Hair Follicle Drug Testing - Epworth Heights, OH

What it is, How it works

Hair analysis is gaining recognition as a robust method for detecting drug and alcohol usage. Hair retains a longitudinal record of alcohol and other substances by capturing biomarkers within its fibers as it grows. When sourced near the scalp, hair can reveal up to a roughly 3-month detection timeframe for alcohol and other substances. Hair is straightforward to collect, challenging to adulterate, and straightforward to transport.

A 1.5-inch hair sample of about 200 strands (approximating the thickness of a #2 pencil) from nearest to the scalp provides 100mg of hair, which is the optimal sample for screening and verification. For EtG, add-ons, and/or tests exceeding 10 panels, a 150mg specimen is advisable. It's suggested to weigh the specimen using a jeweler’s scale. If scalp hair is not available, a comparable quantity of body hair may be collected. "Head hair" specifically denotes scalp hair only. "Body hair" encompasses all other hair types (incl. facial, axillary, etc.).

Process Overview

The process comprises four principal stages in the laboratory analysis of a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses processing a sample into a lab's system. This entails confirming the sample was sealed and transported correctly, assigning an arbitrary LAN (Laboratory Accessioning Number), and filling out any supplementary data entry absent from an electronic chain of custody system.

Screening entails an initial swift assessment for substances of abuse. Although Screening is a budget-friendly method to exclude drug use in most samples, a positive screen must be verified for judicial validity. Any samples that suggest positivity in Screening necessitate a secondary confirmation.

Should a sample seem positive during the Screening stage, additional hair is extracted from the original specimen and prepared for Extraction. Here, drugs are isolated from hair at a considerably lower concentration than in alternative methodologies (like urine or oral fluid), which contributes to the complexity of hair drug screening.

Confirmation of any positive screening outcome is performed with GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positivity undergo washing prior to confirmation as required. The comprehensive laboratory procedure from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timespan: Hair drug tests can identify drug usage for as long as 90 days, in contrast to urine tests, which have a briefer detection span.
• Cheat-proofing: It's quite challenging to manipulate a hair drug test, leading to more precise results.
• Offers historical data: It reveals a pattern of drug consumption over a duration, not merely recent use.

Limitations:

• Inability to detect recent usage: There's a lag of approximately 5-7 days before drugs become detectable in hair.
• Expense: Hair drug testing generally incurs higher costs than other drug testing techniques.
• Result variations: Elements like hair color and individual differences in hair growth can influence the concentration of drug metabolites within the hair.

Note: Commonly termed "hair follicle tests", the examination focuses on 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. 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.
