Adult & Child Drug Testing Lab
Hair Exposure Drug Testing (ChildGuard®)

Ensure you’re always ready to meet your communities’ drug testing needs. Start using ChildGuard®, the first drug test designed to detect passive exposure to native drugs and drug metabolites in hair specimens.
ChildGuard® can provide evidence of substance exposure in a child’s environment for up to approximately 3 months and can be performed on donors of any age.
Environmental exposure in this context is 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,
- Unintentional or intentional ingestion of the drug(s).
From 2020-2023, fentanyl exposure in children under 6 increased 349% — An increase of 5,290% since 2016. (www.poisoncenters.org)
Dr. Nora Volkow, head of the National Institute of Drug Abuse, said people are often consuming fentanyl “unbeknownst to them,” resulting in a spike of overdose deaths. Most people are taking fentanyl unknowingly as it’s mixed with other drugs. Drug traffickers are mixing fentanyl with other drugs, including heroin, cocaine, methamphetamine, and MDMA, because it takes little to produce a high, making it a cheap option. Read more here.
