Hair Follicle Drug Testing - Waltreak, AR

What it is, How it works

The utilization of hair analysis has emerged as an effective means for detecting drug and alcohol consumption. Hair captures a long-term record of substances by ensnaring biomarkers within the fibers of the growing hair strand. When cut near the scalp, it offers an approximate 3-month detection period for alcohol and drugs. Hair collection is straightforward, relatively hard to tamper with, and easy to transport.

Collecting a 1.5-inch lock of roughly 200 hair strands (approximately the thickness of a #2 pencil) nearest to the scalp results in 100mg of hair, which is the ideal quantity for diagnosis and validation. For EtG, additional analyses, and/or tests exceeding 10 panels, 150mg of the sample is advised. It's suggested to weigh the hair using a jeweler’s scale. In the absence of scalp hair, a comparable quantity of body hair may be gathered. References to head hair signify scalp hair solely. Body hair encompasses other hair types (facial, axillary, etc.).

Process Overview

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

Accessioning involves the preliminary entry of a sample into a lab’s framework. This encompasses confirming that the sample was correctly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data input not furnished by an electronic chain of custody framework.

Screening involves a swift initial assessment for drugs of abuse. Although Screening is an economical means to dismiss drug usage in most samples, a positive screen must be confirmed to be viable in court. Any samples that are presumptively positive in Screening necessitate a secondary confirmation.

When a sample is presumptively positive in the Screening phase, further hair is extracted from the initial sample and readied for Extraction. During this stage, drugs are extracted from hair at a considerably lower density than in other methods (e.g., urine or oral fluid), making hair drug screening a challenging methodology.

Validation of any positive screening result is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation as required. The comprehensive lab procedure from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests can identify drug use for up to 90 days, in comparison to urine tests which have a more limited detection period.
• Difficulty in deception: It is highly challenging to deceive a hair drug test, thus enhancing result accuracy.
• Offers historical data: It can exhibit a pattern of drug use over a timeframe, not merely recent usage.

Limitations:

• Inability to identify recent use: It requires roughly 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests tend to be pricier than other drug testing approaches.
• Result variability: Elements such as hair color and individual differences in hair growth can influence the concentration of drug metabolites in the hair.

Note: While often named "hair follicle tests", the analysis itself evaluates 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.
