Hair Follicle Drug Testing - Harrah, WA

What it is, How it works

Hair analysis has gained significance as an effective means for detecting the consumption of drugs and alcohol. Hair offers an extended timeline of alcohol and drug consumption by trapping biological markers within the fibers of the growing strands. When sampled near the scalp, hair can reveal up to three months of drug and alcohol usage. Hair collection is straightforward, challenging to tamper with, and convenient to transport.

A sample measuring 1.5 inches from around 200 hairs, roughly the diameter of a #2 pencil, near the scalp provides 100mg of hair, the perfect sample size for both screening and confirmation. For EtG, additional tests, or panels beyond ten, 150mg of specimen is advised. It's preferable to weigh the specimen on a jeweler’s scale. If scalp hair isn't available, an equivalent quantity of body hair can be gathered. In the context of head hair, we refer specifically to scalp hair. Body hair encompasses all other types (such as facial and axillary hair).

Process Overview

The four major steps in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning incorporates the initial integration of the sample into a lab's system. This step verifies the sample's proper sealing and shipment, assigns a random LAN (Laboratory Accessioning Number), and fills in any supplementary data absent from an electronic chain of custody system.

Screening represents an initial rapid assessment for illicit drugs. While screening efficiently excludes drug use from the majority of samples, a positive screen needs validation for courtroom admissibility. Any samples yielding a tentative positive in Screening demand a follow-up confirmation.

Should a sample test presumptively positive at the Screening phase, additional hair is drawn from the primary specimen for Extraction. This procedure extracts drugs from hair at lower concentrations compared to other techniques (like urine or oral fluid), establishing hair drug screening as a rigorous methodology.

Confirmation of any positive screening result is performed through GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples undergo washing as necessary. The overarching lab procedure from Accessioning to Confirmation falls under review by both the CAP (College of American Pathologists) hair accreditation and recognition to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug assessments can identify drug use spanning up to 90 days, while urine tests have a more limited detection range.
• Hard to alter: Cheating a hair drug test is exceedingly difficult, enhancing result reliability.
• Historical data provision: They can depict a drug use pattern over time, not merely recent consumption.

Limitations:

• Inability to detect recent usage: Drugs typically require 5-7 days to be traceable in hair.
• Expense: Hair drug evaluations are generally pricier than alternative testing approaches.
• Result variability: Factors such as hair pigmentation and individual growth disparities can influence drug metabolite concentration within hair.

Note: Frequently dubbed as "hair follicle tests", the assessment actually examines 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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis. The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix.
