Hair Follicle Drug Testing - Foster, MT

What it is, How it works

Hair testing is now acknowledged as an effective means for identifying drug and alcohol consumption. Hair captures a historical trace by embedding biomarkers within the fibers of a hair strand as it grows. When gathered near the scalp, hair can reveal a detection period of up to three months for substances like alcohol and drugs. Hair is straightforward to collect, relatively resistant to tampering, and easy to transport.

A 1.5-inch segment comprising around 200 hair strands (equivalent to the thickness of a #2 pencil) next to the scalp yields 100mg of hair, the optimal quantity for both screening and confirming results. For EtG assessments, additional tests, and tests exceeding 10 panels, a 150mg sample is advocated. We advise using a jeweler’s scale to measure the sample. If scalp hair cannot be obtained, an equivalent portion of body hair is acceptable. References to head hair pertain solely to scalp hair, while body hair includes all other types (such as facial and axillary hair).

Process Overview

The principal stages in processing a drug test result in a lab encompass Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial sample integration into a laboratory’s framework. Tasks include ensuring the sample was correctly sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and completing any supplementary data entries that the electronic chain of custody system doesn't cover.

Screening comprises a preliminary rapid test for illicit substances. Although Screening is an economical method to exclude drug usage in the majority of instances, any positive results in screening must undergo confirmation for courtroom acceptance. All samples showing presumptive positivity in Screening necessitate secondary confirmation.

In cases where a sample tests presumptively positive during Screening, additional hair is extracted from the original sample to prepare for Extraction. In this stage, drugs are isolated from hair at significantly lower concentrations compared to other testing methods (e.g., urine or oral fluid), explaining why hair drug testing is notably challenging.

Confirmation for any positively screened sample is executed using GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptively positive samples undergo washing before confirmation as necessary. The entire process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair criteria and the accreditation complying with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can identify drug use for up to 90 days, contrasted with urine tests that have shorter detection spans.
• Challenge in tampering: Cheating a hair drug test is notably difficult, ensuring more precise outcomes.
• Historical usage data: It enables mapping a drug usage pattern over an extended duration, not confined to recent use.

Limitations:

• Lacks recent use detection: Drugs require approximately 5-7 days to become detectable in hair.
• Expense: Hair drug testing typically costs more than alternative drug testing techniques.
• Result variability: Hair color and individual differences in hair growth can impact drug metabolite concentrations in hair.

Note: Frequently dubbed as “hair follicle tests”, the testing 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.

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. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
