Hair Follicle Drug Testing - Chase, LA

What it is, How it works

Hair analysis is increasingly recognized as a potent method for identifying drug and alcohol consumption. Hair accumulates a historical record of alcohol and drug use by capturing biomarkers in the hair's growing fibers. When collected near the scalp, hair can offer up to a roughly 3-month detection period for alcohol and other substances. It is straightforward to collect, challenging to tamper with, and convenient to send.

A 1.5-inch section of about 200 hair strands (approximately the width of a #2 pencil) nearest the scalp yields 100mg of hair, considered the optimal sample size for preliminary and confirmatory testing. For EtG, additional tests, or tests over 10 panels, a 150mg sample is advised. We suggest weighing the hair sample using a jeweler's scale. If scalp hair isn't available, a comparable amount of body hair can be obtained. Mention of head hair pertains solely to scalp hair, whereas body hair includes all other types (facial, armpit, etc.).

Process Overview

The principal steps in laboratory processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary entry of a sample into a lab's system. This step involves ensuring the sample's seal and shipping integrity, assigning it a random LAN (Laboratory Accessioning Number), and finalizing any further data input not covered by an electronic chain of custody system.

Screening represents an initial rapid assessment for substances of abuse. Although Screening is a budget-friendly method for excluding drug use in most samples, a positive screen must be verified to be legally defensible. Samples that are initially positive in Screening necessitate additional confirmation.

Should a sample test presumptively positive during Screening, additional hair is retrieved from the original sample and readied for Extraction. In this phase, drugs are isolated from hair at a notably lower concentration than other techniques (e.g., urine or oral fluid), which accounts for the complexity of hair drug screening.

Verification of any positive screening result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS methods. Every presumptive positive sample is cleansed before confirmation as required. The entire lab procedure from Accessioning to Confirmation undergoes scrutiny per the CAP (College of American Pathologists) Hair standards and accreditation under ISO/IEC 17025 guidelines.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can discover drug consumption for up to 90 days, in contrast to the brief detection period of urine tests.
• Resistance to deception: Cheating on a hair drug test is extremely challenging, augmenting the accuracy of the outcomes.
• Offers historical insights: It can reveal a pattern of drug consumption over time, rather than just recent instances.

Limitations:

• Inability to identify recent consumption: Drugs only become detectable in hair after about 5-7 days.
• Expense: Hair drug tests generally incur greater costs than other screening approaches.
• Result variability: Aspects such as hair pigmentation and individual hair growth differences can modulate drug metabolite concentrations in hair.

Note: Though often termed "hair follicle tests", the analysis examines the hair strand as opposed to the follicle beneath the scalp

What's New In Hair Follicle Drug Testing according to the Hair Drug Testing Experts

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.

The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.

It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis.
