Hair Follicle Drug Testing - Russellville, AR

What it is, How it works

The utilization of hair testing has emerged as a significant method for identifying drug and alcohol usage. Hair retains a prolonged record of alcohol and drugs by capturing biomarkers within the strands of hair as they grow. When cut near the scalp, hair can yield a visibility period of approximately 3 months for substances like alcohol and drugs. It is easy to gather, less prone to tampering, and simple to mail.

A 1.5-inch sample consisting of about 200 hair strands (comparable to the width of a #2 pencil) taken nearest to the scalp provides 100mg of hair, the ideal quantity for both screening and verification. For tests including EtG, add-ons, and/or exceeding 10 panels, 150mg of the sample is advisable. Using a jeweler’s scale is recommended for measuring the sample. In the absence of scalp hair, an equivalent volume of body hair can be collected. When we mention head hair, it refers solely to scalp hair. Body hair encompasses all other hair categories (facial, axillary, etc.).

Process Overview

The procedure for laboratory analysis of a drug test result is categorized into four steps: Accessioning, Screening, Extraction, and Confirmation.

In the Accessioning phase, the sample is integrated into the laboratory’s system for initial processing. This step involves verifying the sample’s sealing and shipping integrity, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent in the electronic chain of custody system.

Screening is an initial brief assessment for identifying drug abuse. Though Screening offers a cost-effective way to exclude drug usage across most samples, a positive result must be verified to be considered valid in court. Samples with a presumptive positive in Screening require a secondary confirmation.

When Screening indicates a presumptive positive, additional hair is extracted from the initial sample for the Extraction stage. Here, drugs are extracted from hair at notably lower concentrations than other methods (such as urine or oral fluid), which contributes to hair drug testing being the most complex methodology to execute.

Positive screening outcomes are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleansed before confirmation when necessary. A comprehensive review of the entire lab process from Accessioning to Confirmation is conducted under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug usage for a duration of up to 90 days, unlike urine tests that offer a shorter detection span.
• High resistance to manipulation: Cheating on a hair drug test is extremely challenging, thus providing more precise outcomes.
• Historical usage pattern: It can show a pattern of drug consumption over time, beyond just recent usage.

Limitations:

• Inability to indicate recent substance use: It takes roughly 5-7 days for drugs to become traceable in hair.
• Expense: Generally, hair drug testing incurs higher costs than alternative drug testing methods.
• Variability in findings: Elements such as hair color and personal differences in hair growth may affect drug metabolite density within hair.

Note: Even though frequently called "hair follicle tests", the analysis is performed on the hair strand itself, not the follicle beneath the scalp.
