Hair Follicle Drug Testing - Gate, OK

What it is, How it works

Hair analysis is now regarded as an effective means for identifying drug and alcohol consumption. Hair captures a long-term record of substances by embedding biomarkers within the keratin structures of hair in development. Collected near the scalp, hair can reveal alcohol and drug use up to a roughly 3-month timeframe. It is straightforward to gather, challenging to tamper with, and convenient for transport.

An ideal sample comprises a 1.5-inch section of roughly 200 hair strands (comparable to a #2 pencil) closest to the scalp, providing 100mg for initial testing and verification. For EtG, additional parameters, and/or panels exceeding ten, 150mg is advisable. The specimen's weight should be verified via a jeweler’s scale. In the absence of scalp hair, an equivalent mass of body hair is a suitable alternative. Head hair exclusively refers to scalp hair; whereas, body hair encompasses all other types (e.g., facial, axillary).

Process Overview

The laboratory examination for drug testing comprises four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a sample into the lab's workflow, confirming proper sealing and transport, generating a unique LAN (Laboratory Accessioning Number), and addressing any necessary data entries not covered by an electronic custody chain.

Screening provides a rapid preliminary assessment for substance abuse. Although cost-efficient for excluding drugs in most samples, any positive findings in Screening necessitate a confirmatory test for legal admissibility. Samples with a provisional positive outcome at the Screening stage require follow-up validation.

Presumptive positives trigger further hair extraction from the original sample for the Extraction phase. During this stage, drugs are isolated from hair at concentrations significantly lower than those found in other techniques (such as urine or oral fluid), underscoring the complexity of hair drug testing.

Positive Screening results proceed to Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. Prior to Confirmation, any presumptive positive samples undergo necessary purification washes. The complete lab process, from start to finish, adheres to both CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection range: Hair drug assessments can trace substance use up to 90 days, unlike urine tests with shorter detection periods.
• Resistance to tampering: Hair drug screenings are exceptionally challenging to manipulate, enhancing result reliability.
• Reflects historical usage: It offers insights into long-term drug use patterns, not just recent activities.

Limitations:

• Inability to detect recent intake: Drugs typically need 5-7 days to become discernible in hair.
• Expense: Hair drug assessments tend to cost more than alternative testing methods.
• Result variability: Variables like hair color and personal hair growth differences can influence drug metabolite levels in hair.

Note: Commonly known as "hair follicle tests", the examination targets the hair shaft, not 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. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.
