Hair Follicle Drug Testing - Scotlandville, LA

What it is, How it works

Hair examinations have gained recognition as an efficacious means for identifying alcohol and drug consumption. Hair captures a protracted timeline of alcohol and drug intake by encasing biomarkers within the shaft of the developing hair. When taken from the scalp, hair offers nearly a 3-month detection period for alcohol and other substances. Hair is straightforward to collect, relatively challenging to tamper with, and convenient to transport.

A snippet measuring 1.5 inches, comprising approximately 200 hairs (akin to the thickness of a #2 pencil) nearest to the scalp, yields 100mg of hair, the optimal quantity for screening and verification. For EtG, supplementary tests, and/or analyses exceeding 10 panels, 150mg of the sample is advised. We suggest using a jeweler’s scale to weigh the sample. Should scalp hair be unavailable, a comparable amount of body hair may be utilized. "Head hair" denotes exclusively scalp hair, whereas "body hair" encompasses all other varieties such as facial, axillary, etc.

Process Overview

The laboratory processing of a drug test culminates in four principal steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial sample processing into a lab’s system, which entails verifying correct sealing and shipment of the sample, allocating a random LAN (Laboratory Accessioning Number), and completing any additional entries missing from an electronic chain of custody.

Screening is a preliminary, rapid assessment for substances of abuse. While screening effectively rules out drug consumption for most samples, a positive screen necessitates confirmation to be legally acceptable. Samples that presumptively test positive in Screening require further validation.

Should a sample be presumptively positive in the Screening phase, extra hair is taken from the original sample for Extraction. During this phase, drugs are drawn from hair at a notably lower concentration than other techniques, such as urine or oral fluid, making hair drug screening a challenging procedure.

Confirmation of any presumptive positive screening outcome employs GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing prior to confirmation where applicable. The entire process from Accessioning to Confirmation adheres to the reviews of both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests identify drug use for up to 90 days, surpassing urine tests with shorter detection timelines.
• Hard to manipulate: Cheating on a hair drug test is exceptionally difficult, enhancing result reliability.
• Chronological data: Demonstrates a drug use pattern over time, beyond just recent consumption.

Limitations:

• Inability to detect immediate use: Drugs become detectable in hair after roughly 5-7 days.
• Expense: Hair drug tests incur higher costs than other testing methods.
• Result variability: Hair color and personal hair growth differences can impact drug metabolite concentrations in hair.

Note: Despite the term "hair follicle tests," the analysis targets the hair strand, 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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis.
