Hair Follicle Drug Testing - Rockville, MD

What it is, How it works

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged timeline of drug and alcohol biomarkers in the fiber of the growing strand. When sampled near the scalp, it offers a roughly 3-month detection range for alcohol and drugs. Hair is easy to collect, challenging to tamper with, and simple to transport.

A 1.5-inch section of around 200 hair strands (roughly the diameter of a #2 pencil) closest to the scalp yields 100mg of hair, ideal for testing and verification. For EtG, supplementary tests, and/or those exceeding 10 panels, a 150mg sample is advisable. We suggest utilizing a jeweler’s scale for weighing. If scalp hair isn't available, a comparable amount of body hair can be used. By 'head hair', we mean scalp hair exclusively. 'Body hair' encompasses all other hair forms (facial, axillary, etc.).

Process Overview

The primary stages in laboratory drug test analysis are Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial processing of samples into a lab's database. This covers verifying sealed and correctly shipped samples, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry absent from an electronic chain of custody.

Screening provides a preliminary assessment for drug abuse. While Screening effectively rules out drug use for most samples, a positive result must be confirmed for legal admissibility. Any presumptive positives from Screening demand further confirmation.

If a sample is likely positive post-Screening, additional hair is extracted from the original for Extraction. This phase extracts drugs from hair at markedly lower concentrations than other methods (e.g., urine or oral fluid), making hair screening one of the most challenging processes to execute.

Verification of positive screening outcomes occurs via GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicating possible positives are washed before confirmation as necessary. The comprehensive lab process, from Accessioning to Confirmation, is reviewed under both the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair tests can determine drug usage for up to 90 days, while urine tests offer a more limited window.
• Resistance to tampering: Hair testing is challenging to manipulate, enhancing the reliability of results.
• Reveals usage patterns: It shows a chronic drug use pattern over time rather than just recent usage.

Limitations:

• Inability to detect recent intake: Drugs become detectable in hair within approximately 5-7 days.
• Expense: Hair drug testing tends to be pricier than other testing techniques.
• Variability in outcomes: Factors like hair color and individual hair growth differences may impact metabolite concentration in hair.

Note: Frequently referred to as "hair follicle tests", the procedure assesses the hair strand itself, 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.
