Hair Follicle Drug Testing - Glenmont, MD

What it is, How it works

Hair analysis is increasingly recognized as a robust method for detecting drug and alcohol consumption. It offers a retrospective view of substance use by capturing indicators within the hair's growing strands. Sampling hair close to the scalp can yield detection results for up to roughly three months for alcohol and drug use. Collection is straightforward, challenging to alter, and convenient to transport.

A sample measuring 1.5 inches and comprising about 200 hair strands (approximately the width of a #2 pencil) taken nearest to the scalp provides 100mg of hair, which is optimal for testing and validation. For tests involving EtG, additional categories, and/or more than 10 panels, it's advisable to gather 150mg of the sample with precision using a jeweler’s scale. If scalp hair is not an option, a comparable quantity of body hair is suitable. Our references to head hair specifically denote scalp hair. On the other hand, body hair encompasses all other hair types (such as facial and axillary hair).

Process Overview

The laboratory processing of a drug test outcome is segmented into four principal steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial integration of a specimen into the lab system. This step involves confirming the sample's seal and shipment status, generating a LAN (Laboratory Accessioning Number), and finalizing any additional data recording tasks that an electronic chain of custody system might not have already covered.

During Screening, a preliminary assessment is conducted for potential drug use. Although Screening offers a cost-effective approach to ruling out drug use across most samples, any positive finding necessitates confirmation to be valid within legal settings. Consequently, samples yielding positive in Screening undergo obligatory secondary validation.

Should a sample test positive in Screening, extra hair is extracted from the initial collection for the Extraction stage. Here, drugs are isolated from the hair in much lower concentrations than those found in other testing modalities (e.g., urine or oral fluid), making hair analysis the most complex to execute.

Confirmation for any positive findings in Screening is carried out using methods such as GC/MS, GC/MS/MS or LC/MS/MS. Suspected positive samples are cleaned prior to final confirmation as required. The full laboratory workflow from Accessioning to Confirmation is scrutinized following CAP (College of American Pathologists) Hair standards and holds accreditation to ISO / IEC 17025 norms.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug usage for up to 90 days, offering a longer evaluation window than urine tests.
• Secure against tampering: Cheating a hair drug test is notably challenging, enhancing result reliability.
• Provides temporal usage patterns: It reflects drug use patterns over time, rather than just recent use.

Limitations:

• Incapable of detecting new use: Drugs require around 5-7 days post-use to appear in hair samples.
• Expense: Hair tests tend to be pricier relative to other testing techniques.
• Result variability: Aspects such as hair color and personal hair growth differences can influence metabolite concentration in hair.

Note: The term "hair follicle tests" is frequently used, but the procedure analyzes the hair strand itself and 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.
