Hair Follicle Drug Testing - Lind, WA

What it is, How it works

Hair testing serves as an effective method for identifying drug and alcohol consumption. The hair captures a comprehensive record of alcohol and drug use by encapsulating biomarkers within its strands. When sampled near the scalp, hair can detect alcohol and other substances over an approximate three-month period. Its collection is straightforward, manipulation is fairly challenging, and it is easy to transport.

A sample of approximately 200 hair strands measuring 1.5 inches (roughly the diameter of a #2 pencil) collected from the scalp will yield 100mg, the perfect quantity for both screening and confirmation. For EtG, additional tests, or panels exceeding 10, a specimen amounting to 150mg is advisable. It's suggested to measure the specimen using a jeweler's scale. If scalp hair is inaccessible, an equivalent quantity of body hair can be obtained. References to head hair imply only scalp hair, while body hair encompasses all other forms (such as facial or axillary).

Process Overview

The procedure for processing a drug test result in a lab consists of four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the first step where a sample is introduced into the lab's system. It involves confirming the sample's intact sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and performing any additional data entry absent from an electronic chain of custody.

Screening performs an initial swift check for substance abuse. Although Screening provides a cost-effective measure to eliminate doubts on most samples, any positive screen demands confirmation to stand up in legal proceedings. Samples deemed presumptive positive undergo a second confirmation.

Should a sample show presumptive positivity at the Screening phase, additional hair is taken from the original sample and formatted for Extraction. In this phase, drugs are removed from hair at significantly lower concentrations than other methodologies (such as urine or oral fluid), hence making hair drug screening notably challenging to execute.

Confirmation of any positive screening outcome is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All samples deemed presumptive positive are cleansed before confirmation as necessary. The complete lab process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can monitor drug intake for up to 90 days, unlike urine tests that have a shorter detection time frame.
• Difficulty to cheat: Cheating a hair drug test is considerably difficult, resulting in more precise outcomes.
• Provides historical data: It offers a usage pattern over a period, not solely recent consumption.

Limitations:

• Cannot detect recent use: Drugs take about 5-7 days to become traceable in hair strands.
• Cost: Generally, hair drug tests incur higher expenses compared to other testing techniques.
• Variations in results: Hair color and individual hair growth variations can impact drug metabolite levels in hair.

Note: Although commonly known as "hair follicle tests", the actual analysis is conducted on the hair strand 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.
