What it is, How it works

Hair testing is recognized as a substantial method for identifying alcohol and drug consumption. Hair maintains a detailed history of substance use by integrating biomarkers within the hair fibers during growth. When hair is gathered near the scalp, it can reveal a detection timeframe of up to 3 months for alcohol and drugs. The collection process for hair is straightforward, tampering is relatively hard, and it is simple to transport.

A standard sample involves a 1.5-inch segment of around 200 hair strands (similar to the thickness of a #2 pencil) nearest to the scalp, yielding 100mg of hair, which is the optimum quantity for analysis and confirmation tests. For EtG, additional substances, and/or panels exceeding 10, a specimen weight of 150mg is advised. Use of a jeweler’s scale is suggested for measuring the specimen. Should scalp hair be unavailable, a corresponding amount of body hair is an acceptable alternative. When mentioning head hair, it specifically pertains to scalp hair. Body hair comprises all other types (facial, axillary, etc.).

Process Overview

There are four fundamental phases in processing a drug test outcome in the lab: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the sample's initial integration into a lab's system, ensuring it was properly sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and completing any missing data not available through an electronic custody chain system.

Screening performs a preliminary evaluation for substance abuse. Although cost-effective in dismissing drug use for most samples, a positive Screening needs verification for court viability. Presumptive positive samples in the Screening process necessitate further confirmation.

Should a sample demonstrate a presumptive positive result in Screening, additional hair is utilized for preparation in the Extraction phase. Here, substances are drawn from hair at significantly lower concentrations compared to other approaches (like urine or oral samples), distinguishing hair drug screening as particularly challenging.

Verification of any positive Screening results is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing prior to confirmation when required. The entire lab sequence from Accessioning to Confirmation is reviewed following the CAP (College of American Pathologists) Hair designation, with accreditation adhering to ISO / IEC 17025 standards.

Advantages of hair drug testing:

Extended detection period: Hair tests can identify drug usage for up to 90 days, whereas urine tests offer a shorter timeframe.
Resistance to manipulation: Cheating a hair drug test is highly challenging, hence results are more reliable.
Tracks historical data: It represents drug use patterns over time, rather than just recent consumption.

Limitations:

Cannot identify recent intake: It requires approximately 5-7 days for drugs to register in hair samples.
Expense: Generally, hair testing is costlier compared to other methods of drug testing.
Result variability: Hair color and individual growth differences can influence drug metabolite concentration in hair.

Note: Despite being termed "hair follicle tests", the assessment examines the hair strand, not the follicle beneath the scalp.
