monitoring and testing. For additional information about decreasing lead exposures, read this article from Healthy Children.
