Hair Follicle Drug Testing - Fountain Lake, AR

What it is, How it works

Hair analysis has gained recognition as an effective means for detecting drug and alcohol consumption. Hair holds a comprehensive history of alcohol and drug use by encapsulating biomarkers within the strands’ fibers as hair grows. When taken from close to the scalp, hair samples can offer a detection timeframe of up to three months for alcohol and other substances. Hair collection is straightforward, less prone to tampering, and easily transported.

A hair sample measuring 1.5 inches with roughly 200 strands (matching the size of a #2 pencil) closest to the scalp provides 100mg of hair, which is the optimal amount for both screening and confirmation. For EtG, additional tests, and testing exceeding ten panels, a specimen size of 150mg is suggested. Using a jeweler’s scale for weighing the sample is advised. In the absence of scalp hair, a similar quantity of body hair may be used. When referencing head hair, it pertains only to scalp hair. Body hair encompasses all other hair types (e.g., facial, axillary, etc.).

Process Overview

The laboratory processing for drug testing comprises four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves integrating a sample into a lab's system through initial processing. This step checks that the sample was properly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and finalizes any required data entry absent from an electronic chain of custody system.

Screening entails a preliminary rapid assessment for drugs of abuse. Although Screening is a cost-efficient approach for ruling out drug use in most samples, a positive screening must be authenticated for it to hold up in legal settings. Samples yielding a presumptive positive in Screening necessitate further confirmation.

Should a sample test presumptively positive during Screening, additional hair is taken from the primary specimen and readied for Extraction. Here, drug compounds are isolated from hair at significantly lower thresholds than in methods such as urine or oral fluid testing, underlining the complexity of hair drug screening as a methodology.

Confirmation of any positive Screening outcome is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are subject to washing before confirmation as warranted. The comprehensive lab process from Accessioning to Confirmation undergoes review per both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection: Hair drug tests can reveal drug usage up to 90 days, unlike urine tests with limited detection periods.
• Difficult to deceive: Cheating a hair drug test is challenging, enhancing result credibility.
• Shows historical use: It reflects drug use patterns over time, beyond just recent use.

Limitations:

• Inability to detect recent intake: Drugs become detectable in hair approximately 5-7 days post-use.
• Expense: Hair drug testing tends to be pricier than other drug test options.
• Result variability: Factors like hair color and individual growth rates can influence drug metabolite levels in hair.

Note: Often termed "hair follicle tests", the test actually examines the hair strand, not 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.
