Hair Follicle Drug Testing - Correo, NM

What it is, How it works

The analysis of hair has become recognized as a robust method for identifying alcohol and drug usage. Hair encapsulates long-term substance clues by embedding biomarkers within the fibers of an expanding hair strand. When gathered near the scalp, hair can reveal up to about a 3-month window of substance detection. Hair is easy to gather, relatively tough to tamper with, and straightforward to send.

An ideal specimen for analysis involves a 1.5-inch portion consisting of roughly 200 hair strands (comparable to a #2 pencil), nearest to the scalp, amounting to 100mg. For EtG, add-ons, and/or examinations exceeding 10 panels, a larger sample of 150mg is advised. Using a jeweler’s scale to weigh the specimen is recommended. If head hair is unavailable, a similar volume of body hair can be used. The term "head hair" strictly refers to scalp hair, while "body hair" encompasses all other types (facial, axillary, etc.).

Process Overview

The drug test result analysis process involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the step where a sample is introduced into the lab’s system. This process includes confirming the proper sealing and shipping of the sample, assigning it a random LAN (Laboratory Accessioning Number), and completing any lacking data entry not captured by an electronic chain of custody system.

The screening phase provides a preliminary scan for substances of abuse. While an economically efficient way to discount drug use in most samples, a positive Screening outcome must be verified for legal proceedings. Samples with presumptive positive results in Screening are subject to further confirmation.

Should a sample indicate potential positivity during Screening, additional hair from the original specimen is set aside for Extraction. During this stage, drug components are extracted from hair at significantly lower concentrations compared to other approaches (e.g., urine or oral fluids), making hair the most challenging testing medium.

Confirmation of any positive screening outcome utilizes methods like GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation when needed. The complete laboratory process, from Accessioning to Confirmation, is scrutinized according to both the CAP (College of American Pathologists) Hair guidelines and the accreditation under ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can uncover drug use for up to 90 days, unlike urine tests, which reveal a shorter detection span.
• Resilience against tampering: The difficulty in circumventing a hair drug test results in greater accuracy.
• Trend data availability: It can illustrate patterns of drug usage over time, not merely recent usage.

Limitations:

• Incapacity for immediate detection: It takes about 5-7 days for drugs to become evident in hair.
• Expense: Hair drug tests generally incur higher costs than other testing forms.
• Result variability: Aspects like hair color and individual hair growth rates can influence drug metabolite concentration in hair.

Note: Commonly referred to as "hair follicle tests", the assessment targets the hair strand rather than the hair follicle located under the scalp

Why Hair Follicle Testing Beats Urine Testing

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.
