Hair Follicle Drug Testing - Gilead, NE

What it is, How it works

The efficacy of hair testing as a discerning method for identifying drug and alcohol use has gained recognition. Hair inherently captures long-term drug and alcohol usage by encasing biomarkers within the structure of the maturing hair strand. When sourced near the scalp, hair offers an approximate 3-month timeframe for detecting alcohol and other substances. The process of hair collection is straightforward, hard to tamper with, and easily transportable.

An optimal sample, approximately 1.5-inch of around 200 hair strands (about the diameter of a #2 pencil) nearest to the scalp, will yield 100mg of hair, making it ideal for screening and confirmation procedures. For EtG, additional tests, or panels exceeding 10, 150mg of hair is advisable. We recommend that the specimen be weighed using a jeweler's scale. In cases where scalp hair cannot be obtained, an equivalent quantity of body hair can be gathered. Head hair here pertains solely to scalp hair. Body hair encompasses all other hair forms (facial, axillary, etc.).

Process Overview

There are four pivotal steps in the laboratory examination process of a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.

Initial sample processing within a laboratory system is under the purview of Accessioning. This step entails the confirmation that the sample was sealed and transported properly, allocating a unique LAN (Laboratory Accessioning Number), and completing outstanding data entry not handled by an electronic chain of custody system.

Screening provides a preliminary, swift evaluation for drugs of abuse. Although Screening offers an economical method to exclude drug usage in the majority of samples, legal admissibility of a positive screening result necessitates confirmation. Subsequently, any samples suspected positive at the Screening phase must undergo further verification.

Noticeably positive samples from the Screening step require additional hair from the initial sample for the Extraction process. During Extraction, drugs are isolated from hair in significantly lower concentrations in comparison to other methods (e.g., urine or oral fluid), which attributes to the complexity of hair drug testing over other techniques.

Positive Screening results that require verification are validated via GC/MS, GC/MS/MS, or LC/MS/MS. Necessary samples presumed positive are cleansed before confirmation. The complete procedural journey from Accessioning to Confirmation undergoes thorough review under both the CAP (College of American Pathologists) Hair distinction and adherence to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Prolonged detection timeframe: Hair drug tests can trace drug usage up to 90 days, unlike urine tests that have a more restricted detection period.
• Test integrity: Cheating a hair drug test is extremely challenging, thus enhancing result reliability.
• Chronological substance use data: It reveals a timeline of drug usage, offering more than just insight into recent consumption.

Limitations:

• Lacks recent conduct detection: Drugs become discernible in hair after approximately 5-7 days.
• Testing expense: Generally, hair drug assays bear greater costs than other drug diagnostic methods.
• Result variability: Differences including hair color and personal hair growth rates can impact the concentration of drug metabolites within hair samples.

Note: Though colloquially known as "hair follicle tests", the test truly evaluates the hair strand, not the sub-dermal follicle.

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.
