Hair Follicle Drug Testing - Avilla, AR

What it is, How it works

Hair analysis has come to be recognized as an influential instrument for identifying drug and alcohol consumption. Hair captures a long-term record of alcohol and drug exposure by embedding biomarkers within the fibers of the developing hair strand. When taken near the scalp, hair can deliver a detection timeframe of up to approximately three months for alcohol and drugs. The collection of hair is straightforward, relatively tamper-resistant, and simple to transport.

A 1.5-inch portion of around 200 hair strands (roughly the thickness of a #2 pencil) near the scalp provides 100mg of hair, which is the preferred sample size for screening and validation. For EtG, additional testing, and/or beyond 10-panel tests, 150mg of the sample is advised. It is suggested to weigh the sample using a jeweler’s scale. Should scalp hair be unavailable, an equivalent volume of body hair can be collected. In the context of head hair, we specifically mean scalp hair. Body hair encompasses all other hair categories (facial, axillary, etc.).

Procedure Summary

The primary procedures involved in processing a drug test result in the lab are Accessioning, Screening, Extraction, and Confirmation.

Accessioning comprises the initial handling of a sample as it enters the lab system. This process includes confirming that the sample was properly sealed and transported, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing any other data input not covered by an electronic chain of custody system.

Screening entails a preliminary rapid assessment for substance abuse. While Screening offers a cost-efficient method to eliminate drug usage from most samples, a positive screen must be verified to hold up in legal proceedings. Any samples with presumptive positives during Screening require further confirmation.

If a sample tests presumptively positive at the Screening phase, additional hair is extracted from the initial sample and readied for Extraction. In this step, drugs are isolated from hair at significantly lower concentrations than in other techniques (e.g., urine or oral fluid), which makes hair drug screening the most challenging methodology to execute.

Verification of any positive screening results is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleansed before confirmation as necessary. The complete lab procedure from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection duration: Hair drug assessments identify drug use for up to 90 days, unlike urine tests which have a shorter detection timeframe.
• Difficult to counterfeit: It is quite challenging to deceive a hair drug test, thus enhancing the accuracy of results.
• Delivers historical insights: It supplies a pattern of drug use over a timeframe, beyond just immediate use.

Limitations:

• Incapable of detecting recent use: It requires approximately 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug assessments generally incur more costs than other testing methods.
• Result variability: Elements such as hair color and personal variations in hair growth can influence the concentration of drug metabolites in the hair.

Note: Though often termed as "hair follicle tests", the analysis is conducted on the hair strand and 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.
