Hair Follicle Drug Testing - Emlenton, PA

What it is, How it works

Hair tests are recognized as a robust method for detecting drug and alcohol consumption. Hair retains a long-term record of substances by embedding biomarkers within the growing hair's fibers. When collected proximate to the scalp, hair can offer up to a three-month detection timeframe for drugs and alcohol. Collecting hair is straightforward, somewhat challenging to tamper with, and easy to transport.

A 1.5-inch segment of roughly 200 hair strands (similar in width to a #2 pencil) near the scalp provides 100mg of hair, the optimal sample for screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, 150mg of the hair specimen is advised. We suggest weighing the sample using a jeweler's scale. If scalp hair is not accessible, an equivalent quantity of body hair can be collected. When discussing head hair, we mean scalp hair exclusively. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The four fundamental steps in the laboratory processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning comprises the initial processing of a sample into a lab's system. This step includes verifying that the sample was sealed and shipped correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry absent from an electronic chain of custody system.

Screening provides an initial rapid check for drug use. Although Screening is a cost-efficient method to exclude drug usage in most samples, a positive result requires confirmation to be admissible in court. Samples that screen presumptively positive require a confirmatory analysis.

If Screening indicates a presumptive positive, additional hair is extracted from the initial sample and prepared for Extraction. In this phase, drugs are extracted from hair at a significantly lower concentration than other methods (e.g., urine or oral fluid), affirming why hair drug screening is highly complex to execute.

Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed before confirmation as necessary. The full laboratory process 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:

• Long detection window: Hair drug tests can detect drug use for up to 90 days, unlike urine tests that have a shorter detection period.
• Difficulty to cheat: Cheating a hair drug test is very challenging, enhancing result accuracy.
• Provides historical data: Hair drug tests can reveal a pattern of drug use over time, beyond recent usage.

Limitations:

• Cannot detect recent use: There is a lag of approximately 5-7 days before drugs become detectable in hair.
• Cost: Hair drug tests typically cost more than other drug testing techniques.
• Variations in results: Variables such as hair color and personal differences in hair growth can influence drug metabolite concentration in hair.

Note: Though often referred to as "hair follicle tests", this test 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.
