Hair Follicle Drug Testing - Egbert, WY

What it is, How it works

Hair analysis has emerged as an effective method for identifying substance use. Hair holds an extended history of alcohol and drug consumption by encasing biomarkers within the threads of the expanding hair shaft. If taken near the scalp, hair can reveal up to a three-month detection duration for alcohol and drugs. Hair collection is straightforward, moderately challenging to tamper with, and easy to distribute.

A 1.5-inch segment of about 200 hair strands (roughly the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, which is optimal for both screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, it is advised to gather 150mg of the sample. Measuring the sample with a jeweler's scale is recommended. If scalp hair is not accessible, an equivalent quantity of body hair can be used. References to head hair imply scalp hair exclusively. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The key phases in lab analysis of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves initial entry of a sample into a lab’s system. This encompasses verifying the sample's proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entries not provided by an electronic chain of custody system.

Screening involves a preliminary examination for illicit drugs. While Screening is a cost-efficient method to exclude drug use on most samples, a positive finding must be confirmed for legal admissibility. Any Screening samples that are presumptively positive require secondary confirmation.

If a specimen shows a presumptive positive during Screening, further hair is extracted from the original sample and prepared for Extraction. In this phase, drugs are extracted from hair at a significantly lower concentration than other methods (ex. urine or oral fluid), which contributes to the complexity of hair drug testing methodology.

Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS or LC/MS/MS. All samples with presumptive positives are cleaned prior to confirmation as necessary. The entire laboratory analysis from Accessioning to Confirmation is inspected under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Prolonged detection window: Hair drug assessments can identify drug consumption up to 90 days, contrasted with the shorter detection window of urine tests.
• Challenging to alter: Manipulating hair drug test results is very difficult, enhancing result accuracy.
• Yields historical data: It provides a timeline of drug use across an extended period, rather than just recent use.

Limitations:

• Unable to detect recent use: Drug traces only become detectable in hair after approximately 5-7 days.
• Expense: Hair drug testing typically incurs higher costs than other drug testing procedures.
• Result variability: Variations such as hair color and individual differences in hair growth can impact the drug metabolite concentration in hair.

Note: Although sometimes called "hair follicle tests", the analysis 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.
