Hair Follicle Drug Testing - Emblem, WY

What it is, How it works

Hair analysis is regarded as a robust technique for uncovering the consumption of alcohol and drugs. The hair strands serve as a historical record, preserving biomarkers within the fibers over time. A sample obtained near the scalp can reveal drug and alcohol use with up to a 90-day detection window. Collecting hair is straightforward, resistant to tampering, and easy to transport.

Obtaining a 1.5-inch segment of approximately 200 hair strands (similar in size to a #2 pencil) from the scalp yields around 100mg of hair, which is optimal for screenings and confirmations. For tests involving EtG, add-ons, or more than 10 panels, a 150mg sample is advisable. It is recommended to measure the sample on a jeweler’s scale. If scalp hair is not available, an equal amount of body hair is suitable. Head hair specifically refers to scalp hair; body hair covers other types (facial, axillary, etc.).

Process Overview

Laboratory processing of drug test results includes four key phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial handling of a sample as it enters a laboratory system. This step ensures the sample is sealed and shipped accurately, assigns a unique LAN (Laboratory Accessioning Number), and completes any outstanding data entry not covered by an electronic chain of custody.

Screening offers a preliminary assessment for substance abuse. Though Screening is an economical method to dismiss drug use in most samples, a positive result must undergo confirmation to be admissible in court. Presumptively positive samples in Screening require subsequent confirmation.

Should a sample test positive during Screening, additional hair is sourced from the initial sample for Extraction. During Extraction, the drug is retrieved from hair at substantially lower concentrations compared to other tested substances (like urine or oral fluid), which explains why hair drug testing is the most complex method to implement.

Confirmation for any positive screening outcome is performed through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo a washing step before confirmation as necessary. The entire sequence from Accessioning to Confirmation complies with both the CAP (College of American Pathologists) Hair designation and accreditation according to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection period: Hair drug tests can trace drug use as far back as 90 days, unlike urine tests with shorter detection periods.
• Cheat-resistant: It is exceedingly challenging to deceive a hair drug test, thus ensuring accuracy of results.
• Chronic data: It reveals patterns of drug use over time, not just recent consumption.

Limitations:

• Incapable of recent detection: Drugs become detectable in hair after about 5-7 days.
• Expense: Generally, hair drug testing costs exceed those of other methods.
• Result variability: Variables like hair color and individual hair growth rates can impact drug metabolite concentrations in hair.

Note: Often termed "hair follicle tests", this test assesses the hair strand 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.
