Hair Follicle Drug Testing - Federal Hill, MD

What it is, How it works

Hair analysis is now recognized as an effective means for identifying drug and alcohol consumption. Hair retains a prolonged record of alcohol and drug use by capturing biomarkers in the strands as they grow. When sampled near the scalp, hair offers a detection window of roughly three months for substances like alcohol and drugs. The collection is easy, quite resistant to tampering, and straightforward to transport.

A sample measuring 1.5 inches consisting of approximately 200 hair strands (comparable to a #2 pencil size) nearest to the scalp provides 100mg, which is the optimal sample amount for screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, a specimen weight of 150mg is advised. Use a jeweler’s scale to weigh the specimen accurately. In situations where scalp hair is absent, a comparable volume of body hair can be collected. Head hair is specifically referring to scalp hair, whereas body hair includes other types (facial, axillary, etc.).

Process Overview

The core steps in the lab processing of drug test results include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the step where a sample is initially managed in the laboratory system. Essential tasks include ensuring the sample’s seal and shipment integrity, assigning a LAN (Laboratory Accessioning Number) randomly, and filling in any missing data not covered by an electronic chain of custody system.

Screening consists of an initial evaluation for substance abuse. Although Screening is a cost-efficient method to exclude drug use in a majority of samples, confirmed results are necessary for court admissibility. Samples yielding a positive result in Screening require further confirmation.

When a sample yields a positive result in Screening, extra hair is extracted from the original specimen and set aside for Extraction. Here, drugs are isolated from the hair at concentrations lower than in other techniques (e.g., urine or saliva), highlighting hair drug screening as one of the most complex methodologies available.

Confirmations of positive results are carried out using GC/MS, GC/MS/MS, or LC/MS/MS technology. All samples presumed positive undergo washing prior to confirmation when necessary. The entire laboratory workflow from Accessioning to Confirmation is reviewed in accordance with both CAP (College of American Pathologists) Hair specifications and ISO / IEC 17025 accreditation standards.

Benefits of hair drug testing:

• Long detection span: Hair drug tests can identify drug use up to 90 days, whereas urine tests have a much shorter detection period.
• Hard to manipulate: It is notably challenging to deceive a hair drug test, enhancing result reliability.
• Tracks drug history: It identifies drug consumption patterns over extensive periods rather than just recent usage.

Drawbacks:

• Limited recent detection: Drugs require about 5-7 days to be noticeable in hair.
• Expense: Hair drug tests tend to be pricier compared to other testing approaches.
• Result variability: Elements like hair color and individual variations in growth can impact metabolite concentrations found in hair.

Note: The test often called as “hair follicle test” actually examines the hair strand and 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.
