Hair Follicle Drug Testing - Hannasville, PA

What it is, How it works

Hair examination is increasingly recognized as an effective method for identifying substance and alcohol consumption. Hair offers a prolonged timeline of alcohol and drug usage by retaining biomarkers in the fibers of the hair as it grows. When sourced from near the scalp, hair can present an alcohol and drug detection span of up to three months approximately. Hair is straightforward to collect, challenging to tamper with, and convenient to transport.

A segment of 1.5 inches consisting of nearly 200 hair strands (comparable to a #2 pencil's diameter) from the scalp area yields 100mg, which is the optimal sample size for evaluation and confirmation. For EtG, additional tests, and tests exceeding 10 panels, a 150mg sample is advisable. Utilizing a jeweler’s scale is suggested for weighing the sample. Should scalp hair be unavailable, an equivalent volume of body hair may be used. When discussing head hair, it solely pertains to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test outcome encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial stage where a sample is integrated into a laboratory’s system. This process includes ensuring that the sample was appropriately sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and performing any supplementary data entry absent from an electronic chain of custody system.

Screening serves as a preliminary rapid assessment for substance abuse. Although Screening is an economical means to reject drug use in most samples, any positive screen must be confirmed for court acceptance. Samples suggesting positive results in Screening necessitate further confirmation.

When a sample indicates a presumptive positive in Screening, additional hair is taken from the initial sample and readied for Extraction. In this stage, substances are drawn from hair at a concentration significantly lower than that in other testing methods (such as urine or oral fluid), leading to hair drug screening being the most challenging methodology to execute.

Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation as required. The comprehensive lab process from Accessioning to Confirmation undergoes review according to both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can identify drug use over up to 90 days, compared to urine tests, which have a shorter detection duration.
• Difficulty to cheat: Hair drug tests are very tough to cheat, resulting in more precise outcomes.
• Provides historical records: The test can reveal a pattern of substance use over time, not merely recent activity.

Limitations:

• Cannot detect recent use: It requires about 5-7 days for substances to become detectable in hair.
• Expense: Generally, hair drug tests are pricier than other testing methods.
• Variability in outcomes: Factors like hair color and individual hair growth differences can influence drug metabolite concentration in the hair.

Note: Though often termed "hair follicle tests," the analysis focuses on the hair strand rather than the hair 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.
