Hair Follicle Drug Testing - Riverdale Park, MD

What it is, How it works

Viewed as a formidable means for identifying drug and alcohol consumption, hair testing captures a comprehensive history of substances by incorporating biomarkers into the strands as they grow. Collected near the scalp, hair offers an observation period of up to roughly three months for alcohol and different drugs. Collection is straightforward, tampering is challenging, and shipping is uncomplicated.

Gathering a 1.5-inch segment of around 200 hair strands (comparable to a #2 pencil) closest to the scalp yields 100mg, optimal for assessment and verification. For EtG additions and/or evaluations exceeding 10 panels, 150mg is advised. It is suggested to measure the sample using a jeweler’s scale. In the absence of scalp hair, an equivalent volume of body hair is an alternative. By head hair, we imply solely scalp hair. Body hair encompasses all other varieties (facial, axillary, etc.).

Process Overview

The laboratory processing of drug test outcomes encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the sample's initial entry into the laboratory system. This process verifies proper sealing and shipment of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data entry missing from an electronic chain of custody system.

Screening is a preliminary, swift test to detect abusive substances. Although cost-efficient for eliminating drug use in the broad spectrum of samples, a positive result in Screening necessitates confirmation for legal admissibility. Any samples with a presumptive positive in Screening require further verification.

If acquired as presumptively positive during the Screening phase, more hair is taken from the original sample for Extraction. This phase involves extracting drugs from hair at significantly lower concentrations than in other methodologies (e.g., urine or oral fluid), demonstrating why hair drug testing poses the highest complexity.

GC/MS, GC/MS/MS or LC/MS/MS is utilized to confirm any positive results from screening. Prior to confirmation where needed, all presumptive positive specimens undergo washing. The laboratory process, from Accessioning to Confirmation, undergoes review under both the CAP (College of American Pathologists) Hair specifications and accreditation under ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended observation period: Hair drug tests track drug use for up to 90 days, in contrast with urine tests, which have shorter observation spans.
• Challenging to deceive: Achieving deception in hair drug testing is extremely difficult, ensuring greater result accuracy.
• Supplies historical insights: Provides a trend in drug usage over time, not merely recent consumption.

Limitations:

• Incapable of detecting recent use: Drugs become noticeable in hair after approximately 5-7 days.
• Expense: Hair drug testing is usually pricier than alternative drug testing approaches.
• Result variability: Variables like hair color and personal differences in hair growth can impact metabolite levels in the hair.

Note: Commonly described as "hair follicle tests", the examination actually targets the hair strand, not the follicle 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.
