Hair Follicle Drug Testing - Crestwood, KY

What it is, How it works

The use of hair testing has emerged as an effective technique for identifying drug and alcohol consumption. Hair serves as a record of alcohol and drug use over time by capturing biomarkers within the hair shaft as it grows. When hair is collected close to the scalp, it offers a detection period of around three months for various substances. The collection process is straightforward, tampering is not easy, and transportation is convenient.

A sample roughly 1.5 inches long consisting of about 200 hair strands (comparable in size to a #2 pencil) near the scalp yields 100mg of hair, the perfect quantity for both screening and verification. For comprehensive tests such as EtG or tests exceeding 10 panels, a larger sample of 150mg is advised. Utilizing a jeweler's scale to measure the specimen is recommended. Should scalp hair be unavailable, an equivalent measure of body hair is an alternative. The term head hair specifically refers to scalp hair, whereas body hair encompasses other hair types (facial, axillary, etc.).

Process Overview

The essential stages in lab processing of drug test data encompass Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial stage where the sample enters the lab system. This involves confirming that the sample was appropriately sealed and transported, allocating a random LAN (Laboratory Accessioning Number), and completing any extra data input not supplied by an electronic chain of custody system.

Screening is a preliminary rapid analysis for drugs of abuse. Although Screening is a budget-friendly method to negate drug use in most samples, a positive screening result needs further validation for court reliability. Presumptive positives in Screening mandate further confirmation.

Upon a presumptive positive in the Screening stage, additional hair is extracted from the preliminary sample and prepared for the Extraction phase. During Extraction, drugs are isolated from hair at a significantly lower concentration than other methodologies (such as urine or oral fluid), which makes hair drug testing the most complex methodology to execute.

Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples undergo washing before confirmation when required. The complete laboratory cycle from Accessioning to Confirmation is scrutinized under not only the CAP (College of American Pathologists) Hair classification but also the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests can identify drug consumption up to 90 days prior, unlike urine tests which have a more limited detection window.
• Resistance to tampering: It is exceptionally challenging to deceive a hair drug test, leading to more reliable results.
• Historical analysis: It supplies evidence of drug consumption patterns over a duration, not merely recent usage.

Limitations:

• Unable to identify recent intake: Drugs are typically detectable in hair after a period of 5-7 days.
• Cost implications: Generally, hair drug tests incur higher costs compared to alternative testing methods.
• Result variability: Variables like hair color and personal hair growth differences influence drug metabolite concentration in the hair.

Note: Despite being frequently termed "hair follicle tests", the analysis examines 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.

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.
