Hair Follicle Drug Testing - Macedonia, GA

What it is, How it works

Hair assessments have emerged as a strong instrument for detecting substance and alcohol consumption. Hair holds extended records of alcohol and substances by capturing biomarkers inside the fibres of the developing hair strand. When gathered near the scalp, it can offer an approximate three-month window for detecting alcohol and drugs. Hair is easy to gather, resistant to tampering, and straightforward to transport.

A sample of 1.5 inches, consisting of around 200 hair strands (roughly the size of a #2 pencil) closest to the scalp will provide 100mg of hair, the optimal amount for testing and verification. For EtG, additions, and/or over 10 panel tests, a 150mg sample is suggested. It is advised to weigh the specimen using a jeweler’s scale. Should scalp hair be unavailable, a corresponding amount of body hair may be used. References to head hair indicate scalp hair exclusively. Body hair refers to all other hair (facial, axillary, etc.).

Process Overview

The primary steps in the lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the preliminary processing of a sample into a lab’s system. It features confirming that the sample was correctly sealed and sent, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry absent from an electronic chain of custody system.

Screening entails an initial rapid assessment for substance misuse. Though Screening is a budget-friendly way to eliminate drug use in many samples, a positive screen needs confirmation for court acceptance. Any samples that are provisionally positive in Screening require a follow-up confirmation.

In cases where a sample is provisionally positive during the Screening phase, extra hair is extracted from the original specimen and readied for Extraction. During this phase, substances are withdrawn from hair at significantly lower concentrations than in other methods (e.g., urine or saliva), making hair drug testing the most complex method to conduct.

Verification of any positive screening outcome is performed via GC/MS, GC/MS/MS or LC/MS/MS. All provisional positive samples are cleansed before confirmation as needed. The complete lab procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair classification and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection span: Hair drug tests can identify substance use for up to 90 days, unlike urine tests that have a shorter detection span.
• Challenge to deceive: It is notably challenging to beat a hair drug test, providing more accurate outcomes.
• Offers chronological data: It can demonstrate a drug use pattern over time, not only recent use.

Limitations:

• Unable to detect recent use: It generally takes 5-7 days for substances to become traceable in hair.
• Costs: Hair drug tests typically incur higher costs than other drug testing techniques.
• Variability in outcomes: Elements such as hair color and individual differences in hair growth can influence the concentration of drug metabolites in hair.

Note: Often termed as "hair follicle tests", the test examines the hair strand rather than the follicle underneath 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.
