Hair Follicle Drug Testing - Kerman, CA

What it is, How it works

Hair analysis is increasingly recognized as a vital means to identify drug and alcohol consumption. Hair serves as a repository for alcohol and drug markers by embedding them within the growing hair strand, offering a long-term history of substance use. When collected near the scalp, hair can reflect a roughly 3-month timeframe for detecting alcohol and drug use. The collection process for hair is straightforward, difficult to tamper with, and simple to transport.

Acquiring a 1.5-inch segment of approximately 200 hair strands (akin to the size of a #2 pencil) from the scalp provides 100mg, serving as the optimal amount for testing and confirmation. For EtG, additional assessments, and/or panels exceeding 10, it is advisable to collect 150mg. We suggest determining the specimen's weight using a jeweler’s scale. If scalp hair is unavailable, a comparable amount from body hair may be used. The term head hair specifically refers to scalp hair only, whereas body hair includes hair from other regions (such as facial, axillary, etc.).

Process Overview

The laboratory process in drug test evaluation consists of four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning represents the initial stage of integrating a sample into a lab's workflow. This phase involves confirming proper sealing and shipping of the sample, assigning it a LAN (Laboratory Accessioning Number), and executing any data entries not captured by electronic custody systems.

Screening signifies a preliminary examination for drugs of abuse. Although Screening is an efficient way to eliminate chances of drug use in most samples, a positive outcome requires subsequent validation for legal acceptance. Samples showing presumed positive results during Screening necessitate a confirmatory analysis.

In instances of presumptive positive results during Screening, more hair is extracted from the primary specimen for further preparation in Extraction. Here, substances are isolated from hair at lower concentrations than alternative methods (e.g., urine or oral fluid), making hair drug screening a complex procedure.

Verifying any positive findings from Screening is achieved through GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptive positive samples are cleansed before confirmation if necessary. The complete lab procedure from Accessioning to Confirmation is assessed under CAP (College of American Pathologists) Hair designation guidelines along with ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments can trace drug usage up to 90 days, in contrast with urine tests that cover a shorter duration.
• Resistance to manipulation: Attempting to cheat a hair drug examination is notably challenging, thus ensuring more reliable results.
• Offers chronological use data: It reveals a drug usage trend over time rather than just recent consumption.

Limitations:

• Cannot determine recent consumption: It generally takes 5-7 days for substances to become detectable in hair.
• Expense: Hair drug evaluations typically incur higher costs compared to other testing techniques.
• Result variability: Factors such as hair pigmentation and individual hair growth diversity can influence metabolite concentrations in hair.

Note: While commonly termed "hair follicle tests", the actual analysis targets the hair strand rather than the subcutaneous 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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented.
