Hair Follicle Drug Testing - Roanoke Rapids, NC

What it is, How it works

Hair analysis has become recognized as an effective means for detecting drug and alcohol consumption. Hair offers a comprehensive timeline of alcohol and drug exposure by capturing biomarkers in the strands as they grow. When sampled near the scalp, hair can offer a detection period of up to around three months for substances. Collecting hair is straightforward, somewhat resistant to tampering, and convenient to send.

A sample measuring 1.5 inches comprising roughly 200 strands (comparable to the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, which is considered the optimal amount for assessment and verification. For EtG, enhancements, and/or evaluations exceeding 10 panels, it is advisable to use 150mg of the sample. We suggest utilizing a jeweler’s scale for weighing the sample. In the absence of scalp hair, a comparable quantity of body hair may be used. Specifically, "head hair" pertains solely to scalp strands, while "body hair" includes all other types (facial, axillary, etc.).

Process Overview

The primary phases in the lab processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves integrating a sample into the laboratory’s system initially. This step includes confirming that the sample was sealed and dispatched correctly, generating a random LAN (Laboratory Accessioning Number), and completing any additional data input missing from an electronic chain of custody system.

Screening encompasses a preliminary rapid assessment for substances of abuse. While Screening is an economical approach to dismiss drug use in most samples, a positive result requires confirmation for legal validity. Samples that test as potentially positive in Screening require further confirmation.

If a sample shows potential positivity during Screening, more hair is taken from the original sample and prepped for Extraction. Here, drugs are extracted from hair at concentrations much lower than other techniques (e.g., urine or oral fluid), making hair drug screening a particularly challenging method to perform.

Confirmation of any positive Screening outcome is carried out using GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation if necessary. The comprehensive lab process from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use up to 90 days, unlike urine tests, which have a reduced detection timeframe.
• Resistance to tampering: It is quite challenging to manipulate hair drug test results, thus enhancing accuracy.
• Data over time: It provides a record of drug use behavior over a timeframe, not only recent consumption.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Hair drug tests tend to be costlier than alternative drug testing methods.
• Result variability: Factors including hair color and personal hair growth differences may influence drug metabolite levels in the hair.

Note: Commonly termed "hair follicle tests", the analysis actually assesses the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Roanoke Rapids, NC, hair follicle testing stands out compared to traditional urine tests. The ability to detect drug usage comprehensively sets it apart. Hair tests are less prone to manipulation, offering a significant advantage for those with zero-tolerance policies.

Hair follicle tests outshine urine tests with their superior detection accuracy. While urine tests may identify recent drug use, the extended detection window of hair tests offers more reliable insights into a person's substance history.

Extended Detection Window

In Roanoke Rapids, NC, hair follicle testing extends the drug detection window, providing a comprehensive overview of substance use up to 90 days. This prolonged period allows employers to better understand patterns in an applicant's or employee's drug history.

Compared to other methods, the extended reach of hair tests offers substantial benefits. Informed hiring and monitoring decisions become possible, drawing from a detailed temporal perspective on 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.
