Hair Follicle Drug Testing - Concord, MA

What it is, How it works

The application of hair testing has emerged as a potent method for identifying the use of drugs and alcohol. Hair can encapsulate biomarkers within the growing fiber strands, offering a historical timeline of alcohol and other substances. When clipped close to the scalp, hair samples can offer approximately a 3-month window for detecting alcohol and drugs. Collection is straightforward, tampering is relatively challenging, and shipment is convenient.

Obtaining a 1.5-inch segment, approximately 200 hair strands (comparable to a #2 pencil's diameter) nearest to the scalp results in a 100mg sample, which is optimal for both screening and confirmation. For tests involving EtG, add-ons, or those exceeding 10 panels, a 150mg specimen is advisable. Utilizing a jeweler’s scale is recommended for weighting the specimen. If head hair is inaccessible, body hair of equal quantity may be used. References to head hair pertain solely to scalp hair, whereas body hair encompasses all other types (such as facial or axillary hair).

Process Overview

The laboratory processing of a drug test result entails four primary steps: Accessioning, Screening, Extraction, and Confirmation.

The Accessioning phase entails the preliminary integration of a sample into the lab's system. This phase includes the verification of proper sample sealing and shipment, the allocation of a random LAN (Laboratory Accessioning Number), and the completion of any supplemental data entry absent from electronic chain-of-custody systems.

The Screening phase involves an expedient preliminary evaluation for drugs of abuse. Screening serves as a cost-efficient means to negate drug usage for the bulk of samples. However, any positive screen must undergo Confirmation to ensure admissibility in a legal context. Samples returning presumptive positive results in Screening are subject to further Confirmation.

Samples found presumptively positive during Screening advance to the Extraction stage, where additional hair is extracted from the initial collection for preparation. In this stage, drugs are drawn from hair at markedly lower concentrations than other methods (e.g., urine or oral fluid), underscoring the complexity of hair drug testing.

Confirmation of any positive screening outcome occurs through GC/MS, GC/MS/MS, or LC/MS/MS techniques. Any samples identified as presumptive positive undergo cleansing prior to Confirmation, as warranted. The complete lab process—from Accessioning to Confirmation—is scrutinized per both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Capable of detecting substance use for up to 90 days, offering a more extended window than urine testing.
• Resistance to tampering: Hard to manipulate, thereby enhancing result reliability.
• Historical insight: Yields a timeline pattern of drug use, rather than solely recent instances.

Limitations:

• Recent usage detection incapability: Approximately 5-7 days are necessary before drugs become detectable within hair.
• Expense: Typically pricier than alternative drug testing techniques.
• Outcome variation: Factors such as hair pigmentation and growth rate differences can influence metabolite concentration observed within the hair.

Note: Commonly branded as "hair follicle tests," the technique analyzes the hair strand, not the subscalp follicle.

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.
