Hair Follicle Drug Testing - Elim, PA

What it is, How it works

Hair analysis is recognized as an efficient method for detecting drug and alcohol consumption. Hair strands store a long-term record of alcohol and drug ingestion by capturing biomarkers within their fibers. When obtained near the scalp, hair can deliver a detection window of up to around three months for alcohol and drugs. The collection process is straightforward, making it hard to tamper with and easy to courier.

A hair sample of 1.5 inches in length comprising approximately 200 strands (about the size of a #2 pencil) nearest to the scalp provides 100mg of hair, which is the optimal sample for both screening and confirmation. For EtG, supplementary analyses, or tests exceeding 10 panels, 150mg of the sample is advisable. Using a jeweler’s scale for weighing the specimen is recommended. Should scalp hair be inaccessible, an equivalent quantity of body hair can be collected. By scalp hair, we mean hair from the head, while body hair encompasses all other hair varieties (facial, axillary, etc.).

Process Overview

A drug test result's laboratory processing comprises four main stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial handling of a sample within a laboratory’s system, ensuring the sample's seals and shipment are intact, generating a random LAN (Laboratory Accessioning Number), and completing any further data entry absent in an electronic chain of custody system.

Screening serves as a preliminary rapid assessment for potential drug abuse. Although cost-effective in excluding drug use in most samples, a positive screen mandates confirmation to ensure court admissibility. Samples that presumptively result positive in Screening necessitate subsequent confirmation.

For presumed positive samples during the Screening phase, additional hair is extracted from the initial specimen for the Extraction stage. Here, drugs are retrieved from hair at significantly lower concentrations than other methods (such as urine or oral fluid), making hair drug screening the most challenging methodology to perform.

Confirmation of any positive screen outcomes is completed using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation as needed, all presumptive positive samples undergo washing. The full lab process from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can identify drug use for up to 90 days, which is longer than the detection window for urine tests.
• Difficulty to cheat: The accuracy of hair drug tests is heightened owing to the difficulty in cheating them.
• Provides historical data: It offers insights into patterns of drug use over time rather than just recent usage.

Limitations:

• Cannot detect recent use: Drugs require approximately 5-7 days before becoming detectable in hair.
• Cost: Hair drug tests tend to be more costly than other drug testing methods.
• Variations in results: Drug metabolite concentrations in hair can be influenced by hair color and individual hair growth variations.

Note: Despite often being called "hair follicle tests", the analysis actually examines the hair strand rather than the scalp’s hair follicle.

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.
