Hair Follicle Drug Testing - National, MD

What it is, How it works

Hair assessments have emerged as an influential means for identifying drug and alcohol consumption. Hair retains a comprehensive history by capturing biomarkers within the fibers of its growing strand. When sourced near the scalp, it can offer a detection period of up to around 3 months for alcohol and drugs. Hair collection is straightforward, comparatively tamper-proof, and easily transportable.

A 1.5-inch segment containing around 200 hair strands (approximately equivalent to the size of a #2 pencil) adjacent to the scalp yields 100mg, the optimal quantity for screening and confirmation. For EtG, additional markers, and/or analyses exceeding 10 panels, a 150mg specimen is suggested. We recommend measuring the sample on a jeweler’s scale. If scalp hair is not an option, a comparable amount of body hair is acceptable. "Head hair" specifically pertains to scalp hair. "Body hair" includes all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result involves four major steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning covers the initial integration of a sample into a lab’s system. This step includes verifying the sample's proper sealing and shipment, generating a random LAN (Laboratory Accessioning Number), and filling in any additional details not covered by an electronic chain of custody system.

Screening offers an initial rapid appraisal for drugs of abuse. Though Screening is cost-efficient for dismissing drug use in most samples, a positive result must be verified for legal admissibility. Samples testing positive in Screening entail a secondary confirmation.

Should a sample return a positive result during Screening, additional hair is extracted from the primary specimen and readied for Extraction. Drugs in the hair are extracted at significantly lower concentrations than those in other methodologies (e.g., urine or oral fluid), making hair drug assessments the most complex to execute.

Positive results from Screening undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples are cleansed before confirmation as necessary. The full lab procedure from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extensive detection frame: Hair drug checks can discover drug usage for up to 90 days, unlike urine tests which offer a reduced detection timeline.
• High resistance to manipulation: Cheating a hair drug test is notably challenging, lending greater accuracy to the results.
• Historical tracking capability: This can reveal a drug use pattern over time, beyond mere recent consumption.

Limitations:

• Incapacity for recent detection: A period of about 5-7 days is required for drugs to manifest in hair.
• Expense: Hair drug assessments generally bear higher costs than alternate methods.
• Result variability: Elements like hair color and personal hair growth differences can impact the drug metabolite concentration within the hair.

Note: Frequently termed "hair follicle tests", the analysis genuinely examines the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing stands out in National, MD by trumping traditional urine tests for several reasons. Primarily, hair tests offer superior detection accuracy and reliability. While urine tests can only trace recent usage, hair tests can detect drug use over a longer timeframe, ensuring a comprehensive understanding of an individual's substance use history. This makes them a preferred choice in many professional settings.

Extended Detection Window

In National, MD, hair follicle testing offers a distinct advantage with its extended detection window. This method can reveal drug use spanning up to 90 days, providing employers with an in-depth view of an employee's or candidate’s substance use history. Such a comprehensive assessment is invaluable when making informed employment decisions, contributing to safer workplace environments.

Tamper-Resistant Testing Method

Hair follicle tests in National, MD drastically reduce the potential for sample tampering. Unlike urine tests, which can sometimes fall victim to sample adulteration, hair tests ensure reliability by their very nature. This integrity in results provides assurance and confidence both to administrators and those subject to the testing process, solidifying the reputation of hair testing as highly dependable.

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.
