Hair Follicle Drug Testing - Iron Station, NC

What it is, How it works

Hair analysis has gained recognition as an effective method for identifying drug and alcohol consumption. The hair fiber traps biomarkers indicative of alcohol and substances, offering a long-term consumption record. When taken from the scalp, hair can reflect drug and alcohol intake over a period of up to three months. Collection of hair samples is straightforward, challenging to tamper with, and convenient to transport.

Obtaining a 1.5-inch section of approximately 200 hair strands (about the thickness of a #2 pencil) closest to the scalp yields about 100mg of hair, ideal for initial and confirmatory testing. For EtG, additional tests, or those exceeding ten panels, a 150mg sample is advisable. Using a jeweler’s scale to weigh the sample is encouraged. Should scalp hair not be available, an equivalent amount of body hair may be used instead. The term "head hair" refers specifically to scalp hair, whereas "body hair" comprises all other types (e.g., facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result consists of four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary step of integrating a sample into a laboratory’s workflow. This step includes ensuring the sample is sealed and shipped correctly, assigning a unique LAN (Laboratory Accessioning Number), and completing any necessary data input not covered by an electronic chain of custody.

Screening carries out an initial, rapid assessment for drug misuse. Although Screening provides a cost-efficient means of excluding drug use in the majority of samples, results that yield tentative positive outcomes require confirmation for legal acceptability. All samples marked as potentially positive in Screening undergo further confirmation.

A sample showing a potential positive in the Screening stage will have additional hair extracted from the original sample for the Extraction phase. Drugs are isolated from hair at significantly lower concentrations compared to other testing methods (like urine or saliva), underscoring why hair drug tests pose the greatest methodological challenge.

Confirmation of any tentative positive Screening outcomes relies on GC/MS, GC/MS/MS, or LC/MS/MS techniques. All suspected positive samples are cleansed before confirmation as necessary. The complete lab process, from Accessioning to Confirmation, is thoroughly audited under the CAP (College of American Pathologists) Hair guidelines and certified according to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection range: Hair drug testing can reveal drug use history up to 90 days back, unlike urine tests with a shorter detection range.
• Resistant to manipulation: Cheating a hair drug test is exceedingly difficult, thus enhancing accuracy.
• Historical drug usage insight: This method provides a timeline of drug consumption rather than merely recent usage.

Limitations:

• Delayed detection for recent usage: Drugs require roughly 5-7 days to be identified in hair samples.
• Expense: Hair drug assessments tend to be more costly compared to alternative methods.
• Result discrepancies: Variables such as hair color and personal differences in hair growth can influence drug metabolite concentration in hair.

Note: Although commonly called "hair follicle tests", the evaluation pertains to the hair strand itself, not the underlying follicle within the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Iron Station, NC, hair follicle testing has shown itself superior to traditional urine tests. Why? The detection accuracy is greatly enhanced as hair tests screen for traces of drug use over longer durations. Moreover, the reliability of hair testing means fewer chances of error. As a result, hair drug tests deliver benefits that significantly outstrip those of urine tests.

Extended Detection Window

One of the key advantages of hair follicle testing in Iron Station, NC, is its extended detection window. Capable of identifying drug use over a span of up to 90 days, it provides a complete view of an individual's substance use history. For employers, this long-term detection capability means a deeper insight into employee behavior, promoting informed hiring and policy decisions.

Tamper-Resistant Testing Method

Hair follicle testing in Iron Station, NC, sets a benchmark in tamper resistance. The testing procedure ensures that the sample remains unchanged and authentic, significantly cutting down the risk of sample adulteration. This reliability builds trust and provides results that are hard to dispute, thereby eliminating uncertainties in the drug screening process.

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.
