Hair Follicle Drug Testing - Bellwood, LA

What it is, How it works

Hair testing emerges as an influential method for identifying drug and alcohol consumption. Hair captures a comprehensive timeline of substance use by embedding biomarkers within the fibers of its developing strands. When obtained proximally to the scalp, it offers an estimated three-month window for detecting drugs and alcohol. The collection process is easy, challenging to tamper with, and convenient for shipping.

Obtaining a 1.5-inch sample comprising roughly 200 hair strands (equivalent to the diameter of a #2 pencil) nearest to the scalp ensures a 100mg sample, which is optimal for both screening and confirmation processes. For tests such as EtG, additional screens, or those exceeding 10 panels, a 150mg sample is advised. Utilizing a jeweler’s scale for accurate measurement is suggested. In the absence of scalp hair, an equivalent amount of body hair can be used. "Head hair" refers exclusively to scalp hair, while "body hair" encompasses all other types, including facial and axillary hair.

Process Overview

The key laboratory stages for processing a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails integrating a sample into a laboratory system. This step includes ensuring the sample is properly sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any auxiliary data not captured via an electronic chain of custody system.

Screening provides an initial, rapid assessment for substances of abuse. Though cost-effective in excluding drug usage for most samples, a positive result requires confirmation for legal admissibility. Samples that test presumptively positive need subsequent confirmation.

For samples showing presumptive positivity in Screening, additional hair is extracted from the initial specimen for further processing in Extraction. In this phase, drugs are identified at a reduced concentration compared to other methods like urine or oral fluid, marking hair drug screening as particularly challenging.

Confirmation of any positive screen is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples undergo washing before confirmation if necessary. The entire testing workflow from Accessioning through Confirmation is scrutinized under both CAP (College of American Pathologists) Hair standards and ISO/IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can reveal drug use for up to 90 days, whereas urine tests detect more recent usage.
• Less prone to manipulation: Cheating on a hair drug test is extremely difficult, enhancing result accuracy.
• Offers historical insight: It portrays a drug use trend over time, not just recent consumption.

Limitations:

• Unable to detect recent use: Drugs typically aren't detectable in hair until 5-7 days post-consumption.
• Expense: Hair drug testing is generally more costly compared to other testing methods.
• Result variability: Drug metabolite levels may differ based on individual factors like hair color and growth rate.

Note: Although commonly dubbed "hair follicle tests", the analysis targets the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

When comparing hair follicle testing to traditional urine tests in Bellwood, LA, the benefits are clear. Hair tests offer superior detection accuracy, as they can identify substance use over an extended period. Additionally, the reliability of hair testing ensures that results are dependable and actionable. While urine tests are common, they often miss recent drug use, making hair testing a superior alternative for comprehensive screening.

Extended Detection Window

Hair follicle testing in Bellwood, LA provides a longer detection window of up to 90 days. This extended timeframe means employers can gain a more comprehensive understanding of an individual’s substance use history. Unlike short-term methods like urine tests, hair analysis offers insights into drug behavior over months, ensuring employers have the information needed to maintain a safe and compliant workplace.

Tamper-Resistant Testing Method

In Bellwood, LA, hair follicle tests offer a tamper-resistant testing method that reduces the risk of sample adulteration. This robustness ensures the test results are reliable and credible, eliminating doubts about manipulation. Compared to other methods, hair tests provide assurance that the results are unaltered, reinforcing trust in the testing process and its outcomes.
