Hair Follicle Drug Testing - Exum, TX

What it is, How it works

Hair testing has emerged as an effective method for detecting drug and alcohol consumption. Hair offers a long-term drug and alcohol timeline by embedding biomarkers within the fibers of the growing hair strand. When collected near the scalp, hair can provide a detection window spanning up to roughly 3 months for alcohol and other substances. Hair collection is straightforward, somewhat resistant to tampering, and easy to mail.

A 1.5-inch sample of about 200 hair strands (comparable to the size of a #2 pencil) near the scalp will yield 100mg of hair, the optimal specimen for screening and confirmation. For EtG, additional panels, and/or tests exceeding 10 panels, 150mg of the sample is advised. It is suggested to measure the sample on a jeweler’s scale. If scalp hair is unavailable, an equivalent amount of body hair may be used. Reference to head hair is exclusive to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result typically involves four pivotal steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning consists of the initial entry of a sample into a lab's system. This process ensures the sample was sealed and dispatched correctly, assigns a random LAN (Laboratory Accessioning Number), and finalizes any additional data input not covered by an electronic chain of custody system.

Screening is an initial swift assessment for abuse drugs. While Screening offers a cost-effective method to disregard drug use in most samples, a positive screen requires verification for court admissibility. Any samples flagged as presumptively positive in Screening necessitate secondary confirmation.

If a sample is flagged as presumptively positive during the Screening stage, more hair is taken from the initial specimen and prepared for Extraction. In this phase, drugs are extracted from hair at significantly lower concentrations compared to other methodologies (e.g., urine or oral fluid), underscoring the complexity of hair drug screening.

Confirmation of any positive screening result occurs via GC/MS, GC/MS/MS or LC/MS/MS. All presumed positive samples are cleansed before confirmation if needed. The entire lab process from Accessioning through Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use up to 90 days, unlike urine tests with a more limited detection period.
• Difficult to manipulate: Cheating a hair drug test is significantly challenging, thus enhancing the accuracy of results.
• Supplies historical data: It reveals a drug use pattern over time, not merely recent consumption.

Limitations:

• Inability to detect recent consumption: Drugs require approximately 5-7 days to be traceable in hair.
• Expense: Hair drug tests tend to be pricier than other drug testing techniques.
• Result variations: Elements such as hair color and personal hair growth differences can influence drug metabolite concentration in hair.

Note: Though commonly termed "hair follicle tests", the analysis targets the hair strand, not the hair 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.
