The ChildGuard hair test is a specialized drug screening designed to detect drug exposure in children using a small hair sample. It provides a longer [detection window](https://amhnationwide.com/hair-follicle-drug-test-detection-window/) compared to [urine](https://amhnationwide.com/urine-drug-testing/) or saliva tests, typically up to 90 days. This test is used to monitor potential drug use or exposure in a non-invasive manner. USERS ## Who Orders the ChildGuard Hair Test? The ChildGuard hair test is typically ordered by parents, guardians, social service agencies, healthcare providers, or legal entities concerned with a child’s drug exposure. It is used to assess potential drug use or environmental exposure in children when long-term monitoring is needed. Parents or Guardians: To monitor suspected drug exposure. Social Services: For child welfare evaluations. Healthcare Providers: To assess drug exposure related to medical care. Legal Authorities: In custody or court-related cases. DETECTION ## What is the Detection Window for the ChildGuard Hair Test? The ChildGuard hair test can detect drug use or exposure up to 90 days prior to collection. Hair grows about half an inch per month, and the test typically analyzes 1.5 inches of hair closest to the scalp. This long detection window makes it effective for monitoring ongoing exposure or drug use over time. Detection Window: Up to 90 days (3 months). Sample Length: Approximately 1.5 inches of hair. Drugs Detected: Includes common substances such as THC, cocaine, opiates, amphetamines, and PCP. PROCESS ## How is the ChildGuard Hair Test Collected? The ChildGuard hair test collection involves securely cutting a small sample of hair close to the scalp, usually from the crown area. The process is non-invasive and painless. AMH Nationwide routes the sample to one of five national labs: [Quest Diagnostics](https://www.questdiagnostics.com/), [LabCorp](https://www.labcorp.com/), Omega Labs, United States Drug Testing Labs, or ExperTox for analysis. Sample Size: About 100 strands of hair (approx. 50 mg). Collection Site: Local collection sites directed by AMH Nationwide. Handling: Samples are sealed and sent to certified labs. Analysis: Every non-negative result is reviewed by a certified Medical Review Officer. ## Ready to Schedule a ChildGuard Hair Test?
