Hair Follicle Drug Testing - Prentice, WI

What it is, How it works

Hair testing has emerged as a potent method for the identification of drug and alcohol consumption. Hair retains a long-term record of alcohol and other drugs by embedding biomarkers within the fibers of the extending hair strand. When sourced near the scalp, hair can offer up to a roughly 3-month timeframe for detecting alcohol and other drugs. Hair is straightforward to collect, comparatively tough to adulterate, and convenient to send.

A 1.5-inch segment of about 200 hair strands (comparable to the dimension of a #2 pencil) nearest to the scalp will yield 100mg of hair, the preferred sample size for evaluation and verification. For EtG, add-on tests, and/or evaluations beyond 10 panels, a recommendation of 150mg of the specimen is made. It is advised to weigh the specimen with a jeweler's scale. If scalp hair is unobtainable, an equivalent quantity of body hair may be gathered. By head hair, we imply only scalp hair. Body hair relates to all other hair categories (facial, axillary, etc.).

Process Overview

The four critical steps involved in the laboratory processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial processing of a specimen into a lab's system. This process includes ensuring that the sample was appropriately sealed and delivered, assigning a random LAN (Laboratory Accessioning Number), and completing any supplemental data entry not furnished by an electronic chain of custody system.

Screening entails an initial swift evaluation for drugs of abuse. Although Screening is an economical approach to exclude drug usage on the majority of specimens, a positive screen must be verified to be admissible in court. Any specimens that are seemingly positive in Screening do require a follow-up confirmation.

If a specimen is seemingly positive in the Screening phase, more hair is extracted from the initial sample and readied for Extraction. In this phase, drugs are extracted from hair at a substantially lower concentration than in other methodologies (ex. urine or oral fluid), which is why hair drug screening is the most challenging methodology to perform.

Confirmation of any positive screening outcome is carried out via GC/MS, GC/MS/MS or LC/MS/MS. All seemingly positive specimens are cleansed before confirmation as required. The entire laboratory process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use for up to 90 days, as opposed to urine tests which have a narrower detection window.
• High difficulty to deceive: It is exceedingly challenging to deceive a hair drug test, ensuring the accuracy of results.
• Offers historical data: It can provide a pattern of drug usage over a span of time, not merely recent usage.

Limitations:

• Inability to detect recent usage: It requires around 5-7 days for drugs to be visible in hair.
• Expense: Hair drug tests are typically more costly compared to other drug testing methods.
• Result variations: Factors such as hair color and individual variances in hair growth can influence the concentration of drug metabolites in the hair.

Note: Although often referred to as "hair follicle tests", the test itself examines the hair strand and not 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.
