Hair Follicle Drug Testing - Dillard, OR

What it is, How it works

Hair analysis is regarded as an effective method for identifying drug and alcohol consumption. Hair retains a long-term record of substances by capturing indicators within the fibers of the growing strands. When obtained near the scalp, hair can present a detection period of up to roughly 3 months for these substances. Gathering hair is straightforward, fairly tamper-resistant, and convenient to transport.

A sample measuring 1.5 inches of approximately 200 hair strands (comparable to the diameter of a #2 pencil) nearest the scalp should yield 100mg of hair, an optimal amount for both screening and subsequent verification. For EtG, additional analyses, and/or tests exceeding 10 panels, 150mg of the specimen is advised. It's best to use a jeweler’s scale to weigh the sample. If scalp hair isn’t accessible, an equivalent amount of body hair can be obtained. By head hair, we mean scalp hair alone. Body hair indicates any other types (facial, axillary, etc.).

Process Overview

The core steps in laboratory drug testing are Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a sample into the lab's system. This phase ensures the sample was sealed and shipped correctly, assigns a random LAN (Laboratory Accessioning Number), and finalizes any extra data input absent in an electronic chain of custody system.

Screening is a preliminary assessment for drug presence. While it’s a cost-effective way to rule out drug usage in the majority, a positive screen must be confirmed for legal admissibility. Tests indicating a potential positive result during Screening need retesting for validation.

Should a sample show a probable positive result in Screening, additional hair is extracted from the original sample for Extraction. At this stage, drugs are extracted from hair at significantly lower concentrations than other methodologies (e.g., urine or oral fluid), explaining why hair drug analysis is among the most intricate techniques to apply.

Substantiation of any positive screen result is carried out via GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are cleansed prior to confirmation if necessary. Each phase from Accessioning through Confirmation undergoes a review under both the CAP (College of American Pathologists) Hair guidelines and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection duration: Hair drug exams can trace drug use for up to 90 days, unlike urine exams with shorter detection spans.
• Cheating resistance: Hair drug tests are notably hard to deceive, resulting in more reliable outcomes.
• Provides historical trends: It can display drug usage trends over time, not merely recent consumption.

Limitations:

• Lacks recent use detection: Drugs require roughly 5-7 days to manifest in hair.
• Expense: Hair drug examinations usually cost more than other testing approaches.
• Variability in results: Factors like hair color and personal growth rates can influence drug metabolite concentrations in hair.

Note: Commonly termed "hair follicle tests," the procedure evaluates the hair strand itself 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.
