Hair Follicle Drug Testing - Mcmanus, LA

What it is, How it works

Hair analysis is now recognized as an effective means for identifying drug and alcohol use. Hair captures a long-term record of alcohol and drugs, trapping biomarkers within the fibers of the hair as it grows. Collected near the scalp, it offers approximately a three-month window for tracking alcohol and drug use. Hair is easy to collect, not easily tampered with, and simple to send.

A 1.5-inch hair sample, roughly 200 strands (around the thickness of a #2 pencil) close to the scalp, equals 100mg of hair, the preferred quantity for screening and confirmation. For EtG, additional elements, and/or analyses beyond ten panels, a 150mg specimen is advocated. Measuring the sample on a jeweler’s scale is advised. If scalp hair isn't present, a similar body hair amount can be used. 'Head hair' refers to scalp hair only, while 'body hair' includes all other kinds (beard, underarm, etc.).

Process Overview

The lab processing of a drug test result encompasses four critical stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase where a sample is entered into a laboratory's system. This phase includes confirming the sample was properly sealed and delivered, allocating a random LAN (Laboratory Accessioning Number), and completing any additional data entry missed by an electronic custody system.

Screening is a preliminary examination for drugs of abuse. Although Screening is cost-effective in ruling out drug use in most samples, a positive screen must be verified for legal acceptance. Presumptively positive Screening samples require a secondary confirmation.

If a sample tests presumptively positive in Screening, additional hair is retrieved from the original sample for the Extraction step. In Extraction, drugs are separated from hair at much lower concentrations compared to other methods (e.g., urine or saliva), making hair drug analysis the most challenging to conduct.

Positive Screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo washing before confirmation when necessary. The comprehensive laboratory sequence from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair tests can trace drug use for up to 90 days, unlike urine tests with a shorter window.
• Hard to manipulate: Cheating a hair drug test is very challenging, leading to more precise outcomes.
• Historical usage data: It showcases drug use patterns over time rather than recent use alone.

Limitations:

• No recent usage detection: It takes about 5-7 days for drugs to appear in hair.
• Expense: Hair drug tests generally cost more than other testing methods.
• Result variations: Hair color and individual differences in hair growth can influence drug metabolite concentrations in hair.

Note: Although termed "hair follicle tests", the test analyzes the hair strand and 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.
