Hair Follicle Drug Testing - West Canton, NC

What it is, How it works

The utilization of hair testing has gained recognition as an effective means for identifying drug and alcohol consumption. Hair offers a timeline of substance use by capturing biomarkers within the strands as they grow. When hair is sampled near the scalp, it can detect the presence of alcohol and drugs for about three months. Hair collection is straightforward, challenging to tamper with, and simple to transport.

An optimal sample comprises a 1.5-inch segment with approximately 200 hair strands (roughly equivalent to a #2 pencil in thickness) near the scalp, yielding 100mg, suitable for initial and confirmatory testing. For tests such as EtG, add-ons, and those exceeding 10 panels, a specimen of 150mg is advised. We suggest using a jeweler’s scale for accuracy in measuring the specimen. If scalp hair isn't available, a comparable quantity of body hair can be used. The term "head hair" refers strictly to scalp hair, while "body hair" encompasses all other types (facial, axillary, etc.).

Process Overview

The processing of a drug test result in a laboratory encompasses four main stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the preliminary processing of a sample into the laboratory's system, which includes confirming the proper sealing and shipment of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data input not captured by an electronic chain of custody framework.

Screening serves as an initial rapid assessment for drugs of abuse. Although Screening is an economical method to exclude drug usage in most samples, a positive result must be substantiated to be used in legal contexts. Samples that yield a presumptively positive result in Screening require further confirmation.

Should a sample display a presumptive positive in the Screening phase, additional hair is extracted from the original specimen and prepared for Extraction. In this stage, substances are drawn out from hair at a significantly lower concentration compared to other methods (e.g., urine or oral fluid), which is why hair drug testing is considered one of the most complex methodologies.

Confirmation of any positive screening outcome is achieved using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples undergo washing before confirmation if necessary. The full laboratory procedure from Accessioning to Confirmation is under the review of both the CAP (College of American Pathologists) Hair designation and maintained according to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug consumption for up to 90 days, unlike urine tests which have a shorter timeframe.
• Hard to manipulate: Successfully cheating a hair drug test is very challenging, ensuring higher accuracy of results.
• Offers historical insight: It can illustrate a pattern of drug use over time, not merely recent intake.

Limitations:

• Cannot detect recent intake: Drugs become traceable in hair only after about 5-7 days.
• Expense: Hair drug tests generally cost more than other testing methods.
• Result variability: Factors like hair color and individual hair growth differences can influence drug metabolite concentration in hair.

Note: Although commonly termed "hair follicle tests", the analysis actually focuses on the hair strand rather than the follicle below the scalp.

Why Hair Follicle Testing Beats Urine Testing

When comparing hair follicle testing to traditional urine tests in West Canton, NC, it's clear why the former is often preferred.

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.
