Hair Follicle Drug Testing - Salunga, PA

What it is, How it works

Hair testing is considered an effective method for identifying drug and alcohol consumption. The hair captures a long-term trail of alcohol and drug presence by embedding biomarkers in the fibers of the hair as it grows. A sample taken close to the scalp can reflect drug and alcohol use over a timespan of up to three months. Hair collection is straightforward, challenging to tamper with, and convenient for transportation.

A sample of 1.5 inches consisting of about 200 hair strands (equating to the thickness of a #2 pencil) taken nearest the scalp provides 100mg of hair, which is the optimal quantity for screening and verification. For EtG, additional tests, or panels exceeding 10, a sample of 150mg is advised. Using a jeweler’s scale to weigh the sample is recommended. If scalp hair is not an option, an equivalent quantity of body hair can be collected. References to head hair specifically mean scalp hair, while body hair encompasses all other types (such as facial, axillary, and others).

Process Overview

The lab processing of a drug test is comprised of four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial phase of entering a sample into the lab's framework. This stage includes ensuring the sample's seal and shipment integrity, generating a random LAN (Laboratory Accessioning Number), and filling in any missing data that's not captured by an electronic chain of custody system.

Screening acts as a preliminary assessment for substance abuse. Although it is a cost-efficient technique for excluding drug use in most samples, a positive result in Screening necessitates confirmation for legal acceptability. Samples testing presumptively positive in Screening must undergo further confirmation.

For presumptively positive samples after Screening, additional hair is extracted from the original sample and processed for Extraction. In this step, drugs are isolated from hair at much lower concentrations than other methods (such as urine or oral fluids), which makes hair drug screening particularly challenging to execute.

Confirmation of any positive result from screening is accomplished using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleansed as required before confirmation. The complete lab process from Accessioning to Confirmation is scrutinized both under the CAP (College of American Pathologists) Hair guidelines and ISO/IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug use for up to 90 days, whereas urine tests have a shorter detection timeframe.
• Difficult to manipulate: Cheating a hair drug test is highly challenging, ensuring more precise outcomes.
• Offers cumulative data: It can illustrate a pattern of drug consumption over time, not just recent activity.

Limitations:

• Unable to detect recent use: Drugs become detectable in hair only after about 5-7 days.
• Expense: Hair drug testing generally incurs higher costs than other testing approaches.
• Result discrepancies: Factors like hair color and individual growth rates can influence drug metabolite concentration in hair.

Note: Commonly referred to as "hair follicle tests", the test examines the hair strand itself, not the follicle beneath the skin.

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.
