Hair Follicle Drug Testing - Thawville, IL

What it is, How it works

Hair testing has emerged as a significant method for detecting drug and alcohol consumption. Hair strands offer a long-range record of exposure to alcohol and other substances by capturing biomarkers in the strands' fibers. When collected near the scalp, hair can show a detection period of up to about three months for alcohol and other substances. The collection of hair is straightforward, relatively resistant to tampering, and easy to transport.

A sample measuring 1.5 inches, consisting of approximately 200 hair strands (roughly the diameter of a #2 pencil) nearest to the scalp provides 100mg of hair, which is ideal for screening and confirmation. For EtG, additional options, and/or tests exceeding 10 panels, a specimen weight of 150mg is advisable. Using a jeweler’s scale to weigh the sample is suggested. In the absence of scalp hair, an equal amount of body hair can be used. When referring to head hair, it exclusively relates to scalp hair. Body hair includes all other forms of hair (facial, axillary, etc.).

Process Overview

The primary stages in the laboratory processing of a drug test are Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the first step, involving the integration of a sample into the laboratory’s system. This step entails confirming the sample's proper sealing and shipment, assigning a unique LAN (Laboratory Accessioning Number), and completing any outstanding data entry not included in an electronic chain of custody system.

Screening is a preliminary swift assessment for drugs of abuse. Although Screening is an economical method to exclude drug use in the majority of cases, a screen indicating positivity must be validated for it to stand in legal proceedings. Samples testing presumptively positive during Screening require subsequent confirmation.

In the case of a presumptive positive result during Screening, additional hair is taken from the initial specimen for the Extraction phase. During this phase, the drugs are extracted from hair at a more diluted concentration than in other methodologies (e.g., urine or oral fluid), making hair drug screening the most challenging method to execute.

GC/MS, GC/MS/MS, or LC/MS/MS methods conduct the Confirmation of any positive screening outcomes. All samples indicating presumptive positivity undergo washing prior to confirmation when necessary. Each step of the laboratory process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and accreditation according 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, compared to the shorter detection period of urine tests.
• Minimal opportunity for deception: Cheating on a hair drug test is notably challenging, resulting in more reliable results.
• Records historical usage: It can reveal a trend of drug consumption over time, rather than solely recent use.

Limitations:

• Unable to detect recent use: Drugs generally become detectable in hair 5-7 days post-consumption.
• Expense: Typically, hair drug tests cost more than other drug testing techniques.
• Result variations: Factors including hair color and personal differences in hair growth can influence the drug metabolite concentration in the hair.

Note: While commonly called "hair follicle tests", the examination focuses 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.
