Hair Follicle Drug Testing - Mayodan, NC

What it is, How it works

Hair testing is increasingly recognized as an effective method for identifying drug and alcohol use. By capturing biomarkers within the fibers of the growing hair strand, hair provides a comprehensive overview of alcohol and other drug usage over time. When hair is collected near the scalp, it can offer a detection window that extends to about 3 months for alcohol and other drugs. Hair is straightforward to gather, relatively hard to tamper with, and convenient to ship.

A sample of 1.5 inches, consisting of roughly 200 hair strands (approximately the girth of a #2 pencil), closest to the scalp contributes 100mg of hair, ideal for both screening and confirming tests. For EtG, add-ons, and/or tests exceeding 10 panels, a 150mg specimen is preferable. Utilizing a jeweler’s scale to weigh the specimen is advised. Where scalp hair is absent, an equivalent amount of body hair can be collected. Head hair refers specifically to scalp hair. Other types of hair (facial, axillary, among others) are categorized as body hair.

Process Overview

The processing of a drug test result in the laboratory entails four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the preliminary processing of a sample upon its introduction into a laboratory system. This stage ensures the sample was properly sealed and shipped, allocates a random Laboratory Accessioning Number (LAN), and finalizes any supplementary data entry not covered by an electronic chain of custody system.

Screening conducts an initial rapid test for potential drugs of abuse. Though a cost-effective strategy to dismiss drug usage in most samples, any positive Screen results necessitate confirmation for court admissibility. Samples deemed presumptively positive require further confirmation.

When a sample shows a presumptive positive result during the Screening phase, additional hair goes through preparation for Extraction. Here, drugs are isolated from hair at a much lower concentration than those in other methods (such as urine or oral fluid), which is why hair drug screening is considered the most intricate method to execute.

Confirmation of any screening process yielding a positive result is performed through GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, samples that were previously deemed presumptive positive undergo necessary washing. The entirety of the laboratory process from Accessioning through to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the accreditation conforming to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests detect drug use within a span of up to 90 days, whereas urine tests possess a more limited detection period.
• Hard to deceive: It poses a substantial challenge to manipulate a hair drug test, ensuring greater result accuracy.
• Offers historical insights: It presents a record of drug consumption over a duration, rather than merely documenting recent usage.

Limitations:

• Inability to identify recent use: It takes between 5-7 days before drugs become traceable within the hair.
• Expense: Hair drug tests commonly incur higher costs compared to alternative drug testing methods.
• Result variability: Conditions such as hair color and individual hair growth differences might impact drug metabolite concentrations in hair.

Note: While frequently termed as "hair follicle tests", the examination targets 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.
