Hair Follicle Drug Testing - Marianne, PA

What it is, How it works

Hair testing has emerged as an effective means for identifying drug and alcohol consumption. Hair serves as a record keeper of alcohol and other substances by locking biomarkers within its strands as it grows. When taken near the scalp, hair can indicate usage for up to around three months. The collection process is straightforward, manipulation is quite challenging, and shipment is uncomplicated.

A 1.5-inch sample composed of roughly 200 hair strands (around the thickness of a #2 pencil) nearest to the scalp provides 100mg of hair for optimal screening and verification. For EtG, additional analyses, and/or testing beyond 10 panels, a 150mg specimen is advisable. It’s suggested to measure the specimen using a jeweler's scale. If scalp hair is missing, a comparable amount of body hair may be acquired. When discussing head hair, it pertains solely to scalp hair. Body hair includes all other hair types (e.g., facial, axillary).

Process Overview

The drug testing cycle in a laboratory comprises four critical steps: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample is logged into the laboratory system. This phase ensures the sample’s proper sealing and dispatch, assigns a random LAN (Laboratory Accessioning Number), and completes any remaining data entry not managed by an electronic chain of custody.

Screening involves a preliminary quick analysis for drugs of abuse. Though Screening serves as a cost-effective method for excluding drug use in most samples, a positive screen must be validated for legal acceptability. Confirming presumptively positive samples from Screening is essential.

Upon a presumptive positive in the Screening phase, additional hair is taken from the initial sample for Extraction. In this phase, drug extraction from hair occurs at notably lower concentrations than via other methods (e.g., urine or oral fluids), hence making hair drug screening a challenging method.

Positive screening results undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS technologies. Presumptive positive samples are washed for confirmation when necessary. The laboratory process from Accessioning to Confirmation undergoes review adhering to both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Long-lasting detection: Hair drug tests can identify drug use for as long as 90 days, unlike urine tests which have shorter detection periods.
• Hard to manipulate: The difficulty in tampering with a hair drug test results in more accurate findings.
• Historical usage data: It showcases a blueprint of drug consumption over time, not merely recent use.

Limitations:

• Cannot detect immediate use: Drugs become detectable in hair after about 5-7 days.
• Expense: Hair drug tests generally cost more than alternative drug testing methods.
• Result variability: Elements like hair color and individual hair growth variations can influence the metabolite concentration in hair.

Note: Commonly called "hair follicle tests", this test evaluates the hair strand rather than the follicle situated 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. The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
