Hair Follicle Drug Testing - Aberdeen, WA

What it is, How it works

Utilizing hair testing has increasingly become recognized as an effective method for identifying drug and alcohol consumption. Hair serves as a long-term record of substance use by encapsulating biomarkers within the strands of growing hair. When collected near the scalp, hair can reveal up to a three-month history of alcohol and other substances. It's easy to collect, relatively hard to tamper with, and convenient to send.

A 1.5-inch segment near the scalp, consisting of about 200 hairs (equivalent to the thickness of a #2 pencil), yields approximately 100mg, which is the ideal amount for assessment and verification. For EtG, additional tests, and/or panels exceeding ten, a 150mg sample is suggested. It's advisable to weigh the sample on a jeweler’s scale. If scalp hair is not an option, a comparable quantity of body hair may be utilized. "Head hair" specifically refers to scalp hair, whereas "body hair" encompasses all other types (e.g., facial, axillary).

Process Overview

The laboratory handling of drug test results consists of four important phases: Accessioning, Screening, Extraction, and Confirmation.

The Accessioning phase includes the intake and processing of a sample within the lab's system, which involves ensuring the sample's proper sealing and shipping, allocating a unique LAN (Laboratory Accessioning Number), and completing any missing data not available in an electronic chain of custody system.

The Screening phase provides an initial cost-effective assessment to rule out drug use for most specimens; however, a positive result in this stage must undergo confirmation to be legally acceptable. Samples indicating a presumptive positive in Screening require further verification.

When a sample signals a presumptive positive during Screening, additional hair is extracted from the original sample and set up for Extraction. In this procedure, drugs are retrieved from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), making hair drug testing particularly challenging.

Any positive result from screening is subsequently confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, presumptively positive samples are cleaned as necessary. The entire process, from Accessioning to Confirmation, is vetted following both the CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can trace substance use for up to 90 days, contrasting with urine tests that offer a shorter detection span.
• Hard to manipulate: The difficulty in falsifying a hair drug test enhances result accuracy.
• Provides past usage patterns: Offers a view of substance use over time rather than just recent consumption.

Limitations:

• Limited recent detection: Drugs need about 5-7 days to be traceable in hair.
• Higher expense: Hair drug tests are often pricier than alternative testing methods.
• Outcome variability: Elements such as hair color and individual growth rates might impact drug metabolite concentrations in hair.

Note: Though commonly called "hair follicle tests", the procedure analyzes the hair strand, not the follicle under 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.
