Hair Follicle Drug Testing - Belfast, NC

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair retains a lengthy record of substances and alcohol use by embedding biomarkers within the strands of hair as they grow. When samples are gathered near the scalp, hair can reveal evidence of alcohol and drugs for as long as an approximately three-month period. Hair collection is straightforward, relatively resistant to tampering, and convenient to transport.

A hair sample of 1.5 inches consisting of about 200 strands (comparable to the width of a #2 pencil) closest to the scalp offers 100mg of hair, which is the optimal quantity for both screening and verification. For EtG assessments, additional tests, and/or those exceeding 10 panels, a specimen weighing 150mg is advised. Utilizing a jeweler's scale is suggested for weighing the specimen. In cases where scalp hair isn't available, an equivalent amount of body hair may be gathered. The term "head hair" specifically refers to scalp hair, while "body hair" encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory procedures that generate a drug test result are primarily divided into Accessioning, Screening, Extraction, and Confirmation.

Accessioning initiates the sample's processing into a laboratory's framework. This phase includes ensuring the sample was appropriately sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and performing any other necessary data entry not provided by a digital chain of custody system.

Screening provides an initial rapid assessment for drugs of abuse. While Screening is an economical method for disregarding drug usage for the majority of tests, positive screenings require confirmation to be legally valid. Samples that test positive during Screening necessitate secondary confirmation.

If a sample tests positive during the Screening phase, additional hair is extracted from the original specimen and prepared for Extraction. During Extraction, drugs are withdrawn from hair at a concentration much lower than other methods (e.g., urine or oral fluid), making hair drug screening the most challenging technique to perform.

Confirmation of any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive undergo a preliminary wash before confirmation as required. The entire lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair guidelines and the ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a shorter detection period.
• Resistance to deception: Cheating a hair drug test is very difficult, enhancing its result accuracy.
• Historical usage insights: It provides a record of drug use over time, not just recent usage.

Limitations:

• Unable to detect recent ingestion: Drugs become detectable in hair only after approximately 5-7 days.
• Expense: Generally, hair drug tests are pricier than alternative drug testing methods.
• Result variability: Differences such as hair color and individual hair growth rates can influence drug metabolite concentrations in hair.

Note: Although commonly called "hair follicle tests," the test evaluates the hair strand and not the scalp's hair follicle.

Why Hair Follicle Testing Beats Urine Testing

Hair testing presents several advantages over urine testing in Belfast, NC. Unlike traditional urine tests, hair follicle tests offer superior detection accuracy and reliability over an extended timeframe. Hair tests uncover long-term patterns of drug use, providing a more comprehensive picture compared to other methods.

While urine tests detect recent drug use efficiently, they fall short in revealing a complete history. For a more all-encompassing approach to identifying substance use, particularly with zero-tolerance policies, hair follicle testing is preferred.

Extended Detection Window

One of the primary advantages of hair follicle testing in Belfast, NC is its extended detection window. Able to identify substances used up to 90 days prior, this method provides employers with a long-term view of an individual's drug history.

This comprehensive insight is invaluable for assessing an applicant's or employee's past behaviors, offering assurance in drug-free policy adherence and providing a basis for informed decision-making.

Tamper-Resistant Testing Method

The robust nature of hair follicle testing in Belfast, NC minimizes the chance of tampering, ensuring the reliability of results. Unlike methods that can be more easily manipulated, hair samples are less susceptible to adulteration.

This method offers an impenetrable measure of drug use, maintaining the integrity of the testing process and the trust of those who depend on accurate and authentic results.
