Home Lead Testing Kits

The U.S. Consumer Product Safety Commission (CPSC) announced the results of a special evaluation of consumer lead test kits. CPSC staff used commonly available test kits on a variety of paints and other products containing different levels of lead. Many of the tests performed using the kits did not detect lead when it was there (false negatives); some indicated lead was present when it was not (false positives). Of 104 total test results, more than half (56) were false negatives, and two were false positives. None of the kits consistently detected lead in products if the lead was covered with a non-leaded coating. Based on the study consumers should not use lead test kits to evaluate consumer products for potential lead hazards. These findings are consistent with previous CPSC staff test results.

Consumers should exercise caution when using these test kits to evaluate consumer products for potential lead exposures. False results can make it difficult or impossible for consumers to determine the proper course of action to take. In fact, CPSC staff has tested a number of other samples that had been identified by consumers and others based on their use of inexpensive test kits as having high lead levels. To date, none of these items has actually had high lead levels based on CPSC lab analysis. This is another indication of the poor reliability of the kits for this purpose. Testing by a qualified laboratory and trained personnel is the only way to accurately assess the potential risk posed by a consumer product that may contain lead.

Consumers can stay informed of lead-related recalls by signing up for email announcements at www.cpsc.gov. Consumers who suspect that their child has been exposed to excessive levels of lead, should immediately contact a physician.
