Hair Follicle Drug Testing - Ravenswood, LA

What it is, How it works

Hair analysis has emerged as a robust method for identifying drug and alcohol consumption. Hair offers an extensive timeline of substance use by capturing biomarkers within its growing fibers. When gathered near the scalp, it delivers up to a 3-month detection range for alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and simple to transport.

A 1.5-inch segment of approximately 200 hair strands (roughly the diameter of a #2 pencil) near the scalp provides 100mg of hair, which is optimal for screening and confirmation. For EtG, additional tests, or panels exceeding 10, a 150mg sample is suggested. It is advised to utilize a jeweler’s scale for precise measurement. Should scalp hair be inaccessible, a comparable quantity of body hair can be used. "Head hair" refers specifically to scalp hair, while "body hair" denotes all other hair types (e.g., facial, axillary).

Process Overview

The four primary stages in laboratory processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning consists of the sample's entry into the lab's system. This step ensures the sample’s proper sealing and shipment, assigns a random Laboratory Accessioning Number (LAN), and finalizes any additional data not included by an electronic custody chain.

Screening conducts an initial, rapid assessment for drug abuse. Although Screening is cost-efficient for excluding drug use in most cases, any positive indications must be verified to be legally valid. Any sample that tests positive in Screening requires secondary confirmation.

Should a sample test positive during Screening, additional hair is extracted from the main sample and prepped for Extraction. During Extraction, drugs are removed from hair at much lower levels than in other methods (like urine or saliva), making hair analysis notably complex to execute.

Confirmation of positive results is performed using GC/MS, GC/MS/MS, or LC/MS/MS technologies. All samples presumed positive are cleaned before confirmation if necessary. The whole lab procedure from Accessioning to Confirmation is evaluated under both the College of American Pathologists (CAP) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair analysis detects drug use up to 90 days, whereas urine tests cover a shorter span.
• Difficult to evade: Cheating a hair drug test proves very challenging, increasing accuracy.
• Tracks historical drug use: It reveals a pattern over time, unlike tests focusing on recent usage.

Limitations:

• Unable to detect recent drug use: Drugs become detectable in hair after roughly 5-7 days.
• Expense: Hair tests generally cost more than other testing methods.
• Result Variability: Factors like hair color and personal hair growth differences can influence drug metabolite levels in hair.

Note: Although commonly called "hair follicle tests", the analysis examines the hair strand itself, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

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.
