Hair Follicle Drug Testing - Limestone, MT

What it is, How it works

Hair analysis is increasingly recognized as an effective means for detecting substance use, both alcohol and drugs. This method leverages hair's ability to preserve traces of substances over extended periods by embedding biomarkers within the strands. A sample taken nearest the scalp can offer a detection period of roughly three months for both alcohol and drugs. Collecting hair is straightforward, tampering proves challenging, and shipping it is uncomplicated.

Gathering a 1.5-inch segment consisting of approximately 200 hairs (resembling a #2 pencil in thickness) from near the scalp will yield 100mg of hair, which is ideal for both screening and confirmation. For evaluations involving EtG, supplements, and/or tests exceeding 10 panels, a specimen of 150mg is advised. It's recommended to weigh the sample using a jeweler’s scale. If head hair is unavailable, a comparable quantity of body hair can be used. Mention of head hair specifically refers to scalp hair, while body hair encompasses other types (like facial or axillary hair).

Process Overview

The quartet of critical stages in laboratory testing for drug presence includes Accessioning, Screening, Extraction, and Confirmation.

Accessioning denotes the preliminary processing stage of a sample into a laboratory's system. This involves checking the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data input not available from an electronic chain of custody system.

Screening executes an initial swift assessment for addictive substances. While Screening is cost-efficient for excluding drug use in most samples, a positive result must undergo confirmation to be valid in legal settings. Any samples initially suspected positive in Screening require secondary confirmation.

When Screening suggests a positive result, additional hair is drawn from the initial sample and readied for Extraction. At this phase, drugs are extracted from hair at much lesser concentrations than other methods (such as urine or oral fluid), explaining why hair drug screening is complex.

Confirming any positive screening outcome happens through GC/MS, GC/MS/MS, or LC/MS/MS. Every suspected positive sample undergoes washing before confirmation as necessary. The full lab process from Accessioning through Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests offer detection capability for up to 90 days, which is longer than the detection period for urine tests.
• Cheating difficulty: It is exceptionally difficult to meddle with a hair drug test, thereby enhancing result reliability.
• Historical insight: Provides a trend in drug use over time, unlike tests that only show recent usage.

Limitations:

• Indirect detection of recent usage: There's a 5-7 day window before substances are detectable in hair.
• Expense: Hair drug testing is generally more pricey than alternative testing techniques.
• Result variability: Factors such as hair pigmentation and individual growth differences can influence the level of drug metabolites in hair.

Note: Although commonly called "hair follicle tests", the analysis targets the hair shaft 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.

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.
