Hair Follicle Drug Testing - Ventress, LA

What it is, How it works

Hair testing has emerged as an effective means for identifying drug and alcohol usage. Hair stores a long-term record of alcohol and other drug use by capturing biomarkers within the fibers of the hair shaft as it grows. When obtained near the scalp, hair offers a detection period of up to around 3 months for alcohol and different drugs. Hair is straightforward to gather, relatively challenging to tamper with, and simple to transport.

A 1.5-inch segment consisting of roughly 200 hair strands (about the width of a #2 pencil) cut close to the scalp will yield 100mg of hair, which is considered an ideal sample size for screening and confirmation purposes. For EtG, additional tests, and/or tests exceeding 10 panels, a sample size of 150mg is suggested. It's advisable to weigh the specimen on a jeweler’s scale. In the event scalp hair is unavailable, an equivalent amount of body hair may be collected. When mentioning head hair, we specifically refer to scalp hair. Body hair pertains to other hair types (facial, axillary, etc.).

Process Overview

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

Accessioning includes the preliminary processing of a sample within a lab's system. This step involves verifying that the sample was adequately sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent from an electronic chain of custody system.

Screening entails an initial cursory assessment for drugs of abuse. Although Screening provides a cost-effective method to exclude drug usage in most samples, a positive Screening must be confirmed for legal admissibility. Any samples that are tentatively positive during Screening require further confirmation.

Should a sample be tentatively positive during the Screening phase, additional hair is gathered from the original specimen and prepared for Extraction. During this stage, the drug content is extracted from hair at a notably lower concentration than with alternative methods (e.g., urine or oral fluid), making hair drug screening particularly challenging to conduct.

Confirmation of any positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples tentatively positive are cleansed before confirmation as required. The end-to-end laboratory procedure from Accessioning to Confirmation is vetted 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 period: Allows detecting drug use up to 90 days, unlike urine tests which offer a more limited detection period.
• Hard to evade: Cheating on a hair drug test is extremely challenging, resulting in more reliable outcomes.
• Historical insight: Provides a record of drug usage patterns over time, beyond just recent use.

Limitations:

• Cannot spot recent use: It takes roughly 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests usually cost more than other drug testing techniques.
• Result variability: Factors including hair color and personal differences in hair growth can influence the concentration of drug metabolites found in hair.

Note: Although frequently termed as "hair follicle tests", the analysis itself targets the hair strand rather than the scalp's hair follicle.

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.
