Hair Follicle Drug Testing - Kingsville, MD

What it is, How it works

Hair analysis has emerged as an effective means for identifying alcohol and drug consumption. Within the strands of growing hair, biomarkers of alcohol and drugs are encapsulated, offering a prolonged timeline of substance use. Sampling hair near the scalp permits a detection span of roughly 90 days for such substances. This method of collection is straightforward, somewhat resistant to tampering, and convenient to transport.

Obtaining a 1.5-inch segment of approximately 200 hair strands (comparable to the size of a #2 pencil) close to the scalp yields 100mg, the optimal quantity for evaluation and verification. For EtG additions and tests exceeding 10 panels, a recommendation of 150mg is advised. Using a jeweler’s scale is suggested for weighing. If hair from the scalp is not available, an equivalent quantity of body hair can be sampled. Note that when discussing head hair, we specifically mean scalp hair. Body hair comprises other types such as facial and axillary hair.

Process Overview

The drug testing laboratory procedure comprises four key phases: Accessioning, Screening, Extraction, and Confirmation.

In Accessioning, the sample initially enters the laboratory's system, ensuring proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and inputting any additional data beyond an electronic chain of custody.

Screening serves as a preliminary check for abused substances. This cost-efficient step is effective for most samples, but any detected positive requires confirmation for legal standards. Those that test positive during Screening necessitate a further confirming analysis.

Should a presumptive positive arise at the Screening stage, additional hair from the sample is prepared for Extraction. Here, drugs are extracted from hair at notably lower concentrations compared to other techniques (e.g., urine or oral fluid), making hair drug testing the most challenging to execute.

Confirmation of any initial positive screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Samples found to be presumptively positive undergo washing before confirmation as the situation demands. Throughout the process from Accessioning to Confirmation, there is adherence to CAP (College of American Pathologists) Hair guidelines and compliance with ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection span: Hair drug assessments can identify drug use over a period of up to 90 days, a longer duration than urine tests.
• High resistance to tampering: The difficulty in tampering with hair drug assessments enhances their accuracy.
• Historical insight: It provides an historical overview of substance use over time, not just immediate usage.

Limitations:

• Inability to detect recent use: A lag of about 5-7 days exists before drugs become traceable in hair.
• Higher cost: Hair analysis generally incurs more expenses compared to other testing approaches.
• Result variability: Differences like hair color and individual growth rates can influence the concentration of drug metabolites found in hair.

Note: The term "hair follicle tests" is misleading as the analysis focuses on the hair strand rather than the follicle located 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.
