Hair Follicle Drug Testing - Fort Indiantown Gap, PA

What it is, How it works

Hair testing is recognized as an effective means for uncovering drug and alcohol usage. It reflects a prolonged history of substance involvement by embedding biomarkers in the strands of emerging hair. When hair is sourced from near the scalp, it can offer a detection time frame of up to three months for drugs and alcohol. Collecting hair is straightforward, altering it is challenging, and it is conveniently shipped.

A hair sample measuring 1.5 inches, consisting of around 200 strands (approximately the size of a #2 pencil) near the scalp, yields 100mg of hair, which is optimal for analysis and verification. For EtG, additional substances, and tests exceeding 10 panels, it is advised to use 150mg of the sample. It is suggested to weigh the sample using a jeweler’s scale. In cases where scalp hair cannot be obtained, a similar quantity of body hair can be used. The term ‘head hair’ specifically denotes scalp hair, while ‘body hair’ encompasses other types (facial, axillary, etc.).

Process Outline

There are four primary stages in the laboratory processing of drug test samples: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves enrolling a sample into the laboratory’s system initially. This step ensures the sample is sealed and dispatched correctly, associates it with a random LAN (Laboratory Accessioning Number), and supplements any missing data from an electronic record management system.

Screening includes an initial rapid assessment for substances of abuse. Although Screening is a cost-efficient method for dismissing drug use in most samples, a positive outcome requires verification before being accepted in legal settings. Samples with presumptive positive results in Screening need subsequent confirmation.

When a sample shows presumptive positivity during Screening, additional hair is extracted from the original sample and prepared for Extraction. At this phase, drugs are isolated from hair at significantly lower concentrations compared to other methods (e.g., urine or saliva), rendering hair drug screening as the most complex procedure.

Positive results from screening are confirmed utilizing GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive outcomes undergo washing before confirmation if necessary. The complete laboratory workflow from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation standards.

Benefits of hair drug testing:

• Extended detection span: Hair drug evaluations can reveal drug use for as long as 90 days, whereas urine evaluations have a briefer detection span.
• Challenging to circumvent: Cheating a hair drug evaluation is notably difficult, thus enhancing result accuracy.
• Delivers historical insight: It furnishes a record of drug use over a duration, not merely recent use.

Drawbacks:

• Incapable of detecting recent use: There’s a delay of 5-7 days before drugs can be identified in hair.
• Expense: Hair drug evaluations tend to be more costly compared to other drug evaluation methods.
• Result variability: Elements such as hair hue and personal differences in hair growth can impact metabolite concentration within hair.

Note: Though termed “hair follicle tests”, the analysis targets the hair strand itself, 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.

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.
