Hair Follicle Drug Testing - Roman Forest, TX

What it is, How it works

Hair analysis has emerged as a significant method for identifying drug and alcohol consumption. The strands hold a long-term record of these substances by embedding biomarkers within the fibers as the hair grows. When collected near the scalp, it offers a detection period of up to three months for alcohol and drugs. This method is straightforward to collect, challenging to tamper with, and is efficient to transport.

A 1.5-inch sample, comprising about 200 hair strands (comparable to the thickness of a number two pencil), proximate to the scalp provides 100mg of hair, meeting the ideal requirements for both screening and confirmation. For EtG, additional testing, and tests exceeding 10 panels, 150mg of sample is advised. It is suggested to weigh the sample using a jeweler's scale. Should scalp hair be not accessible, a proportionate amount of body hair can be utilized. References to head hair specify scalp hair alone. Body hair encompasses all other types such as facial and axillary hair.

Process Overview

The laboratory process for processing a drug test involves four main phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the preliminary processing of a sample within a lab’s system. This phase ensures the sample was sealed and dispatched correctly, assigns a random LAN (Laboratory Accessioning Number), and completes additional data entry if not handled by an electronic chain of custody system.

Screening entails an initial rapid assessment for drugs of abuse. Although Screening is a cost-efficient strategy for excluding drug use in the majority of samples, any positive result needs confirmation for legal admissibility. Samples presenting a presumptive positive in Screening necessitate a secondary confirmation.

In instances where a sample is deemed presumptively positive during Screening, additional hair is extracted from the initial sample and readied for Extraction. During this procedure, drugs are extracted from hair in significantly lower concentrations compared to alternative methods (e.g., urine or oral fluid), attributing to the complexity of hair drug screening.

Confirmation of positive screening outcomes utilizes GC/MS, GC/MS/MS, or LC/MS/MS technology. Before confirmation, all presumptive positive samples are washed as required. The comprehensive lab process from Accessioning through Confirmation is scrutinized under the CAP (College of American Pathologists) Hair standard and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can trace drug use the past 90 days, unlike urine tests with shorter detection periods.
• Hard to falsify: Cheating a hair drug test is extremely challenging, resulting in more accurate outcomes.
• Offers historical insight: It can reveal drug use patterns over time, beyond just recent consumption.

Limitations:

• Incapability to detect recent use: Drugs become detectable in hair after about 5-7 days.
• Expense: Hair drug tests typically cost more than other testing methods.
• Result variability: Elements like hair color and personal hair growth rates can influence drug metabolite concentration in hair.

Note: Though often labeled as "hair follicle tests", the analysis is performed on the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why choose hair follicle testing over urine examination in Roman Forest, TX? Hair tests deliver enhanced detection accuracy and reliability. While urine tests might only reveal recent drug use, hair tests provide a broader substance history. They capture a 90-day period, serving as a more comprehensive analysis tool.

Additionally, hair tests deter potential manipulation. Unlike urine samples, which require stringent handling to prevent tampering, hair samples are resilient to adulteration, securing a higher confidence level in the outcomes.

Extended Detection Window

A standout benefit of hair follicle testing in Roman Forest, TX, is its extended detection window. Employers receive an encompassing view of an individual's drug use history, up to 90 days, allowing for informed decision-making. This window offers greater assurance of an applicant or employee's compliance with drug-free workplace policies.

This prolonged detection timeline aids businesses in establishing consistent practices and expectations, reinforcing workplace safety through comprehensive screening methods.

Tamper-Resistant Testing Method

In Roman Forest, TX, hair follicle testing substantially minimizes tampering risks, providing credible outcomes. Samples derived from hair are difficult to adulterate, offering a higher level of trust than easily manipulated urine samples. This effectively deters dishonest practices during drug testing, enhancing the test's integrity.

This method's robustness ensures the reliability of results, giving employers peace of mind knowing that their testing processes are secure and trustworthy.
