Hair Follicle Drug Testing - Avis, PA

What it is, How it works

Hair testing is increasingly recognized as an effective method for identifying drug and alcohol usage. By capturing biomarkers within the hair strands, hair offers a prolonged history of substance use. If hair is cut near the scalp, it may present about a three-month detection window for alcohol and drugs. Collecting hair is straightforward, challenging to tamper with, and convenient for shipping.

A 1.5-inch section from roughly 200 hair strands (comparable to a #2 pencil's thickness) near the scalp will yield 100mg of hair, which is the optimal sample for evaluation and validation. For EtG, add-ons, or examinations exceeding 10 panels, a 150mg sample is advised. It is recommended to measure the specimen using a jeweler’s scale. If scalp hair is not accessible, a similar quantity of body hair may be utilized. The reference to head hair pertains solely to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The primary steps in the laboratory procedure for processing a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial handling of a sample in a laboratory's system. This step involves ensuring that the sample is secured and transported correctly, allocating a random LAN (Laboratory Accessioning Number), and fulfilling supplementary data entry tasks not covered by an electronic chain of custody system.

Screening performs an initial rapid assessment for substance abuse. Although Screening economically identifies drug usage for most samples, a positive result requires confirmation for legal admissibility. Samples yielding presumptive positive results in Screening necessitate secondary confirmation.

If a sample yields a presumptive positive result during Screening, additional hair is extracted from the original specimen and prepared for Extraction. Here, drugs are extracted from hair at considerably lower concentrations than in other methods (e.g., urine or oral fluid), underscoring the complexity of hair drug screening.

Any positive outcome from screening undergoes Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS technologies. All presumptive positive specimens are cleansed before confirmation if necessary. The whole laboratory cycle, from Accessioning to Confirmation, is assessed under the CAP (College of American Pathologists) Hair designation and complies with ISO / IEC 17025 accreditation standards.

Benefits of hair drug testing:

• Extended detection window: Hair drug tests can uncover drug consumption for up to 90 days, contrasting with urine tests that have a shorter window.
• Hard to manipulate: Manipulating a hair drug test is very challenging, enhancing result accuracy.
• Offers historical insight: It provides an overview of drug usage patterns over a period, unlike tests that detect only recent usage.

Drawbacks:

• Incapable of detecting recent usage: Drugs become detectable in hair approximately 5-7 days after consumption.
• Expense: Compared to other drug testing alternatives, hair drug tests tend to be costlier.
• Result variance: Particular aspects such as hair color and personal hair growth variations can influence the drug metabolite concentrations in hair.

Note: Despite being referred to as "hair follicle tests", the evaluation is conducted on 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.
