What Is a Hair Drug Screen?

In Shepherd, TN, hair drug screening involves the examination of a small hair sample to diagnose the presence of drugs and their metabolites that have permeated the bloodstream and been captured in the hair shaft. Due to the gradual rate of hair growth and its ability to store drug metabolites for extended durations, this method offers one of the most protracted detection windows among all testing strategies ideal for pinpointing chronic or long-term drug use.

• Generally demands 100–120 hair strands cut close to the scalp, approximately 1.5 inches in length, for analysis.
• Covers about a 90-day period for potential drug exposure, contingent upon the sample length.
• Capable of screening for a broad assortment of substances including amphetamines, opioids, cocaine, marijuana, and PCP.

Why Organizations Use Hair Drug Screening

• Utilized for pre-employment screening to identify habitual substance use over the long term in Shepherd, TN.
• Employed in random or scheduled workplace testing within safety-sensitive fields.
• Useful for compliance checks in treatment programs or legal obligations.
• Helps in confirming the maintenance of a substance-free lifestyle or adherence to organizational drug-free policies.

How It Works

Collection

• In Shepherd, TN, the collection process involves trained collectors trimming a small sample from the crown of the head, under strict chain-of-custody procedures.

• The sample obtained is then appropriately sealed and labeled before being forwarded to a certified laboratory for analysis.

• In scenarios where scalp hair is unavailable, alternate sites like body hair may be considered for sample collection.

Testing Methodology

• In Shepherd, TN, hair samples receive washing and preparation to eliminate external contaminants.
• Immunoassay technology is initially utilized for screening and detecting broad drug categories.
• Unified, confirmatory testing using GC/MS or LC/MS/MS fortifies positive sample identification.
• Established cutoff concentrations are defined in nanograms per milligram (ng/mg), adhering to SAMHSA and laboratory standards.

Interpreting Results

• Negative: Within Shepherd, TN, no drug or metabolite levels meet or surpass the laboratory's cutoff threshold.
• Positive: Drug or metabolite presence is affirmed through follow-up testing processes.
• Inconclusive/Rejected: In scenarios of insufficient sample quantity or contamination, rediscovery might be necessary.

Detection Windows

In Shepherd, TN, hair drug testing yields the broadest detection window of all drug testing methodologies. A standard 1.5-inch hair sample reflects drug exposure over approximately 90 days. Longer samples can further extend this timeframe, considering the expected hair growth rate of about 0.5 inches per month. Unlike its urine or oral fluid counterparts, hair analysis does not recognize recent drug use within the past week to ten days.

Key Considerations for Regulated and Non-Regulated Testing

• Despite current DOT regulations not mandating hair testing, both the Department of Transportation and HHS are evaluating potential inclusions.
• Non-DOT programs recognize hair tests as a potent long-term detection mechanism.
• Samples should be collected by trained, proficient personnel under strict chain-of-custody protocols.
• SAMHSA or CAP/CLIA accredited laboratories must conduct analyses to ensure precision and reliability.
