What Is a Hair Drug Screen?

Hair drug screening involves the examination of a small hair sample to discover drug and metabolite presence, substances which travel through the bloodstream and settle in the hair shafts. Due to the slow growth rate of hair, metabolites are retained for months, providing one of the most extended detection periods compared to other testing techniques making it ideal for identifying habitual or prolonged substance use, a notable advantage for regions such as Puryear, TN focused on maintaining workplace integrity.

• Generally, a collection of 100-120 strands near the scalp, roughly 1.5 inches in length, is required for optimal testing accuracy.
• This length provides insight into approximately a 90-day timeline of possible drug use, contingent on hair growth.
• The test can identify a multitude of substances, including amphetamines, opioids, cocaine, marijuana, and PCP.

Why Organizations Use Hair Drug Screening

• In Puryear, TN, pre-employment hair screening is undertaken to analyze prolonged substance use.
• In safety-sensitive sectors, random or scheduled workplace testing offers periodic occupational assessments.
• Monitoring compliance in therapeutic or judicial initiatives is maintained through hair drug screening.
• Companies can utilize it to confirm abstinence or adherence to drug-free policies.

How It Works

Collection

• During collection, a qualified collector trims a small sample, typically from the crown area, following strict chain-of-custody procedures to ensure reliable results.
• The harvested sample is then sealed, labeled, and dispatched to a certified laboratory for analysis.
• If scalp hair is unavailable, alternate collection sites, such as body hair, may be used.

Testing Methodology

• In the Puryear, TN, samples undergo a cleaning process to remove any external contaminants prior to analysis.
• Initial screening employs immunoassay techniques to identify different drug categories.
• Upon yielding positive screening results, further validation is conducted using GC/MS or LC/MS/MS methodologies for precise substance identification.
• Established cutoff levels are defined in ng/mg, following SAMHSA and other pertinent laboratory guidelines.

Interpreting Results

• Negative: Drug or metabolites are not present above the laboratory's cutoff threshold.
• Positive: Drugs or metabolites are detected and verified through confirmatory tests.
• Inconclusive/Rejected: Either insufficient sampling or contamination necessitates recollection.

Detection Windows

In Puryear, TN, hair analysis offers the most extended drug detection window compared to other testing methods. A standard hair sample measuring 1.5 inches typically reflects up to 90 days of potential drug exposure.
