Hair Follicle Drug Testing - Knox, PA

What it is, How it works

Hair testing is regarded as a robust method for detecting drug and alcohol consumption. It provides an extensive record of substance use by embedding biomarkers in the strands as they grow. When sourced near the scalp, hair can offer approximately a 3-month retrospective window for detecting drugs and alcohol. This method is straightforward to perform, relatively resistant to tampering, and convenient for transport.

A hair specimen measuring 1.5 inches, consisting of around 200 strands (similar to the width of a #2 pencil), yields about 100mg, which is optimal for both screening and confirmation tests. For comprehensive tests, such as EtG, additional panels over 10 require 150mg. It's advisable to use a jeweler’s scale for precision. In the absence of scalp hair, an equivalent quantity of body hair is acceptable. 'Head hair' specifically refers to scalp hair, while 'body hair' covers all other types (e.g., facial, axillary).

Process Overview

The laboratory procedures for processing drug test results encompass four essential phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the beginning of sample processing within a laboratory system, ensuring the sample is properly sealed and delivered, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not covered by an electronic chain of custody system.

Screening offers a preliminary assessment for substances of abuse. Although Screening is a cost-efficient means for negating drug use in most samples, positive results require further Confirmation to be valid for legal purposes. Any samples flagged during Screening need a subsequent confirmation step.

Should the Screening phase indicate a presumptive positive, additional hair from the original sample is used for Extraction. This phase involves extracting drugs from the hair at concentrations lower than those in other techniques like urine or oral fluid testing, making hair drug screening particularly challenging.

Confirmation of positive screening outcomes is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. Before Confirmation, all presumptive positive samples are washed if necessary. This entire laboratory process, from Accessioning to Confirmation, undergoes rigorous review under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Prolonged detection window: Hair testing can identify drug use up to 90 days after it occurs, surpassing the shorter detection times of urine tests.
• Hard to deceive: Cheating a hair drug test is challenging, thereby enhancing result reliability.
• Chronological data provision: It offers insights into drug use trends over time, not solely recent activity.

Limitations:

• Inability to detect recent usage: Drugs become traceable in hair approximately 5-7 days post-use.
• Expense: Hair drug tests generally incur higher costs than alternative testing methods.
• Result variability: Elements such as hair color and individual hair growth characteristics can influence drug metabolite concentrations in hair samples.

Note: Commonly termed "hair follicle tests", these actually examine the hair strand itself, not the subscalp 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.
