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 Purcellville, VA.

• 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

• Pre-employment hair testing in Purcellville, VA effectively identifies long-term substance use, ensuring a reliable workforce.
• Random or periodic workplace testing is utilized within safety-sensitive industries to maintain consistent safety standards.

• In Purcellville, VA, a qualified individual trims a small sample, usually from the crown area, while adhering to chain-of-custody protocols.
• Once collected, the sample is securely sealed, labeled, and sent to a certified laboratory in Purcellville, VA.
• If scalp hair is inadequate, alternative collection sites such as body hair may be utilized.

Testing Methodology

• Extensive washing and preparation of samples are done to eliminate any external contamination.
• Initial screening employs immunoassay technology to detect various drug classes in Purcellville, VA.
• Positive screens undergo confirmation through GC/MS or LC/MS/MS testing for precise identification.
• Defined cutoff levels are maintained in nanograms per milligram (ng/mg) following SAMHSA and laboratory standards.

Interpreting Results

• Negative: No drugs or metabolites are detected above defined laboratory cutoff levels.
• Positive: Drug/metabolite presence confirmed after additional secondary testing procedures.
• Inconclusive/Rejected: Lack of sample sufficiency or presence of contamination necessitating another collection.

Detection Windows

Hair testing, used in Purcellville, VA, provides the broadest detection window among drug testing methods. A typical 1.5-inch hair sample can depict up to 90 days of potential drug activity. Greater hair lengths might expand this testing window further, contingent on growth rates (roughly half an inch a month).
