Hair Follicle Drug Testing - Carthage, MO

What it is, How it works

The practice of analyzing hair has emerged as a significant method for detecting substance use. Hair serves as a long-time record of alcohol and drug activity, encapsulating indicators within the threads of the hair as it grows. Obtaining hair near the scalp can reveal consumption patterns of alcohol and drugs for up to three months. The process of collecting hair is straightforward, relatively immune to tampering, and convenient for transportation.

An ideal test sample consists of a 1.5-inch section of approximately 200 hair strands (about the girth of a #2 pencil) nearest to the scalp, yielding 100mg of hair suited for analysis and verification. For EtG screenings, additional tests, or tests exceeding ten panels, a specimen of 150mg is suggested. Using a jeweler's scale to weigh the sample is advisable. In the absence of scalp hair, a similar volume of body hair can be used. The term "head hair" specifically denotes scalp hair, while "body hair" refers to all other hair types (facial, axillary, etc.).

Process Overview

The laboratory evaluation of a drug test result involves four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial entry of a sample into a lab’s workflow. It involves checking that the sample remains sealed and was transported correctly, allotting a unique LAN (Laboratory Accessioning Number), and handling any additional informational input absent from a digital chain of custody system.

Screening serves as an initial rapid assessment for substance misuse. While Screening is a budget-friendly approach to initially exclude drug use for most inputs, a positive result necessitates validation for legal suitability. Any sample provisionally testing positive during Screening must undergo additional verification.

For samples that are provisionally positive at the Screening phase, supplementary hair is taken from the original sample to prepare for Extraction. During this stage, substances are isolated from hair at notably lower concentrations than in methods like urine or mouth fluid, which explains the complexity of executing hair drug assessments.

Verification of positive screen findings is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Before verification, all samples presumed positive are washed as required. The complete lab process from Accessioning to Confirmation is evaluated in alignment with both the CAP (College of American Pathologists) Hair designation and the accreditation following ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug evaluations can spot substance use up to 90 days, unlike urine tests which offer a shorter detection span.
• Challenge to deceive: Evasion of a hair drug assessment is highly challenging, enhancing result precision.
• Furnishes past usage data: It illustrates a drug consumption pattern over a duration, not merely recent activity.

Limitations:

• Incapable of detecting recent usage: Substances become detectable in hair only after approximately 5-7 days.
• Expense: Hair drug evaluations typically cost more than other drug screening techniques.
• Result variability: Variations such as hair pigmentation and individual differences in hair growth can influence the levels of drug metabolites in the hair.

Note: Commonly referred to as "hair follicle tests," this test analyzes the hair strand rather than the follicle beneath the scalp
