• Helps confirm adherence to lifestyle abstention or compliance with a company's drug-free mandate.

How It Works

Collection

• Under chain-of-custody, a qualified collector trims a small hair sample, typically from the crown, characterized by efficient documentation processes in Knoxville, AL.
• This sample is then securely sealed, comprehensively labeled, and transported to a certified testing facility.
• If scalp hair is insufficient, collectors might resort to alternate body hair collection sites.

Testing Methodology

• Samples undergo comprehensive washing and preparation to eliminate any potential external contamination.
• Preliminary screening processes apply immunoassay technologies to detect various drug classes.
• Positive initial screenings are thoroughly confirmed using GC/MS or LC/MS/MS techniques for accurate identification.
