What Is a Hair Drug Screen?

In Central, TN, hair drug screening involves a meticulous evaluation of a small hair sample to find evidence of drugs and their metabolites that have permeated the bloodstream, now ensconced within the hair shaft. Given hair's slow growth and capacity to retain drug metabolites for extended periods, this method offers perhaps the longest detection windows available, making it well-suited for revealing chronic or long-standing drug use.

• Typically, 100–120 strands are taken close to the scalp, measuring around 1.5 inches, to ensure accurate results.
• Such samples often uncover drug exposure over a period of approximately 90 days, though this can vary with hair length.
• Capable of screening for numerous substances, including amphetamines, opioids, cocaine, marijuana, and PCP.

Why Organizations Use Hair Drug Screening

• Pre-employment hair testing in Central, TN effectively identifies long-term substance use, ensuring a reliable workforce.
• Random or periodic workplace testing is utilized within safety-sensitive industries to maintain consistent safety standards.
• Compliance monitoring for treatment or legal programs may use hair testing to validate program adherence.
• Employers can confirm lifestyle abstinence and adherence to company drug-free policies through this method.

How It Works

Collection

• A collector carefully trims a small hair sample (typically from the crown area) in accordance with chain-of-custody standards in Central, TN.

• The specimen is then sealed, accurately labeled, and sent to a certified laboratory.

• In situations where scalp hair is insufficient, alternate sites like body hair can be used for collection.

Testing Methodology

• Hair samples in Central, TN undergo preparation where they are washed to eliminate possible external contaminants before analysis.
• The initial screening phase in Central, TN utilizes immunoassay methods to identify potential drug classes.
• Positive immunoassay results are confirmed through advanced techniques such as GC/MS or LC/MS/MS for precise verification in Central, TN.
• Central, TN abides by standard cutoff concentrations measured in nanograms per milligram (ng/mg) according to SAMHSA and laboratory specifications.

Interpreting Results

• Negative: Drug/metabolite is not detected above the established laboratory threshold.
• Positive: Detection and confirmation of drug/metabolite takes place through secondary analytical procedures.
• Inconclusive/Rejected: An inadequate sample or contamination necessitates a repeat collection.

Detection Windows

Hair drug tests offer the longest detection timelines, with a typical 1.5-inch hair sample reflecting approximately 90 days of drug use history. Longer hair samples can extend this window, contingent on the growth rate, generally estimated at about 0.5 inches monthly. Unlike urine or oral fluid analysis, hair testing does not detect very recent drug use, particularly within the past 7–10 days.

Considerations for Regulated and Non-Regulated Testing:

• The Department of Transportation (DOT) currently excludes hair testing mandates, though guidelines remain under review.
• Non-DOT programs appreciate hair testing's efficacy as a long-term detection resource.
• Collections should reflect professional training and exhibit a documented chain-of-custody.
• Reliability and accuracy are ensured through laboratory certifications under SAMHSA or CAP/CLIA.
