Hair Follicle Drug Testing - Frostburg, MD

What it is, How it works

The utilization of hair testing has gained recognition as an effective method for identifying drug and alcohol usage. Hair offers a prolonged history of substance exposure by encapsulating biomarkers within the fibers of the hair as it grows. When collected near the scalp, it can reveal substance exposure up to an estimated 3 months for alcohol and other drugs. Hair collection is straightforward, relatively tamper-resistant, and convenient to transport.

A 1.5-inch hair segment, comprising approximately 200 strands (similar to the thickness of a #2 pencil) near the scalp, yields 100mg of hair, which is the ideal quantity for screening and confirmation. For tests involving EtG, add-ons, or beyond 10 panels, a 150mg sample is advised. Using a jeweler’s scale for weighing the specimen is recommended. In instances where scalp hair is insufficient, an equivalent amount of body hair can be collected. References to head hair pertain exclusively to scalp hair, while body hair encompasses all other types (e.g., facial, axillary).

Process Overview

The laboratory processing of a drug test result comprises four main stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves integrating a sample into the laboratory system. This step ensures that the sample was properly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and completes any additional required data entry not covered by an electronic chain of custody system.

Screening consists of a preliminary assessment for substances of abuse. Though cost-effective for eliminating drug usage in most samples, a positive screen must be confirmed for legal admissibility. Samples with presumptive positive outcomes in Screening require further confirmation.

In cases where a sample indicates a presumptive positive during Screening, more hair is extracted from the initial sample for the Extraction stage. At this stage, substances are extracted from hair at lower concentrations than in other methods (such as urine or oral fluid), rendering hair drug screening the most challenging method to execute.

Confirmation of any positive screening result is accomplished via GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples undergo washing before confirmation where necessary. The comprehensive laboratory process, spanning Accessioning to Confirmation, is evaluated under the CAP (College of American Pathologists) Hair standards and accredited to ISO / IEC 17025.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, whereas urine tests have a more limited detection period.
• Resistance to tampering: The difficulty in altering hair drug tests enhances result accuracy.
• Chronological data provision: Hair testing can delineate drug use patterns over time, beyond just recent use.

Limitations:

• lacks recent use detection: Drugs take about 5-7 days to be evident in hair.
• Expense: Hair drug tests typically incur higher costs than alternate testing methods.
• Result variability: Elements like hair color and personal hair growth variations can influence drug metabolite concentrations in hair.

Note: Often termed as "hair follicle tests", the test in reality analyzes 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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis. The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
