Hair Follicle Drug Testing - Grady, OK

What it is, How it works

Hair analysis is now recognized as an effective means to detect alcohol and drug consumption. By capturing biomarkers within the fibers of the growing strand, hair offers a comprehensive historical view of drug and alcohol use. When collected from the scalp, hair can reveal drug and alcohol use spanning roughly three months. The collection of hair is straightforward, less prone to tampering, and easy to transport.

A 1.5-inch sample consisting of approximately 200 strands (comparable to a #2 pencil) closest to the scalp will amount to 100mg, which is the optimal quantity for both screening and confirmatory tests. For EtG, additional tests, and/or panels exceeding ten, a 150mg sample is advised. Utilizing a jeweler's scale to measure the specimen is recommended. In the absence of scalp hair, an equivalent quantity of body hair may be obtained. References to head hair imply scalp hair specifically. "Body hair" encompasses all non-scalp hair types (e.g., facial, axillary).

Process Overview

The laboratory procedure for processing a drug test result comprises four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves incorporating a sample into a laboratory’s framework. This stage includes ensuring the sample was correctly sealed and dispatched, allocating a unique LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry missing from an electronic custody chain system.

Screening is a preliminary assessment for illicit substances. While cost-effective for excluding drug use in most samples, positive results require confirmation for legal acceptability. Any Screening-phase samples that are tentatively positive need subsequent validation.

Should a sample test tentatively positive during Screening, additional hair is extracted from the initial sample and set for Extraction. At this stage, drugs are extracted from hair at a significantly reduced concentration compared to other methods (such as urine or oral fluid), making hair drug screening the most challenging method to conduct.

Confirmation of any positive Screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as necessary. From Accessioning to Confirmation, each laboratory stage is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug use for up to 90 days, contrasting with urine tests' shorter detection spans.
• Tough to deceive: Hair drug tests are notably difficult to manipulate, ensuring more precise outcomes.
• Tracks historical usage: These tests provide insight into drug use trends over time, beyond just recent intake.

Limitations:

• Does not reveal recent usage: Drugs take around 5-7 days to show up in hair.
• Expense: Hair drug tests typically incur higher costs than other testing methods.
• Diversity in results: Variables such as hair color and individual differences in hair growth can impact drug metabolite concentrations in hair.

Note: Although frequently termed as "hair follicle tests", the procedure actually assesses 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.
