Hair Follicle Drug Testing - Grotto, WA

What it is, How it works

Hair analysis is recognized as a potent method for detecting drug and alcohol consumption. It offers a comprehensive history of alcohol and drug exposure by capturing biomarkers within the fibers of the hair as it grows. When taken near the scalp, hair samples can reveal consumption patterns for up to about three months. The collection process for hair is straightforward, it is relatively resistant to tampering, and it is easy to mail.

A hair sample measuring 1.5 inches with roughly 200 strands (approximating the size of a #2 pencil) next to the scalp amounts to 100mg, which is ideal for both initial screenings and confirmations. For tests like EtG, add-ons, or those exceeding 10 panels, 150mg is advised. We suggest using a jeweler’s scale to weigh the sample. If scalp hair is unavailable, a comparable amount of body hair can be used. Head hair specifically refers to scalp hair, while body hair encompasses all other types (such as facial and axillary hair).

Process Overview

The procedural steps in the lab for processing drug test results include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary step where a sample is logged into a lab’s system. This phase includes ensuring that the sample was correctly sealed and sent, assigning a unique LAN (Laboratory Accessioning Number), and completing any extra data entry not provided through an electronic chain of custody.

Screening is an initial rapid assessment for signs of drug use. While Screening is an economical way to exclude drug use in most cases, a positive screen requires confirmation to be valid legally. Any samples with a presumptive positive result during Screening must undergo secondary confirmation.

If a sample yields a presumptive positive result at the Screening phase, additional hair from the initial sample is used for Extraction. Drugs are extracted from hair at considerably lower concentrations than other methods (like urine or oral fluid), making hair drug screening a complex methodology.

For Confirmation, any positive screening result is verified through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results are cleansed before confirmation as necessary. The entire lab process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair guidelines and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can trace drug use for as much as 90 days, whereas urine tests have a shorter detection period.
• Hard to manipulate: Cheating a hair drug test is quite challenging, enhancing the accuracy of results.
• Retrospective data: It offers a usage pattern over time, not just recent consumption.

Limitations:

• Inability to detect immediate use: There is a 5-7 day lag for drugs to become visible in hair.
• Expense: Hair drug tests are typically more costly compared to other methods.
• Result variability: Factors such as hair color and individual differences in hair growth can influence the presence of drug metabolites in the hair.

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