Hair Follicle Drug Testing - Dundalk, MD

What it is, How it works

Hair analysis stands as a robust method for unveiling drug and alcohol consumption. Hair archives a timeline of alcohol and drug use by capturing biomarkers within the hair shaft's structure. A segment obtained from near the scalp can offer a detection timeline extending up to three months for various substances. Hair collection is straightforward, challenging to tamper with, and convenient for shipment.

A 1.5-inch section consisting of roughly 200 hair strands (equivalent to the thickness of a #2 pencil) cut near the scalp yields 100mg of hair, an optimal amount for both initial testing and confirmation. When conducting an EtG test, adding panels, or if testing exceeds 10 panels, a 150mg sample is suggested. The specimen should ideally be weighed using a jeweler’s scale. In cases where scalp hair is not available, body hair in an equivalent amount can be collected. When mentioning head hair, it specifically denotes scalp hair. Body hair includes other types (facial, axillary, etc.).

Overview of the Process

The lab processing of drug test outcomes involves four pivotal stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning transforms a sample into the laboratory's records. This step verifies the integrity and shipment of the sample, assigns a random LAN (Laboratory Accessioning Number), and ensures completion of any outstanding data entry not covered by an electronic chain of custody.

Screening conducts a primary evaluation for drugs. Though cost-effective for excluding drug use in most samples, a positive result in Screening must be substantiated for courtroom acceptability. Presumptive positives in Screening necessitate further confirmatory testing.

Samples presumed positive in Screening proceed to Extraction, involving more hair from the initial sample. Here, drugs are isolated at significantly lower levels compared to other methods (ex. urine or oral fluids), highlighting the difficulty of hair drug analysis.

To verify any positive screening outcomes, Confirmation is achieved using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples deemed presumptive positive undergo washing before confirmation as required. The comprehensive laboratory stages, from Accessioning to Confirmation, are subject to review under both CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation standards.

Benefits of hair drug analysis:

• Extended detection period: Hair tests trace drug usage up to 90 days, outlasting urine tests with shorter timelines.
• Hard to deceive: Cheating a hair test is notably difficult, enhancing result reliability.
• Chronicles usage patterns: It illustrates a timeline of drug usage, beyond just recent consumption.

Drawbacks:

• Inability to detect immediate use: Drugs take about 5-7 days to become traceable in hair.
• Expense: Generally, hair tests incur higher costs than alternate drug testing modes.
• Result variability: Resulting concentrations can fluctuate due to factors like hair color and individual growth rates.

Note: The widely used term "hair follicle tests" is somewhat of a misnomer; the analysis pertains to the hair strand itself, not the scalp-embedded 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.
