Hair Follicle Drug Testing - Rexton, MI

What it is, How it works

Hair analysis is now recognized as an effective method for uncovering drug and alcohol consumption. Hair archives a comprehensive record of alcohol and drug intake by embedding biomarkers within the fibers of its growing strand. When clipped near the scalp, hair can offer a detection timeframe of up to roughly 3 months for alcohol and drugs. Collecting hair is straightforward, posing challenges to tampering, and facilitates easy transport.

A 1.5-inch segment comprising approximately 200 hair strands (analogous to the width of a #2 pencil) close to the scalp provides 100mg of hair, constituting the optimal sample for both screening and confirmation. For EtG, additional tests, or assays exceeding 10 panels, a specimen of 150mg is advisable. It is recommended to assess the weight of the sample using a jeweler’s scale. In cases where scalp hair is absent, a comparable quantity of body hair can be gathered. When defining head hair, it exclusively denotes scalp hair. Body hair includes all other hair categories (facial, axillary, etc.).

Process Overview

The procedure in the lab for processing a drug test outcome involves four key phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the sample's initial enrollment into a lab's system, verifying proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and performing any extra data input not handled by an electronic chain of custody system.

Screening conducts an initial rapid assessment for common drugs of abuse. While it provides a cost-effective strategy to eliminate drug usage in most samples, a positive result in Screening mandates confirmation before court admissibility. Samples identified as presumptively positive in Screening necessitate secondary validation.

Should a sample be presumptively positive during Screening, additional hair is extracted from the original sample and prepared for Extraction. In this phase, drugs are isolated from hair at concentrations significantly lower than in alternative methods (e.g., urine or oral fluid), contributing to the complexity of hair drug screening.

Confirmation, for any positive screening outcomes, employs GC/MS, GC/MS/MS, or LC/MS/MS methodologies. All samples presumed positive undergo necessary pre-confirmation washing. The end-to-end laboratory process—from Accessioning to Confirmation—is scrutinized under CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug consumption up to 90 days, unlike urine tests, which offer a shorter detection period.
• Reduced chances of cheating: Manipulating results in a hair drug test is notably challenging, enhancing result fidelity.
• Historical insights: It yields a temporal record of drug usage patterns, beyond mere recent consumption.

Limitations:

• Unable to detect recent usage: Drugs only become detectable in hair after approximately 5-7 days.
• Expense: Generally, hair drug tests incur higher costs than alternative drug testing approaches.
• Result variability: Considerations such as hair color and individual hair growth variability may influence drug metabolite concentrations in hair.

Note: Despite common usage, the term "hair follicle tests" inaccurately describes the method, as it evaluates the hair strand rather than the follicle beneath the scalp.
