Hair Follicle Drug Testing - Chatfield, MN

What it is, How it works

Hair analysis has become recognized as an effective means for identifying alcohol and drug consumption. Hair records a comprehensive timeline of alcohol and drug intake by capturing biomarkers within the strands of hair as they grow. When hair is clipped near the scalp, it can offer a retrospective window of up to roughly 90 days for alcohol and drugs. Hair is straightforward to obtain, relatively tamper-resistant, and convenient for transport.

A hair sample of 1.5 inches consisting of approximately 200 strands (comparable to the girth of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal quantity for initial tests and verification. For EtG, supplementary tests, or analyses exceeding 10 panels, a sample of 150mg is advisable. It is suggested that the sample be weighed using a jeweler’s scale. If scalp hair is not accessible, an equivalent quantity of body hair can be used. When addressing head hair, it specifically refers to scalp hair. Body hair encompasses all other hair types (such as facial, axillary, etc.).

Process Overview

The key stages in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the preliminary workflow of integrating a sample into a laboratory’s records. This step includes ensuring that the sample is correctly sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional entries absent from an electronic custody system.

Screening performs a preliminary assessment for substance abuse. While Screening is a cost-effective method to exclude drug use for most samples, a confirmed positive result is necessary for legal proceedings. Any samples flagged as potentially positive during Screening require a further confirmation test.

Should a sample be potentially positive at the Screening phase, additional hair is utilized from the initial sample to prepare for Extraction. This step isolates drugs from hair at much lower concentrations compared to other methods such as urine or saliva, which is why hair drug screening is considered the most challenging procedure.

Confirmation of any positive Screening result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that indicate a presumptive positive are cleansed before confirmation as needed. The complete lab process, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair certification and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, as opposed to urine tests which have shorter detection timelines.
• Resistance to manipulation: Cheating a hair drug test is very challenging, resulting in more reliable outcomes.
• Historical insight: It enables the mapping of drug use patterns over time, rather than just recent consumption.

Limitations:

• Inability to detect recent consumption: It takes roughly 5-7 days for drugs to be traceable in hair.
• Expense: Hair drug tests generally incur higher costs compared to other drug testing techniques.
• Result discrepancies: Variables such as hair color and individual differences in hair growth may influence the concentration of drug residues in hair.

Note: Although often termed "hair follicle tests", the analysis targets the hair strand, not the follicle beneath the skin.

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.
