Hair Follicle Drug Testing - Vanderbilt, PA

What it is, How it works

Hair analysis has emerged as a significant resource for identifying drug and alcohol consumption. Providing a comprehensive history of alcohol and drug biomarkers, hair entraps them within the fibers of the developing hair strand. When hair is collected near the scalp, it can offer up to a 3-month detection period for alcohol and drugs. Hair is easy to gather, hard to tamper with, and straightforward to transport.

Collecting a 1.5-inch section of approximately 200 hair strands (equivalent to a #2 pencil's thickness) near the scalp yields 100mg, an optimal amount for both screening and confirmation. For EtG, add-ons, and tests surpassing 10 panels, 150mg is advisable. Utilizing a jeweler’s scale is recommended for measuring the specimen. In the absence of scalp hair, a comparable quantity of body hair is acceptable. References to head hair denote only scalp hair, while body hair encompasses all other hair types (such as facial and axillary).

Process Overview

In the lab processing of a drug test result, the four pivotal steps include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary integration of a sample into the lab system. Steps include verifying proper sample sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not covered by an electronic chain of custody system.

Screening executes an initial, expedited evaluation for drug abuse. Though economically efficient for ruling out most drug use cases, any positive screening must be verified for court admissibility. Samples yielding a presumptively positive outcome in Screening necessitate a follow-up confirmation.

Should a sample be presumptively positive in Screening, further hair is drawn from the initial sample for Extraction. This phase isolates drugs from hair at lower concentrations than alternative methods (such as urine or oral fluid), underscoring the complex nature of hair drug analysis.

Subsequent Confirmation of any positive screening outcome employs GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo pre-confirmation washing if necessary. The comprehensive lab process from Accessioning to Confirmation undergoes scrutiny based on the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug use up to 90 days, unlike urine tests with shorter detection spans.
• Hard to manipulate: Hair drug tests are arduous to deceive, enhancing result accuracy.
• Reveals historical patterns: It charts drug use patterns over time, rather than pinpointing merely recent usage.

Limitations:

• Inability to detect recent usage: Drugs become noticeable in hair after approximately 5-7 days.
• Expense: Hair drug tests generally incur higher costs than alternative drug testing methods.
• Result variability: Hair color and personal growth differences can impact drug metabolite concentrations in hair.

Note: Although commonly known as "hair follicle tests", the analysis actually 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.
