What Is a Hair Drug Screen?

Hair drug screening analysis involves testing a small sample of hair to determine the presence of drugs and their metabolites. These substances, after circulating through the bloodstream, become integrated into the hair shaft. Given its slow growth, hair retains drug metabolites over extended durations, offering one of the most prolonged detection windows among testing methods, making it ideal for chronic or prolonged drug use assessment, even within San Mateo, CA.

• The typical sample size involves collecting approximately 100 to 120 strands cut as close to the scalp as feasible, measuring around 1.5 inches in length.
• This provides detection coverage for about a 90-day period, contingent on hair length and growth rate.
• Capable of identifying a wide array of substances, including amphetamines, opioids, cocaine, marijuana, and PCP.

Why Organizations Use Hair Drug Screening

• In San Mateo, CA, hair drug testing is highly effective for pre-employment screening purposes to determine long-term substance use.
• Its application is prevalent in random or periodic workplace testing, particularly in safety-sensitive sectors.
• This testing method is essential in compliance monitoring for treatment or sanctionary programs.
• It confirms adherence to lifestyle ambivalence or alignment with company drug-free directives.

How It Works

Collection

• In San Mateo, CA, the collection procedure involves carefully trimming a small hair sample (commonly from the crown region) while adhering to strict chain-of-custody protocols.
• These samples are then sealed, accurately labeled, and dispatched to an accredited laboratory for further examination.
• Should scalp hair be insufficient, alternative sites such as body hair may be utilized for collection.

Testing Methodology

• In San Mateo, CA, hair samples are cleaned to remove any external contaminants before analysis.
• Initial screens employ immunoassay technology for detecting various drug categories.
• For those tests yielding positive preliminary results, verification through GC/MS or LC/MS/MS testing yields precise identification.
• Cutoff levels are defined as measured in nanograms per milligram (ng/mg), conforming to SAMHSA and laboratory guidelines.

Interpreting Results

• Negative: Indicates absence of drug/metabolite at levels above the laboratory's established cutoff, confirming non-use.
• Positive: Indicates presence of drug/metabolite as confirmed by secondary testing, denoting substance exposure.
• Inconclusive/Rejected: May result from insufficient sample size or contamination, necessitating recollection for definitive results.

Detection Windows

In San Mateo, CA, hair testing offers the longest detection period among various drug testing methods. A typical sample of 1.5-inch hair represents approximately 90 days of potential drug exposure, with longer samples extending this window based on the growth rate (~0.5 inches/month). However, hair testing does not capture very recent use (usually within the past 7–10 days).

Key Considerations for Regulated and Non-Regulated Testing

• Currently, DOT guidelines don't mandate hair testing, though evaluations continue by the Department of Transportation and HHS for future potential inclusion.
• For non-DOT programs, hair testing remains a trusted long-term detection option.
• In San Mateo, CA, collection must be done by trained personnel, maintaining documented chain-of-custody.
• Ensure labs are SAMHSA or CAP/CLIA-certified for accuracy and dependability.

Benefits

• Hair testing offers a long detection span, reaching up to 90 days or possibly more.
• Compared to urine specimens, it's challenging to alter or switch.
