Hair Follicle Drug Testing - Prairieville, LA

What it is, How it works

The utilization of hair testing has emerged as an effective means for detecting drug and alcohol consumption. Hair strands capture biomarkers in their growing fibers, offering a prolonged history of substance use. When collected near the scalp, hair can show results for alcohol and drugs dating back up to three months. The collection process for hair is straightforward, it's relatively resistant to tampering, and easy to transport.

A 1.5-inch segment comprising around 200 hair strands (similar in size to a #2 pencil) gathered from the scalp yields about 100mg, which is deemed an optimal amount for both screening and confirmation. For tests such as EtG, additional assays, or those exceeding 10 panels, 150mg of the specimen is advisable. We suggest measuring the sample using a jeweler’s scale. If scalp hair is unavailable, a comparable quantity of body hair might be used. References to head hair mean strictly scalp hair, whereas body hair encompasses all other types (including facial and axillary hair).

Process Overview

The lab processing of drug tests entails four major stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial stage in incorporating a sample into the laboratory’s framework. This process involves confirming the sample was properly sealed and sent, allocating a random LAN (Laboratory Accessioning Number), and inputting additional data missing from an electronic chain of custody setup.

Screening presents an initial rapid examination for prohibited substances. While it serves as an economical approach to dismiss drug usage in most samples, a positive screening result requires confirmation for court usage. Any samples projecting positive findings at the Screening stage necessitate a follow-up confirmation.

Samples indicating positive at the Screening phase undergo further hair extraction from the original sample for Extraction purposes. During Extraction, the drugs are obtained from hair at a much lower concentration than other techniques (e.g., urine or oral fluid); thus hair drug testing stands as one of the more challenging methodologies.

Positive screening results undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. All samples initially positive undergo washing if necessary before confirmation. The complete laboratory procedure from Accessioning to Confirmation undergoes review following both the CAP (College of American Pathologists) Hair guidelines and accreditation according to ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can uncover drug use up to 90 days in the past, unlike urine tests which have shorter time frames.
• Hard to falsify: Cheating a hair drug test is highly improbable, ensuring more reliable results.
• Presents past usage information: It offers a timeline of substance use, rather than just recent activity.

Limitations:

• Inability to determine recent consumption: Drugs take about 5-7 days to be traceable in hair.
• Higher expense: Hair testing typically involves higher costs than other drug assessment methods.
• Result variability: Elements like hair color and personal hair growth variations can influence the drug metabolite levels in hair.

Note: Despite the nomenclature "hair follicle tests," the procedure evaluates hair strands instead of 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.
