Hair Follicle Drug Testing - Demotte, IN

What it is, How it works

Hair analysis is widely regarded as an effective method for identifying alcohol and drug consumption. Hair acts as a historical record for substances by embedding biomarkers within the strands as they grow. Obtained from near the scalp, hair can reflect alcohol and drug usage for up to a three-month period. It is easy to collect, hard to tamper with, and simple to transport.

A 1.5-inch segment from about 200 hair strands (approximately the width of a #2 pencil) taken closest to the scalp provides 100mg of hair, the optimal sample for both screening and confirmation. For EtG, additional tests, or panels exceeding 10, a 150mg sample is recommended. It's suggested to use a jeweler’s scale to weigh the sample. If scalp hair isn't available, an equivalent amount of body hair can be taken. Note that head hair refers specifically to scalp hair, while body hair includes facial, axillary, and other types.

Overview of Procedure

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

Accessioning is the initial step where a sample is formally registered in a lab's system, involving checks for proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not covered by an electronic chain of custody system.

Screening involves a preliminary evaluation for drug presence. While Screening serves as a cost-efficient method to exclude drug use for most samples, a positive screening result requires confirmation for legal admissibility. All samples testing presumptively positive in Screening necessitate further confirmation.

For samples indicated as presumptively positive during Screening, additional hair is extracted from the original sample for the Extraction phase. At this point, substances are isolated from the hair at much lower concentrations than other testing methods (like urine or oral fluid), contributing to the complexity of performing hair drug tests.

Any confirmed positive result from the Screening process is verified using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive findings undergo washing prior to confirmation if needed. The complete laboratory process from Accessioning through Confirmation is validated under both the CAP (College of American Pathologists) Hair designation and accreditation per ISO / IEC 17025 standards.

Benefits of hair drug testing:

• Extended detection timeline: Hair drug evaluations can identify drug use for up to 90 days, in contrast to urine tests with shorter time frames.
• High difficulty in deception: Cheating a hair drug test is particularly challenging, leading to more precise outcomes.
• Chronological usage data: It offers insights into drug consumption patterns over an extended period instead of just recent usage.

Limitations:

• Cannot detect recent usage: Detection in hair requires about 5-7 days post-consumption for drugs to be identifiable.
• Expense: Hair drug assessments tend to be costlier than alternative drug testing approaches.
• Result variability: Elements like hair color and unique hair growth characteristics impact drug metabolite concentration in hair.

Note: Despite often being called "hair follicle tests", the testing procedure actually examines 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.
