Hair Follicle Drug Testing - Donner, CA

What it is, How it works

Hair testing has emerged as a potent method for identifying drug and alcohol usage. Hair strands offer an extended timeline of substance consumption by embedding biomarkers within the fibers of the developing hair strand. When clipped close to the scalp, hair can reveal a detection window of up to roughly three months for alcohol and drugs. Collecting hair is straightforward, relatively tough to tamper with, and convenient to transport.

A sample length of 1.5 inches consisting of about 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, which serves as the perfect sample amount for examination and verification. For EtG, additions, and/or tests exceeding 10 panels, a specimen weight of 150mg is recommended. Utilizing a jeweler’s scale to weigh the specimen is advisable. If scalp hair is unavailable, an equivalent quantity of body hair can be used. References to head hair specifically imply scalp hair. Body hair encompasses all other hair categories (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result comprises four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial integration of a sample into a lab’s database. This process encompasses verifying the correct sealing and shipment of the sample, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any additional data input omitted by an electronic custody chain system.

Screening constitutes an initial cursory examination for illicit drugs. While Screening offers a budget-friendly method to exclude drug use in numerous samples, any positive result must be authenticated to be considered valid in a legal context. Samples that are presumptively positive during Screening mandate further confirmation.

Should a sample yield a presumptive positive in the Screening phase, additional strands are extracted from the original specimen for the Extraction process. During this stage, drugs are isolated from hair at significantly lower concentrations than in alternative methods (e.g., urine or oral fluid), rendering hair drug screening the most challenging method to execute.

The Confirmation of any positive screening output is executed through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with a presumptive positive require pre-confirmation washing as deemed necessary. The complete laboratory sequence from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection window: Hair drug evaluations can identify drug intake for up to 90 days, unlike urine tests that have a more limited detection period.
• Hard to manipulate: Hair drug tests are particularly challenging to deceive, thus ensuring more precise outcomes.
• Delivers historical insight: They outline a pattern of drug usage over an interval, not solely recent intake.

Limitations:

• Incapable of detecting immediate use: A timeframe of roughly 5-7 days is required for drugs to become traceable in hair strands.
• Expense: Hair drug evaluations generally incur higher costs than other drug testing approaches.
• Variability in outcomes: Elements like hair color and individual hair growth rates can influence the level of drug metabolites present in hair.

Note: Commonly named "hair follicle tests", the analysis is conducted on hair strands, rather than on 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.
