Hair Follicle Drug Testing - Berlin, MD

What it is, How it works

Hair analysis is increasingly recognized for its effectiveness in detecting substance and alcohol consumption. Hair strands encapsulate alcohol and drug biomarkers within their fibers, reflecting long-term usage history. When hair is sourced from near the scalp, it can offer an extended detection window, up to roughly three months, for substances and alcohol. Collecting hair is straightforward, tough to tamper with, and convenient for shipping.

Gathering a sample of around 1.5 inches, consisting of about 200 hair strands (similar in thickness to a #2 pencil), near the scalp will yield 100mg of hair, which is optimal for screening and validation. For EtG, additional tests, and/or analyses beyond 10 panels, a 150mg specimen is suggested. It is advisable to use a jeweler's scale to weigh the sample. Should scalp hair be absent, a similar quantity of body hair can be utilized. Reference to head hair pertains exclusively to scalp hair. In contrast, body hair encompasses all other types (facial, axillary, etc.).

Process Overview

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

Accessioning entails integrating a sample into the laboratory's system. This process verifies proper sealing and shipping, assigns a random Laboratory Accessioning Number (LAN), and completes any required data entry not covered via an electronic chain of custody.

Screening provides an initial assessment for possible drug use. Though Screening is an economical method for eliminating drug usage in most samples, any positive findings must be validated for legal acceptance. Presumptive positive results in Screening necessitate further confirmation.

If Screening yields a presumptive positive, an additional portion of the initial hair sample is utilized for Extraction. During this phase, drugs are isolated from hair at significantly lower concentrations compared to other tests (e.g., urine or saliva), highlighting the complexity of hair drug screening.

Confirmation of positive results from Screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positives undergo washing before confirmation when deemed necessary. The complete laboratory process, from Accessioning through Confirmation, is conducted under the oversight of both the College of American Pathologists (CAP) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests can indicate drug use for up to 90 days, unlike urine tests which have a shorter detection timeframe.
• Hard to manipulate: Tampering with hair drug tests is remarkably challenging, ensuring higher accuracy.
• Pattern data: It provides insights into drug use patterns over time, as opposed to merely recent usage.

Limitations:

• Limited to past use only: Detection in hair takes about 5-7 days post-drug consumption.
• Expense: Hair drug testing tends to be costlier than other testing approaches.
• Result variability: Factors such as hair color and individual hair growth rates can influence drug metabolite concentration.

Note: Although commonly called "hair follicle tests," the analysis focuses on the hair strands rather than 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.
