What Is a Hair Drug Screen?

In Dickson, TN, hair drug analysis involves examining a small segment of hair to reveal drug presence along with their metabolites, which have circulated in the bloodstream and been embedded in the hair shaft. Given hair's slow growth and its capacity to store drug residues over time, it offers one of the longest detection windows available, making it particularly useful in identifying habitual or prolonged substance use.

• This typically involves cutting 100–120 strands near the scalp, spanning about 1.5 inches.
• This sample generally covers approximately a 90-day detection span, adjusted by hair length.
• It is capable of detecting a vast array of substances, including amphetamines, opioids, cocaine, marijuana, and PCP.

Why Organizations Use Hair Drug Screening

• In the state of Dickson, TN, hair testing aids in identifying prolonged substance use during pre-employment screenings.
• Used in randomized or periodic testing within workplace settings, particularly in industries sensitive to safety concerns.
• Monitoring for compliance within treatment or legal programs.
• Affirms lifestyle abstinence or adherence to organizational drug-free policies.

How It Works

Collection

• Dickson, TN collectors obtain a small hair sample (typically from the crown) under strict chain-of-custody protocols to ensure test integrity.
• Each sample is sealed, precisely labeled, and sent to a certified laboratory for thorough analysis.
• When scalp hair is unavailable, alternative collection sites, including body hair, may be utilized to ensure comprehensive testing.

Testing Methodology

• In Dickson, TN laboratories, samples are prepped by washing to eliminate external contaminants.
• Initial testing employs immunoassay techniques to identify broad drug classes.
• If a positive indication arises, confirmatory testing, such as GC/MS or LC/MS/MS, is employed for precise identification.
• Cutoff levels, expressed in nanograms per milligram (ng/mg), align with SAMHSA and laboratory criteria.

Interpreting Results

• Negative: The sample does not show levels of drugs or metabolites exceeding the laboratory's cutoff benchmarks.
• Positive: Presence of drugs or metabolites is confirmed through detailed secondary testing.
• Inconclusive/Rejected: If sampling is insufficient or contamination is detected, recollection may be required.

Detection Windows

Hair drug testing offers the most extended detection window available among drug testing methods. By evaluating a standard 1.5-inch hair sample, approximately 90 days of possible drug exposure can be gleaned. Adding longer hair samples potentially extends the detection window further, contingent on the growth rate, which is about 0.5 inches per month. Differing from urine or oral fluid testing, hair analysis does not capture drug use within the immediate past 7–10 days.

Key Considerations for Regulated and Non-regulated Testing in Dickson, TN

• Although DOT guidelines presently do not mandate hair testing, continuous reevaluation of regulatory guidelines by the Department of Transportation and HHS may influence future directives.
• For non-DOT programs, hair testing is recognized as an effective tool for long-term detection.
• The collection should be entrusted to well-trained and qualified personnel to ensure proper chain-of-custody documentation.
• Labs employed should possess SAMHSA, CAP, or CLIA certification to guarantee result accuracy and dependability.
