What Is a Hair Drug Screen?

Hair drug testing entails analyzing a small segment of hair to unearth drug substances and their metabolites that have integrated into the hair shaft after circulating through the bloodstream. As hair grows at a measured pace and retains drug metabolites for an extended duration, it offers the longest detection window among testing measures, making it optimal for identifying ongoing or recurrent use of substances, even in Greeneville, TN.

• Normally entails the collection of 100–120 strands, trimmed close to the scalp, measuring around 1.5 inches long.
• Generally signifies a 90-day detection period based on hair length.
• Has the capacity to test for a broad spectrum of substances, such as amphetamines, opioids, cocaine, marijuana, and PCP.

Why Organizations Use Hair Drug Screening

• In Greeneville, TN, hair testing aids pre-employment assessments by identifying prolonged substance use.
• Periodic or random workplace tests in industries sensitive to safety considerations are enhanced by this testing method.
• Facilitates compliance monitoring within legal or treatment program requirements.
• Confirms adherence to drug abstinence lifestyles or company-enforced, drug-free policies.

How It Works

Collection

• A certified collector trims a small section of hair (typically from the crown) in accordance with strict custody regulations.
• The sample is sealed, marked, and sent to a certified laboratory.
• If scalp hair is not available, alternative areas, such as body hair, may be utilized.

Testing Methodology

• Collected samples undergo a cleansing and preparatory process to dispel external contaminants.
• The initial screening is undertaken using immunoassay technology to identify drug classes present.
• For any positives recorded, confirmatory testing through methods like GC/MS or LC/MS/MS is employed for accurate identification.
• Cutoff thresholds, gauged in nanograms per milligram (ng/mg), are established based on SAMHSA and laboratory standards.

Interpreting Results

• Negative: Within Greeneville, 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 Greeneville, TN, hair testing offers the longest detection capability among drug testing methods. A standard 1.5-inch hair sample provides insights into approximately 90 days of drug exposure potential. Longer hair may extend the detection potential further, contingent on hair growth rates, typically about 0.5 inches per month.
