Hair Follicle Drug Testing - Reading, MA

What it is, How it works

Employed particularly for uncovering drug and alcohol consumption, hair analysis stands out as a significant resource. Over time, hair entraps biomarkers within its fibers, offering an extended timeline of substance use by capturing alcohol and other drugs. When hair is trimmed very near to the scalp, it can reveal substance history over a period of roughly three months. Hair collection is straightforward, resists tampering with some difficulty, and can be transported with ease.

Gathering a 1.5-inch segment comprising around 200 hair strands (approximately matching a #2 pencil) nearest the scalp results in about 100mg of hair, the optimal amount for examination and validation. For extensive screenings involving EtG, add-ons, and/or analyses exceeding 10 panels, about 150mg of the sample is advised. Utilizing a jeweler’s scale for weighing the sample is recommended. Should scalp hair be unavailable, an equivalent quantity of body hair can serve as an alternative. Head hair strictly implies scalp hair, while body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

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

Accessioning marks the initial phase of integrating a sample into a lab’s system. This phase verifies the proper sealing and shipment of the sample, assigns a random LAN (Laboratory Accessioning Number), and addresses any further data input omissions from an electronic chain of custody system.

Screening is a preliminary swift evaluation for substance abuse. Screening serves as a cost-effective means to eliminate drug use suspicions for the majority of samples; nonetheless, any positive screen requires affirmation to be valid legally. Samples indicating presumptive positives during Screening necessitate additional confirmation.

In scenarios where a sample shows presumptive positivity within the Screening phase, supplementary hair is drawn from the originally collected specimen and readied for Extraction. Here, the concentration of drugs extracted from hair is significantly lower than that from other sources (such as urine or oral fluid), underscoring the complexity of hair drug analysis execution.

Positive findings from the screening process are validated using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives undergo washing in preparation for confirmation, if needed. The complete laboratory process, starting from Accessioning to Confirmation, is conducted adhering to both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can reveal drug consumption for up to 90 days, unlike urine testing which offers a more limited detection span.
• Challenging to falsify results: Hair drug tests pose significant difficulty for manipulation, enhancing accuracy and reliability.
• Chronicles usage data: It can chart a pattern of substance use over time, extending beyond immediate consumption details.

Limitations:

• Inability to ascertain recent use: Detectability of drugs in hair initially requires a period of about 5-7 days.
• Expense: Generally, hair drug testing incurs higher costs compared to other testing alternatives.
• Result variability: Influences like hair pigmentation and individual hair growth variations can impact the presence of drug metabolites within the hair.

Note: Though often termed as "hair follicle tests," the procedure focuses on analyzing the hair strand and does not involve the scalp-embedded hair 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.
