Hair Follicle Drug Testing - Milford, VA

What it is, How it works

Hair analysis has emerged as an effective means for identifying alcohol and drug usage. Hair retains a prolonged record of these substances by encapsulating biomarkers within the fibers of the growing strand. When collected near the scalp, it can offer a detection window of up to nearly 3 months for alcohol and drugs. The collection process for hair is straightforward, relatively tamper-resistant, and easily shippable.

A sample measuring 1.5 inches, consisting of around 200 hairs (roughly pencil-sized in diameter), nearest the scalp will yield approximately 100mg of hair—a quintessential specimen for both screening and confirmation. For EtG, additional tests, or evaluations exceeding 10 panels, it is advisable to gather 150mg of the sample. Utilize a jeweler’s scale for precise measurement. In the absence of scalp hair, an equivalent quantity of body hair is acceptable. By head hair, we refer specifically to scalp hair. Body hair denotes all other forms, including facial and axillary.

Process Overview

The laboratory procedure for processing a drug test result incorporates four principal stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning signifies the preliminary sample processing within a lab’s system. This process entails assuring proper sealing and shipment of the sample, attributing a unique LAN (Laboratory Accessioning Number), and completing any requisite data input absent from an electronic chain of custody system.

Screening constitutes a preliminary drug check. Although an economical approach for excluding drug use across most samples, a positive outcome requires validation for legal acceptability. Presumptively positive samples from Screening necessitate secondary confirmation.

Should the Screening phase yield a presumptive positive, additional hair is extracted from the original specimen for further Extraction. Within this phase, drugs are isolated from hair at a considerably lower concentration in contrast to other methods (e.g., urine or oral fluid), rendering hair testing a challenging methodology to execute.

Subsequent to a positive Screening result, confirmation is undertaken through GC/MS, GC/MS/MS, or LC/MS/MS. Samples deemed presumptively positive undergo requisite washing prior to confirmation. The complete laboratory process, from Accessioning to Confirmation, is scrutinized under CAP (College of American Pathologists) Hair designation and complies with ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extensive detection period: Hair drug examinations can identify usage for as long as 90 days, unlike urine tests with a shorter timeframe.
• Hard to falsify: Hair drug tests are inherently sophisticated to manipulate, ensuring more valid results.
• Shows usage trends: It can delineate a timeline of drug consumption, not merely recent occurrences.

Limitations:

• Incapable of identifying recent intake: Drugs require roughly 5-7 days to manifest in hair.
• Expense: Hair drug evaluations are typically pricier than alternative methods.
• Result variability: Influences like hair color or autonomic growth differences can impact drug metabolite levels in hair.

Note: Although commonly termed as "hair follicle tests", the analysis focuses on the hair strand itself, not the follicles beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing in Milford, VA outshines urine testing due to its superior detection accuracy and reliability. Unlike urine tests that detect recent drug use, hair testing captures a longer drug use history, offering a deeper insight into an individual's substance use.

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.
