Hair Follicle Drug Testing - Stonega, VA

What it is, How it works

Hair testing is increasingly recognized as an effective method for identifying drug and alcohol use. Hair offers an extended history of substances by capturing biomarkers in its growing strands. When collected adjacent to the scalp, hair samples can offer up to a three-month detection span for drugs and alcohol. The process of collection is straightforward, hard to tamper with, and easy to transport.

A sample of 1.5 inches, consisting of about 200 hair strands (approximately the width of a #2 pencil) near the scalp, yields 100mg—an ideal sample size for both screening and confirmation. For EtG add-ons or tests exceeding 10 panels, a recommendation of 150mg is made. Using a jeweler’s scale is advisable for weighing the specimen accurately. Should scalp hair be unavailable, an equivalent quantity of body hair may be taken. When mentioning head hair, it pertains exclusively to scalp hair. Conversely, body hair encompasses all other types (like facial and axillary hair).

Process Overview

The laboratory processing of drug test results involves four core steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the first step, where a sample is incorporated into a lab's system. This ensures the sample is correctly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and completes data entry that isn’t included in an electronic chain of custody system.

Screening then takes place, offering an initial drug abuse check. While cost-effective to dismiss drug use in most samples, a positive screening requires confirmation for legal admissibility. Presumptive positives necessitate secondary confirmation.

Presumptive positives from Screening proceed to Extraction, where additional hair is taken from the specimen. In this phase, hair undergoes drug extraction at significantly lower concentrations than other methods (like urine or oral fluid), which renders hair drug screening particularly challenging.

Confirmation of any positive screening result is conducted via GC/MS, GC/MS/MS, or LC/MS/MS. Samples flagged as presumptive positives are cleansed before confirmation as needed. The complete laboratory process, from Accessioning to Confirmation, adheres to both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug use up to 90 days, unlike urine tests with limited detection times.
• Hard to falsify: Cheating a hair drug test is extremely difficult, enhancing result accuracy.
• Offers historical insight: It reveals drug use patterns over time, not merely recent usage.

Limitations:

• Inability to detect recent use: It takes about 5-7 days before drugs can be traced in hair.
• Expense: Hair drug tests tend to be pricier than other methods.
• Result variability: Influences like hair color and personal differences in growth can impact drug metabolite concentrations.

Note: Commonly described as "hair follicle tests," the analysis is performed 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.
