Hair Follicle Drug Testing - Dewalt, TX

What it is, How it works

Hair tests are now recognized as an effective means for detecting drug and alcohol consumption. Hair strands retain biomarkers in their fibers, offering a historical profile of alcohol and drug use. When gathered near the scalp, hair can reveal a drug and alcohol use record spanning up to three months. Collection is straightforward, tampering is difficult, and shipment is uncomplicated.

A 1.5-inch section containing around 200 hair strands (similar in size to a #2 pencil) taken close to the scalp yields 100mg of hair, an ideal quantity for both screening and confirmation. For tests like EtG, add-ons, or those exceeding 10 panels, a 150mg sample is advised. We suggest using a jeweler’s scale for accuracy in weighing the sample. If scalp hair is not available, a comparable amount of body hair is acceptable. When we mention head hair, we mean exclusively scalp hair. Body hair encompasses all other types (such as facial, axillary, etc.).

Process Overview

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

During Accessioning, a sample is initially integrated into the lab's system. This step ensures the sample was correctly sealed and shipped, assigns a unique LAN (Laboratory Accessioning Number), and completes any additional data entries absent from an electronic chain of custody system.

Screening offers a preliminary rapid assessment for substance abuse. While Screening is a cost-efficient method to eliminate drug use in most samples, a positive result requires confirmation before being considered valid in legal contexts. Samples that test presumptively positive in Screening necessitate a secondary confirmation.

If Screening results are presumptively positive, additional hair is extracted from the initial sample for the Extraction phase. At this stage, drugs are extracted from hair in significantly lower concentrations compared to other methods (e.g., urine or oral fluid), which contributes to the complexity of performing hair drug tests.

Positive Screening results undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples are washed as necessary. The entire process, from Accessioning to Confirmation, adheres to both CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests can identify drug usage for up to 90 days, unlike urine tests which monitor a more recent timeframe.
• Cheating is unlikely: Cheating on a hair drug test is very difficult, ensuring more reliable results.
• Chronological usage data: Provides an overview of drug use patterns over time, not only recent consumption.

Limitations:

• Recent use undetected: It takes about 5-7 days for drugs to appear in hair.
• Expense: Hair drug tests generally cost more than other methods.
• Result variability: Elements like hair color and individual hair growth rates can influence the metabolite levels in hair.

Note: Though termed "hair follicle tests," the analysis is conducted on 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.
