Hair Follicle Drug Testing - Archie, LA

What it is, How it works

Hair tests have become recognized as an effective method for identifying alcohol and drug usage. Hair captures a long-term record of alcohol and drug consumption by embedding biomarkers within the fibers of the hair as it grows. When taken from near the scalp, hair can offer an approximate three-month detection period for alcohol and drugs. Collecting hair is straightforward, relatively resistant to tampering, and simple to transport.

A hair sample measuring 1.5 inches, comprising around 200 strands (akin to the thickness of a #2 pencil), sourced nearest to the scalp will yield 100mg of hair, which is optimal for screening and validation. For EtG, additional screenings, and/or tests exceeding 10 panels, a 150mg sample is advised. Using a jeweler’s scale to weigh the specimen is recommended. In the absence of scalp hair, a comparable volume of body hair can be collected. When mentioning head hair, we specifically mean scalp hair. Body hair encompasses all other hair varieties (such as facial and underarm hair).

Process Overview

The primary stages in the lab’s drug test processing include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a sample into a lab’s workflow. This step involves confirming that the sample was appropriately sealed and delivered, generating a unique LAN (Laboratory Accessioning Number), and completing any missing data entry not already added by an electronic tracking system.

Screening is a preliminary evaluation for substance abuse. Though Screening is a cost-efficient method to dismiss drug consumption for most samples, a positive outcome requires confirmation for courtroom validity. Any samples that test positive during Screening must undergo further confirmation.

If a sample turns out presumptively positive during Screening, additional hair is collected from the original sample for Extraction. In this phase, drug traces are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluids), which makes hair drug testing among the most challenging procedures to execute.

Positive Screening results are confirmed via GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, presumptive positive samples are cleansed as necessary. The comprehensive laboratory workflow from Accessioning to Confirmation is examined under the CAP (College of American Pathologists) Hair certification and complies with ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments detect substance use up to 90 days, unlike urine tests with a shorter timeframe.
• Resilience to deception: Hair drug assessments are hard to manipulate, thus ensuring more precise results.
• Historical insights: Offers a historical view of drug consumption patterns over time, not just recent activity.

Limitations:

• Inability to detect recent use: Drugs become evident in hair around 5-7 days post-consumption.
• Expense: Hair drug evaluations tend to be pricier than alternative testing options.
• Result disparities: Variables like hair color and individual differences in hair growth can influence metabolite concentration in hair.

Note: Commonly termed "hair follicle tests", the evaluation analyzes the hair strand, not the follicle beneath the scalp.
