Hair Follicle Drug Testing - Wink, TX

What it is, How it works

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair captures a timeline of alcohol and drugs by locking biomarkers within the fibers of the hair strand as it grows. When collected close to the scalp, hair can offer a detection period of up to 3 months for alcohol and drugs. Hair is easy to gather, hard to tamper with, and straightforward to ship.

An ideal sample for analysis and confirmation is a 1.5-inch segment of about 200 hair strands (around the diameter of a #2 pencil) nearest to the scalp, providing 100mg of hair. For EtG, add-ons, and/or tests exceeding 10 panels, it's advised to collect 150mg of the sample. It is recommended to use a jeweler’s scale for weighing the sample. If scalp hair is not available, a comparable amount of body hair can be collected. When mentioning head hair, we mean scalp hair specifically. Body hair includes all other hair kinds (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial stage where a sample is processed into a laboratory's system. This process includes checking that the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry that an electronic chain of custody system does not provide.

Screening is a preliminary and rapid examination for drugs of abuse. Although Screening is a cost-effective method to exclude drug usage in most cases, a positive screen must be verified through confirmation to be considered valid in legal settings. Samples that test presumptively positive during Screening need a secondary confirmation.

In the event of a sample testing presumptively positive during the Screening phase, additional hair is pulled from the initial sample and prepared for Extraction. During this phase, drugs are extracted from hair, albeit at a significantly lower concentration than other methodologies (e.g., urine or oral fluid), making hair drug screening the most challenging methodology to perform.

Confirmation of any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are washed before confirmation as needed. The complete laboratory process from Accessioning to Confirmation is scrutinized under both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can reveal drug use for up to 90 days, unlike urine tests which offer a shorter detection window.
• Challenging to cheat: Cheating a hair drug test is extremely difficult, ensuring more reliable results.
• Shows historical data: It can demonstrate a pattern of drug use over time, not just recent consumption.

Limitations:

• Unable to detect recent use: It generally takes 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests tend to be costlier than other drug testing techniques.
• Result variations: Elements such as hair color and personal differences in hair growth can influence the concentration of drug metabolites in hair.

Note: Though often called "hair follicle tests", the analysis is performed on the hair strand, not the hair 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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis.
