What Is a Hair Drug Screen?

Hair testing for drug detection involves analyzing a small portion of hair to trace drugs and their metabolites that have traversed through the bloodstream and lodged in the hair. Slow hair growth coupled with metabolite embedding provides this method among the longest detection periods, making it perfect for exposing habitual or ongoing drug use.

• Generally, 100–120 hair strands clipped close to the scalp (around 1.5 inches) are required.
• The approximate detection window spans 90 days, contingent on hair length.
• A broad spectrum of substances can be identified, such as amphetamines, opioids, cocaine, marijuana, and PCP.

Why Organizations Use Hair Drug Screening

• In Huntsville, TN, pre-employment hair testing is crucial for revealing long-term substance usage habits.
• Hair testing can also be administered randomly or periodically, especially within Huntsville, TN's safety-sensitive industries.
• It is employed to ensure compliance with requirements in treatment or legal monitoring programs.
• Verification of lifestyle abstinence or adherence to a company's drug-free policies is facilitated through routine testing.

How It Works

Collection

• In Huntsville, TN, a hair collector carefully cuts a small sample, often from the crown, ensuring it is under strict chain-of-custody standards.
• The sample is secured, clearly marked, and dispatched to a certified lab for analysis.
• If sufficient scalp hair is lacking, alternative sites such as body hair may be considered.

Testing Methodology

• Samples undergo cleaning and preparation to eliminate any external contaminants.
• The initial screening employs immunoassay methods to identify drug categories.
• Confirmatory tests using GC/MS or LC/MS/MS follow positive screenings for precise identification.
• Cutoff standards are established at nanograms per milligram (ng/mg) in compliance with SAMHSA and laboratory guidelines.

Interpreting Results

• Negative: No substance is detected above the lab-specified cutoff level in Huntsville, TN.
• Positive: A substance or metabolite is identified and verified through secondary rigorous testing.
• Inconclusive/Rejected: Sample quantity may be insufficient, or contamination present, necessitating a reevaluation or recollection.

Detection Windows

Hair drug testing offers the most extended detection window available among drug testing methods. By evaluating a standard 1.5-inch hair sample, approximately 90 days of possible drug exposure can be gleaned. Adding longer hair samples potentially extends the detection window further, contingent on the growth rate, which is about 0.5 inches per month. Differing from urine or oral fluid testing, hair analysis does not capture drug use within the immediate past 7–10 days.
