Hair Follicle Drug Testing - Rosaryville, MD

What it is, How it works

Hair analysis has emerged as a formidable method for detecting drugs and alcohol. Hair captures a prolonged timeline of alcohol and drug consumption by securing biomarkers within the keratin of the growing strand. When clipped near the scalp, hair offers up to a 90-day window for detecting drugs and alcohol. Collection is straightforward, tampering is relatively challenging, and transport is uncomplicated.

A 1.5-inch specimen comprising roughly 200 strands (similar in width to a #2 pencil) near the scalp provides 100mg, the optimal amount for assessment and validation. For EtG, additional assessments, and/or tests exceeding 10 panels, 150mg is advisable. It's best to weigh the specimen with a jeweler’s scale. If scalp hair is unattainable, an equivalent quantity of body hair can be used. "Head hair" strictly refers to scalp hair. "Body hair" encompasses other types such as facial or axillary hair.

Process Overview

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

Accessioning is the preliminary processing of a sample into a lab’s system, which involves checking the sample's sealing and shipping integrity, generating a random LAN (Laboratory Accessioning Number), and finalizing any extra data input not covered by an electronic chain of custody mechanism.

Screening includes a preliminary assessment for illicit drugs. Although Screening is budget-friendly for excluding drug use in most cases, a confirmed screen is necessary for legal acceptability. Samples with a presumptive positive in Screening must undergo additional confirmation.

If Screening results are presumptive positive, more hair is prepped from the sample for Extraction. In Extraction, drugs are isolated from hair at a lower concentration compared to other methods (e.g., urine or saliva), making hair analysis the most challenging technique to execute.

Confirmation of positive results is done via GC/MS, GC/MS/MS, or LC/MS/MS. All samples showing presumptive positive are cleansed before confirmation as necessary. The entire test procedure from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair category and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection span: Hair drug analyses can reveal drug use for up to 90 days, compared to the shorter span of urine analyses.
• Hard to deceive: Cheating a hair test is significantly difficult, enhancing result accuracy.
• Provides use history: It demonstrates usage patterns over time, not just recent consumption.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Hair tests tend to be costlier than other testing types.
• Result variability: Factors like hair pigment and personal hair growth differences can impact drug metabolite concentrations.

Note: Commonly called "hair follicle tests", the assessment evaluates the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

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. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.

Forensic Applications and Interpretation: One of the vital objectives of hair testing is its application in forensic investigations and legal proceedings. The SoHT meeting in Verona emphasized the significance of rigorous interpretation of analytical results and the need for standardized protocols.
