Hair Follicle Drug Testing - Whatley, AL

What it is, How it works

Hair testing has emerged as an effective means for identifying drug and alcohol consumption. Hair can capture a detailed history of substance use by holding biomarkers within the growing hair strand's fibers. If collected near the scalp, hair can reveal usage within roughly a 3-month period. Collection is straightforward, tampering is challenging, and shipping is convenient.

A 1.5-inch sample, comprising roughly 200 hair strands (similar in size to a #2 pencil) near the scalp, provides 100mg of hair, suitable for both screening and confirmation. For EtG add-ons and/or tests exceeding 10 panels, 150mg of hair is advisable. We suggest using a jeweler's scale for accuracy. If scalp hair is unavailable, an equal quantity of body hair can be collected. "Head hair" indicates scalp hair exclusively, while "body hair" pertains to all other hair types (e.g., facial, axillary).

Process Overview

The laboratory processing of a drug test involves four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial stage of logging a sample into a laboratory's system, which includes ensuring the sample was properly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any outstanding data entry not covered by an electronic chain of custody system.

Screening involves a preliminary examination for drug abuse. While Screening is an economical approach to exclude drug use in most samples, a positive result necessitates confirmation for legal acceptance. Samples that test as presumptively positive in Screening require additional confirmation.

With a presumptive positive in the Screening stage, additional hair is extracted from the original sample and prepped for Extraction. Here, drugs are isolated from the hair at a notably lower concentration than in other methods, such as urine or oral fluid, which is why hair testing is a challenging method to conduct.

Confirmation of any positive screening result is performed using GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples undergo washing before confirmation if required. The complete laboratory process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extensive detection duration: Hair drug tests can identify drug use over a span of 90 days, unlike urine tests which have a briefer detection span.
• Hard to manipulate: Tampering with hair drug tests is quite difficult, resulting in more reliable outcomes.
• Offers historical data: This method can outline drug use patterns over time, not merely recent intake.

Limitations:

• Inability to identify recent usage: It generally takes about 5-7 days for drugs to become apparent in hair.
• Expense: Hair drug tests typically cost more than alternative drug testing methods.
• Result variability: Factors like hair color and individual hair growth differences can influence drug metabolite concentrations in hair.

Note: Although often termed as "hair follicle tests", it is the hair strand that is analyzed, 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. 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.
