ChildGuard is the only drug test designed to detect passive exposure to drugs, distinguishing between both native drugs and drug metabolites in hair specimens. Drug metabolites are produced in the body only if drugs have been ingested. Children in drug-exposed environments are most often not using substances themselves, so drug metabolites are typically absent when a child is being tested for drug exposure. Typical hair tests with other labs will only report a positive exposure result if drug metabolites are detected, even when the native drug is in the child’s hair specimen. ChildGuard reports a positive result if either native drugs or drug metabolites are detected, giving much better insight into the child’s environment. ChildGuard can provide evidence of substance exposure in a child’s environment for the past 3 months and can be performed on donors of any age.


A positive ChildGuard test result suggests that the donor has experienced one or more of the following:


  • Contact with drug smoke,
  • Contact with sweat or sebum (skin oil) of a person in active use,
  • Contact with the actual drug,
  • Accidental or intentional ingestion of the drug(s).
