Hair Follicle Drug Testing - Wallace, FL

What it is, How it works

Hair assessments are now recognized as an effective method for identifying drug and alcohol consumption. Hair serves as a timeline for alcohol and drug intake by embedding biomarkers within the fibers of the hair strand as it grows. When acquired near the scalp, hair can reveal up to a roughly 3-month timeframe for alcohol and drug detection. Hair is straightforward to collect, relatively tamper-resistant, and simple to transport.

A 1.5-inch section of roughly 200 hair strands (equivalent to the thickness of a #2 pencil) nearest the scalp provides 100mg of hair, which is the optimal sample size for analysis and validation. For EtG, supplementary tests, or panels exceeding 10, a specimen size of 150mg is suggested. It is advised to weigh the specimen using a jeweler’s scale. If scalp hair is lacking, a comparable amount of body hair can be obtained. The reference to head hair specifically means scalp hair. Body hair encompasses all other hair types (such as facial or axillary hair).

Process Overview

The lab processing of a drug test outcome encompasses four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial procedure of entering a sample into the lab’s system. This involves confirming the sample was properly sealed and dispatched, allocating a random LAN (Laboratory Accessioning Number), and finalizing any additional data entry absent from an electronic chain of custody system.

Screening constitutes an initial rapid assessment for substances of abuse. While Screening is an economical approach to eliminate drug use for most samples, a positive result necessitates validation to be valid in legal proceedings. Samples that test presumptively positive during Screening require further verification.

If a sample tests presumptively positive in Screening, additional hair is extracted from the original specimen and readied for Extraction. In this phase, substances are extracted from hair at substantially lower concentrations than in other methods (such as urine or oral fluid), highlighting the complexity of hair drug screening.

Confirmation of any positive screening result is executed via GC/MS, GC/MS/MS, or LC/MS/MS. Any samples testing positively are washed before confirmation as required. The entire lab process, from Accessioning to Confirmation, is meticulously reviewed according to the standards set by both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify substance use for up to 90 days, unlike urine tests which have a shorter detection period.
• Hard to falsify: Cheating on a hair drug test is very challenging, ensuring more reliable results.
• Provides usage history: It offers a pattern of substance use across a duration, not solely recent usage.

Limitations:

• Cannot detect immediate usage: Drugs become detectable in hair after about 5-7 days.
• Expense: Hair drug tests typically incur higher costs than alternative drug testing methods.
• Result variability: Factors such as hair color and personal differences in hair growth can influence the concentration of drug metabolites in hair.

Note: Although frequently termed "hair follicle tests", this test examines the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

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.
