Hair Follicle Drug Testing - Mcmullin, VA

What it is, How it works

Hair tests are now regarded as a robust method for detecting the consumption of drugs and alcohol. Hair offers a lengthy history of alcohol and other substance use by holding onto biomarkers within the growing hair strand's fibers. When procured near the scalp, hair can provide an approximate 3-month timeframe for detecting alcohol and drug usage. Hair collection is straightforward, hard to tamper with, and simple to send.

A sample measuring 1.5 inches, containing around 200 hair strands (similar to the diameter of a #2 pencil) nearest to the scalp will provide 100mg of hair, which is the optimal sample size for both screening and confirmation. For EtG, further analyses, and/or tests exceeding 10 panels, it is advised to have a 150mg specimen. Using a jeweler’s scale is recommended for measuring the specimen. If scalp hair isn't available, a corresponding amount of body hair can be gathered. Head hair refers solely to scalp hair, whereas body hair pertains to all other types (such as facial or axillary hair).

Process Overview

The four primary steps in the lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step of integrating a sample into the lab's system. It involves checking that the sample was sealed and shipped correctly, assigning a random LAN (Laboratory Accessioning Number), and filling in any additional data entry missing from an electronic chain of custody system.

Screening is a preliminary rapid assessment for substance abuse. Although Screening offers a cost-efficient means to dismiss drug use in most samples, a positive screen requires confirmation to hold up in court. Any samples indicating presumptive positive outcomes in Screening necessitate a subsequent confirmation.

Should a sample show presumptive positivity during Screening, additional hair is taken from the original specimen and prepared for Extraction. Here, drugs are separated from hair at a significantly lower concentration than other methods (such as urine or oral fluid), making hair drug screening the most intricate to conduct.

Confirmation of any positive Screening result is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed before confirmation, if necessary. The full lab procedure from Accessioning to Confirmation undergoes review under the CAP (College of American Pathologists) Hair designation as well as the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair analysis can uncover drug use for up to 90 days, unlike urine tests with a shorter detection frame.
• High resistance to tampering: Hair drug tests are challenging to manipulate, ensuring more reliable results.
• Historical usage data: These tests can reveal a drug-use pattern over time, instead of just recent use.

Limitations:

• Inability to detect recent consumption: It takes around 5-7 days for drugs to become detectable in hair.
• Expense: Hair-based drug evaluations are typically costlier than alternative drug-testing techniques.
• Result disparities: Factors like hair color and individual variations in hair growth can influence drug metabolite levels in hair.

Note: Although often called "hair follicle tests", the evaluation focuses on the hair strand itself 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.
