Hair Follicle Drug Testing - Big River, CA

What it is, How it works

Hair analysis has emerged as an effective means for identifying drug and alcohol consumption. Hair can offer an extended record of alcohol and other substances by capturing biomarkers within the strands of the growing hair. When taken near the scalp, hair offers approximately a 3-month detection timeframe for alcohol and substances. Hair is easy to collect, quite resistant to tampering, and straightforward to transport.

A 1.5-inch length of roughly 200 hair strands (around the thickness of a #2 pencil) closest to the scalp provides 100mg of hair, which is the optimal sample size for screening and validation. For EtG, additional tests, and/or those beyond 10 panels, a specimen size of 150mg is advisable. We suggest measuring the specimen with a jeweler’s scale. Should scalp hair be unavailable, an equivalent quantity of body hair may be used. References to head hair relate exclusively to scalp hair. Body hair encompasses all other hair forms (facial, axillary, etc.).

Process Overview

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

Accessioning involves the preliminary handling of a sample within a laboratory’s framework. This incorporates confirming the sample was appropriately sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data input absent from an electronic chain of custody system.

Screening encompasses an initial rapid evaluation for substance abuse. While Screening is a budget-friendly method to exclude drug usage in the majority of samples, any positive screen needs confirmation to be valid in legal settings. Any samples appearing presumptively positive during Screening require a follow-up confirmation.

Should a sample yield a presumptively positive result during the Screening phase, additional hair is separated from the original specimen and readied for Extraction. During this phase, substances are isolated from hair at a notably lower concentration than through other methodologies (e.g., urine or oral fluid), which is why hair drug testing presents the most challenging methodology to perform.

The verification of any positive screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation, as required. The entire lab process, from Accessioning to Confirmation, is thoroughly reviewed under both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standard accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug use for up to 90 days, unlike urine tests which have a limited detection period.
• Challenging to manipulate: Hair drug tests are challenging to tamper with, resulting in more accurate outcomes.
• Offers usage history: It reflects a drug use pattern over time, rather than just recent consumption.

Limitations:

• Not suitable for recent detection: It takes roughly 5-7 days for drugs to be traceable in hair.
• Expense: Hair drug tests are typically costlier than other testing methods.
• Result variability: Elements such as hair color and personal variations in hair growth can influence drug metabolite concentrations in hair.

Note: Even though commonly termed as "hair follicle tests", the evaluation involves analyzing the hair strand rather than 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. 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.

Forensic Applications and Interpretation: One of the vital objectives of hair testing is its application in forensic investigations and legal proceedings. The SoHT meeting in Verona emphasized the significance of rigorous interpretation of analytical results and the need for standardized protocols.
