Hair Follicle Drug Testing - Fallston, MD

What it is, How it works

Hair testing is widely recognized as an effective method for detecting drug and alcohol usage. By embedding biomarkers within the strands, hair offers a long-term overview of substance use. When taken from near the scalp, it can reveal a 3-month history of alcohol and drug consumption. Hair collection is straightforward, hard to tamper with, and straightforward to transport.

A 1.5-inch piece comprising about 200 strands (roughly matching a #2 pencil’s girth) near the scalp yields 100mg of hair, which is the optimal amount for analysis and confirmation. For EtG assessments, additional tests, or those exceeding 10 panels, 150mg is suggested. It's advisable to weigh the sample using a jeweler’s scale. If scalp hair is not obtainable, the same quantity of body hair could be used. "Head hair" refers exclusively to scalp hair, whereas "body hair" denotes all other types (facial, axillary, etc.).

Process Overview

The four key phases in laboratory processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning incorporates the primary processing of a sample into a lab's system. This step ensures the sample was properly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and completes any requisite data entry not supplied by an electronic chain of custody mechanism.

Screening consists of a preliminary rapid assessment for substance misuse. Although Screening efficiently rules out drug consumption for most samples, a positive outcome needs verification for legal admissibility. Presumptively positive samples in Screening must undergo further confirmation.

For samples testing presumptively positive during Screening, additional hair is extracted from the initial sample for the Extraction phase. Here, drugs are isolated from hair at significantly lower concentrations compared to other tests (urine or oral fluid), presenting hair analysis as the most challenging method to execute.

Confirmation of any preliminary positive Screening outcomes is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples are pre-cleaned as required before confirmation. The lab procedures from Accessioning to Confirmation are subject to review under both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair tests reveal substance use for up to 90 days, outperforming urine tests with shorter detection periods.
• Resistant to manipulation: Cheating on hair drug tests is incredibly difficult, ensuring greater result precision.
• Historical insight: It offers a comprehensive view of drug usage patterns over time, rather than solely capturing recent consumption.

Limitations:

• Non-detection of recent usage: Drugs take about 5-7 days to show up in hair samples.
• Expense: Generally, hair drug tests incur higher costs than other testing methods.
• Result variability: Elements like hair color and individual hair growth rates may influence drug metabolite levels in hair.

Note: Though often termed "hair follicle tests", the analysis pertains to the hair strand rather than the scalp's hair 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.
