Hair Follicle Drug Testing - Antelope Hills, WY

What it is, How it works

Hair testing is increasingly recognized as an effective method for identifying drug and alcohol consumption. By embedding biomarkers in the fibers of the growing hair, hair offers a long-term record of substance use. Hair samples collected close to the scalp can provide a detection window of up to about three months for alcohol and drugs. The collection process for hair is straightforward, not easily tampered with, and simple to transport.

A 1.5-inch sample comprising around 200 strands (comparable to a #2 pencil in thickness) near the scalp yields 100mg of hair, which is optimal for both screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, a sample of 150mg is advised. Use a jeweler’s scale to weigh the specimen. If scalp hair is not available, the equivalent amount of body hair may be used. Head hair specifically refers to scalp hair, while body hair includes all other types of hair (such as facial and axillary).

Process Overview

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

Accessioning is the initial step of processing a sample within a lab’s system. It involves ensuring the sample was correctly sealed and shipped, allocating a random LAN (Laboratory Accessioning Number), and completing any data entry tasks that an electronic chain of custody system hasn’t covered.

Screening is a preliminary analysis for drugs of abuse. While it is a cost-efficient approach to exclude drug usage in the majority of cases, a positive screen requires confirmation for legal acceptability. Presumptively positive samples in Screening necessitate a secondary confirmation.

When a sample shows presumptive positivity in the Screening phase, additional hair is extracted from the initial sample and processed for Extraction. In this phase, drugs are extracted from hair at lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug testing the most complex methodology.

Confirmation of any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples are washed before confirmation, as necessary. The complete lab process, from Accessioning to Confirmation, adheres 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 tests can identify drug usage for up to 90 days, unlike urine tests, which have a shorter timeframe.
• Difficult to manipulate: It is extremely hard to tamper with a hair drug test, enhancing the accuracy of the results.
• Offers historical insight: It reveals patterns of drug use over an extended period, not just recent consumption.

Limitations:

• Cannot identify recent usage: Drugs take roughly 5-7 days to appear in hair.
• Expense: Hair drug tests tend to be costlier than other testing options.
• Result variability: Factors like hair color and personal growth differences can influence drug metabolite concentrations in the hair.

Note: The test analyzes the hair strand, often mislabeled as "hair follicle tests," 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.

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.
