What Is a Hair Drug Screen?

In Lenoir City, TN, hair drug testing involves analyzing a small hair sample to detect drugs and their metabolites that have entered the hair shaft through the bloodstream. Given the gradual growth of hair, which preserves drug metabolites over time, this method provides one of the longest detection periods, optimal for identifying long-term or habitual substance use.

• Usually, around 100–120 strands are cut close to the scalp, approximately 1.5 inches in length.
• This sample size generally covers about a 90-day detection window, dependent on hair growth.
• The method allows testing for various substances such as amphetamines, opioids, cocaine, marijuana, and PCP.

Why Organizations Use Hair Drug Screening

• Utilization for pre-employment screening to profile long-term substance use habits.
• Implementing random or periodic workplace tests in industries with heightened safety demands.
• Enabling compliance verification in treatment programs or legal obligations executed in Lenoir City, TN.
• Serving as a means of confirming adherence to lifestyle abstinence or company-imposed drug-free policies.

How It Works

Collection

• Under chain-of-custody standards in Lenoir City, TN, a collector trims a small hair sample, usually from the head's crown.
• The sample is sealed, labeled, and dispatched to a certified laboratory.
• If head hair is unavailable, other body sites may provide alternative collection options.

Testing Methodology

• Upon receiving the sample in Lenoir City, TN, it's cleansed and prepared to eliminate potential external contaminants.
• Initial screening is conducted using immunoassay technology to detect various drug classes.
• If results are positive, confirmatory testing is conducted using advanced techniques like GC/MS or LC/MS/MS for precision in analysis.
• Cutoff levels are determined in nanograms per milligram (ng/mg) in alignment with SAMHSA and lab standards.

Interpreting Results

• Negative: In Lenoir City, TN, no drugs or metabolites detected beyond the laboratory's predetermined cutoff levels.
• Positive: Drugs or metabolites are identified and validated through secondary testing methods.
• Inconclusive/Rejected: Issues like insufficient hair sample or contamination require recollection.

Detection Windows

In Lenoir City, TN, hair testing provides the most extended detection window among drug testing techniques. A typical 1.5-inch hair sample delineates approximately 90 days of potential drug exposure.
