Hair Follicle Drug Testing - Eutaw, AL

What it is, How it works

Hair testing is recognized as an effective method for uncovering drug and alcohol consumption. The growing hair strand captures biomarkers, providing a long-term record of substance use. When collected near the scalp, hair can offer a detection window for up to nearly three months for alcohol and other substances. Hair is easy to obtain, challenging to tamper with, and simple to mail.

A sample measuring 1.5 inches that comprises around 200 hair strands (comparable to the size of a #2 pencil) near the scalp will yield 100mg of hair, the optimal sample size for screening and confirmation. For EtG, add-ons, and/or tests exceeding ten panels, 150mg of the sample is advised. We suggest using a jeweler’s scale to weigh the specimen. If scalp hair is not available, an equivalent quantity of body hair can be collected. References to head hair pertain solely to scalp hair. Body hair encompasses all other hair forms (facial, axillary, etc.).

Process Overview

The primary steps in the laboratory processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial integration of a sample into a lab's system. This step verifies the sample was properly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data entry absent from an electronic chain of custody.

Screening is an initial swift check for substances of abuse. Although Screening is a cost-efficient approach to exclude drug use on most samples, a positive screen demands confirmation for court admissibility. Any samples that yield a presumptive positive in Screening require a secondary verification.

Should a sample be presumptively positive in the Screening phase, additional hair is extracted from the original specimen and prepped for Extraction. At this juncture, drugs are extracted from hair at concentrations much lower than in other methods (e.g., urine or oral fluids), making hair drug screening the most challenging methodology to conduct.

Confirmation for any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumptively positive are cleaned prior to confirmation if needed. The entire laboratory process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, whereas urine tests have a shorter detection period.
• Hard to deceive: Manipulating a hair drug test is extremely difficult, enhancing result accuracy.
• Provides historical insights: It can reveal a pattern of drug use over time, not merely recent usage.

Limitations:

• Inability to detect recent use: It takes approximately 5-7 days for drugs to appear in hair.
• Expense: Hair drug tests are typically more costly than other testing methods.
• Result variation: Factors such as hair color and individual differences in hair growth may influence drug metabolite concentration in hair.

Note: Although commonly called "hair follicle tests", the actual test examines the hair strand, 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.

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.
