Hair Follicle Drug Testing - Letart Falls, OH

What it is, How it works

Hair testing has emerged as an effective method for identifying drug and alcohol consumption. Hair retains a long-term record of alcohol and drug use by capturing biomarkers within the fibers of the hair shaft. When taken near the scalp, hair can offer a detection window of up to about three months for alcohol and drugs. Hair collection is straightforward, relatively tamper-resistant, and easy to transport.

A 1.5-inch sample of approximately 200 hair strands (about the circumference of a #2 pencil) closest to the scalp will yield 100mg of hair, the optimal sample for screening and confirmation. For EtG, add-ons, and/or testing exceeding 10 panels, a 150mg sample is advised. We suggest weighing the specimen with a jeweler’s scale. If scalp hair is not available, an equivalent amount of body hair can be used. By head hair, we mean scalp hair only. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The four primary stages in the laboratory processing of a drug test are Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial integration of a sample into a laboratory’s system. This process includes verifying the sample’s proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not supplied by an electronic chain of custody system.

Screening is a preliminary quick scan for drugs of abuse. Although Screening is a cost-efficient method to exclude drug use for most samples, a positive result needs confirmation to be court-admissible. Samples that are presumptively positive during Screening require subsequent confirmation.

If Screening suggests a positive result, more hair is taken from the original specimen and prepared for Extraction. In this phase, drugs are extracted from hair at a lower concentration than other methods (e.g., urine or oral fluid), which is the reason hair drug screening is the most challenging methodology to conduct.

Confirmation of any presumptive positive result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation if necessary. The complete laboratory process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug usage for up to 90 days, unlike urine tests that have a shorter detection period.
• Challenging to tamper with: Hair drug tests are challenging to cheat, thus providing more reliable results.
• Offers historical usage patterns: It can reveal drug use tendencies over time, not only recent usage.

Limitations:

• Cannot detect recent use: Drugs take around 5-7 days to become detectable in hair.
• Expense: Hair drug tests generally cost more than other drug screening methods.
• Result variations: Hair color and individual hair growth differences can influence drug metabolite concentrations in hair.

Note: Although referred to as "hair follicle tests", the analysis is performed on 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.

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.
