Hair Follicle Drug Testing - Saint Gabriel, LA

What it is, How it works

Hair analysis is recognized as an effective method for identifying drug and alcohol consumption. The hair serves as a long-term record of alcohol and other drug use by encapsulating biomarkers within the strands as they grow. When taken from near the scalp, hair can offer up to a roughly three-month window for detecting alcohol and other drugs. Hair is straightforward to collect, relatively hard to tamper with, and simple to send.

A 1.5-inch segment encompassing around 200 hair strands (approximately the thickness of a #2 pencil) nearest to the scalp will yield 100mg of hair, the optimal quantity for screening and confirmation processes. For EtG, additional tests, and tests exceeding 10 panels, 150mg of the sample is advised. We suggest utilizing a jeweler’s scale to weigh the specimen. In the absence of scalp hair, an equivalent amount of body hair can be used. When mentioning head hair, we specifically refer to scalp hair. Body hair denotes all other hair categories (facial, armpit, etc.).

Process Overview

The core procedures involved in the lab processing of a drug test result encompass Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a sample into a laboratory’s system. This step involves confirming that the sample was intact and shipped correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data not supplied by an electronic chain of custody system.

Screening involves a preliminary rapid test for abused drugs. Although Screening provides a cost-effective method to dismiss drug usage for most samples, any positive result must be confirmed to be legally valid. Any samples presumed positive during Screening necessitate a subsequent confirmation.

If a sample is presumed positive at the Screening stage, more hair is extracted from the initial sample and prepared for Extraction. In this step, drugs are retrieved from hair at a significantly lower concentration than in other methods (e.g., urine or oral fluid), highlighting why hair drug analysis is the most challenging method to perform.

Confirmation of any positive Screening result is achieved using GC/MS, GC/MS/MS, or LC/MS/MS methodologies. All samples presumed positive are cleansed before confirmation as required. The comprehensive lab process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug evaluations can identify drug use for up to 90 days, unlike urine tests that have a shorter detection timeframe.
• High resistance to tampering: It is exceedingly difficult to deceive a hair drug test, ensuring more precise results.
• Historical usage insight: It can reveal a pattern of drug consumption over time, not just recent usage.

Limitations:

• Cannot identify recent usage: It requires roughly 5-7 days for drugs to appear in hair.
• Expense: Hair drug evaluations are generally costlier than other testing methods.
• Result variability: Elements like hair color and individual hair growth discrepancies can influence the level of drug metabolites in hair.

Note: Although frequently called "hair follicle tests", the examination itself evaluates 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.
