Hair Follicle Drug Testing - Cape Charles, VA

What it is, How it works

The perception of hair testing has shifted towards regarding it as an effective means for identifying alcohol and drug consumption. Hair encapsulates a prolonged record of substance use by embedding biomarkers within its strands. Collected close to the scalp, it can show up to a 3-month history of alcohol and other drug presence. The collection process is straightforward, tampering is relatively challenging, and it facilitates easy transport.

By obtaining a sample of 1.5 inches comprising approximately 200 hair strands (roughly comparable to a #2 pencil's girth) closest to the scalp, you acquire 100mg of hair, which is the standard amount for testing and verification. For testing involving EtG, additional requests, or tests exceeding 10 panels, 150mg of the sample is advised. Using a jeweler’s scale for weighing is suggested. If scalp hair is not available, a similar quantity of body hair can be used. The term 'head hair' applies solely to scalp hair, while 'body hair' encompasses all other hair types (facial, axillary, etc.).

Process Overview

The core stages in processing a drug test outcome in the lab are Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary step where a sample is integrated into a lab's system. It involves checking that the sample is appropriately sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any extra data entry beyond what an electronic chain of custody offers.

Screening provides an initial rapid test for drug abuse presence. It serves as a cost-efficient method to mostly eliminate drug usage detection, but any positive screening needs affirmation for legal admissibility. Presumptive positives identified in Screening mandate follow-up confirmation.

In cases of presumptive positives within Screening, additional hair is extracted from the primary sample for Extraction. At this stage, drugs are extracted from hair at much lower levels than in alternatives such as urine or oral fluid, underscoring why hair drug screening is highly challenging.

Positive outcomes from screening are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples indicated as presumptive positives are washed before confirmation when necessary. The entire lab process from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair standard and is ISO/IEC 17025 accredited.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests detect drug usage over a span reaching 90 days, as opposed to the shorter detection periods of urine tests.
• Low susceptibility to deceit: Hair drug tests are notably difficult to evade or alter, thereby ensuring results integrity.
• Tracks historical usage: It furnishes a record of substance use across an extended timeline, not just recent activity.

Limitations:

• Incapable of detecting recent usage: Drugs become noticeable in hair around 5-7 days post-use.
• Expense: Hair drug testing typically incurs higher costs compared to other methods.
• Result variability: Elements like hair color and individual hair growth differences can impact drug metabolite concentrations in hair.

Note: Although frequently termed as "hair follicle tests," the analysis actually targets the hair strand rather than 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.
