What Is a Hair Drug Screen?

Hair drug screening analyzes meticulously collected strands of hair, enabling the detection of drugs and metabolites once circulated through the bloodstream and embedded within the hair shaft. Owing to the slow growth rate of hair, accompanied by its metabolite retention over several months, this method offers an extended window of detection, proving effective for identifying chronic or long-term substance usage.

• A typical test requires 100-120 strands cut near the scalp (approximately 1.5 inches in length).
• This sample reflects a detection period of around 90 days, contingent on hair length.
• The test is capability-rich, detecting a broad spectrum of substances such as amphetamines, opioids, cocaine, marijuana, and PCP.

Why Organizations Use Hair Drug Screening

• In Norris, TN, pre-employment hair screening is undertaken to analyze prolonged substance use.
• In safety-sensitive sectors, random or scheduled workplace testing offers periodic occupational assessments.
• Monitoring compliance in therapeutic or judicial initiatives is maintained through hair drug screening.
• Companies can utilize it to confirm abstinence or adherence to drug-free policies.

How It Works

Collection

• A collector professionally trims a small hair sample, usually from the crown, under strict chain-of-custody conditions.
• The collected sample is then safely sealed, labeled, and sent to a certified lab for testing.
• If scalp hair is unavailable, alternative body hair may be used.

Testing Methodology

• Samples undergo cleaning and preparation to eliminate any external contaminants.
• The initial screening employs immunoassay methods to identify drug categories.
• Confirmatory tests using GC/MS or LC/MS/MS follow positive screenings for precise identification.
• Cutoff standards are established at nanograms per milligram (ng/mg) in compliance with SAMHSA and laboratory guidelines.

Interpreting Results

• Negative: In Norris, TN, results indicate no detection of drugs or metabolites above the laboratory's threshold level.
• Positive: The presence of drugs or metabolites is confirmed through secondary testing.
• Inconclusive/Rejected: Insufficient sample provision or contamination necessitates sample recollection.

Detection Windows

Hair drug testing stands out with the most extensive detection window among drug testing methods. Using a standard 1.5-inch segment of hair, potential drug exposure spanning roughly 90 days is assessed. Given the approximate hair growth rate of half an inch per month, longer samples can prolong detection periods. However, unlike other testing forms like urine and oral fluid testing, it doesn't identify recent use within the past 7-10 days.

Essential Aspects for Regulated and Non-Regulated Testing

• Despite the DOT not mandating hair testing, Norris, TN remains attentive to evolving guidelines potentially considering its adoption.
• In non-DOT scenarios, hair testing is recognized for its efficacy in detecting prolonged drug exposure.
• Trained and qualified personnel must execute sample collection under strict chain-of-custody protocols.
• Laboratories involved should adhere to SAMHSA or CAP/CLIA-accredited standards to ensure dependability and precision.

Benefits

• In Norris, TN, hair testing offers an extended window of detection (up to 90 days or even longer).
• Compared to urine samples, hair specimens pose a greater challenge for adulteration or substitution.
• It effectively reveals consistent patterns of chronic or repeated drug usage.
• The collection process is rapid, non-invasive, and eliminates the necessity for facilities like restrooms.
