Hair Follicle Drug Testing - White Water, CA

What it is, How it works

Hair analysis is recognized as an effective method for identifying substance and alcohol consumption. The hair captures long-term consumption evidence by embedding biomarkers within the hair as it grows. When taken from the scalp area, hair provides a detection period of up to about three months for substances and alcohol. Gathering hair is straightforward, less prone to tampering, and easy to transport.

A 1.5-inch section of approximately 200 hair strands (comparable to a #2 pencil's thickness) nearest the scalp offers 100mg of hair, which is the preferred sample size for both initial tests and confirmations. It's advised to determine the specimen's weight using a jeweler’s scale for EtG, add-ons, and tests exceeding 10 panels, where 150mg is preferable. Should scalp hair be unavailable, a comparable volume of body hair may be used. "Head hair" only pertains to scalp hair, whereas "body hair" encompasses all other types (facial, axillary, etc.).

Process Overview

There are four crucial stages in processing a laboratory drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the first phase where a specimen is incorporated into a laboratory’s system, involving confirmation that it was appropriately sealed and dispatched, the assignment of a random LAN (Laboratory Accessioning Number), and any supplementary data entry that is not part of an electronic chain of custody setup.

Screening entails a preliminary assessment for illicit substances. Although Screening is an economical technique for excluding drug use in most specimens, any positive result requires confirmation for courtroom admissibility. Samples that are preliminarily positive during Screening mandate further confirmation.

If Screening indicates a presumptive positive, additional hair is extracted from the preliminary specimen for further Extraction. During this phase, substances are extracted from hair at much lower concentrations than other techniques (e.g., urine or oral fluid), which makes hair drug screening exceptionally challenging.

To affirm any positive screening outcome, tests like GC/MS, GC/MS/MS, or LC/MS/MS are employed. All presumptively positive samples are cleansed prior to confirmation as necessary. The full laboratory cycle from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair categorization and the accreditation standards of ISO / IEC 17025.

Advantages of hair drug testing:

• Extended detection period: Hair drug analyses can trace drug use up to 90 days, whereas urine tests have a much shorter detection frame.
• Difficult to deceive: Tampering with a hair drug test is notably difficult, thus ensuring more reliable outcomes.
• Shows usage patterns: It reveals usage trends over time, not merely recent consumption.

Limitations:

• Lack of recent use detection: Detection in hair tests takes about 5-7 days post-consumption.
• Expense: Hair drug analyses tend to be pricier than other testing approaches.
• Result variability: Elements like hair color and individual growth differences can influence drug metabolite concentrations within hair.

Note: Often denoted as "hair follicle tests", the examination is of the hair strand itself and 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. 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.
