Hair Follicle Drug Testing - Allison Park, PA

What it is, How it works

Hair analysis has emerged as a robust method for detecting drug and alcohol consumption. Hair captures a long-term record of alcohol and drug use by embedding biomarkers in the strands as hair grows. When gathered near the scalp, hair can offer roughly a 90-day detection period for both alcohol and drugs. Collecting hair is straightforward, relatively resistant to tampering, and convenient to transport.

A segment of hair measuring 1.5 inches, approximately 200 strands (comparable to a #2 pencil), taken nearest to the scalp, will yield 100mg of hair, which is the optimal sample size for testing and validation. For EtG, additional tests, or assays exceeding 10 panels, it is advised to collect 150mg of the sample. We suggest measuring the sample with a jeweler’s scale. In the absence of scalp hair, an equivalent quantity of body hair can be used. When mentioning head hair, we specifically mean scalp hair. Body hair encompasses other hair types (facial, axillary, etc.).

Process Overview

The key stages in the laboratory evaluation of a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial integration of a sample into a lab system. This phase confirms the sample's proper sealing and transport, assigns a random LAN (Laboratory Accessioning Number), and completes any missing data entry not supplied by an electronic chain of custody system.

Screening is a preliminary assessment for drugs of abuse. Although Screening offers an economical method to dertermine drug absence in most samples, a positive result must be corroborated for legal acceptability. Samples with a presumed positive result in Screening require additional confirmation.

In instances where a Screening stage result is presumed positive, additional hair is extracted from the initial sample for the Extraction phase. Here, drugs are extracted from hair at significantly lower concentrations compared to other methods (such as urine or oral fluid), which is why hair drug testing is the most challenging method to execute.

Verification of any positive Screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive outcomes are washed before confirmation as necessary. The entire laboratory procedure, from Accessioning to Confirmation, is examined under both the CAP (College of American Pathologists) Hair certification and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug assays can detect drug use for up to 90 days, unlike urine tests which have a shorter detection period.
• Difficult to undermine: It is exceedingly hard to manipulate a hair drug assay, yielding more reliable results.
• Historical usage data: It provides a timeline of drug usage, not just recent activity.

Limitations:

• Cannot detect recent usage: It requires around 5-7 days for drugs to become traceable in hair.
• Expense: Hair drug assays are typically more costly than alternative drug testing techniques.
• Result variability: Elements like hair color and differences in hair development can impact the concentration of drug metabolites in the hair.

Note: Although often termed "hair follicle tests", the examination focuses on the hair strand, not the hair follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why Hair Follicle Testing Outperforms Urine Testing in Allison Park, PA

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.
