Hair Follicle Drug Testing - Evansville, WI

What it is, How it works

Hair testing is increasingly recognized as a vital method for identifying drug and alcohol usage. It offers an extended historical view of substance use by capturing biomarkers within the fibers of the hair strand as it grows. When hair is taken from near the scalp, it can reveal up to a roughly 3-month detection period for alcohol and drugs. Collection is straightforward, difficult to tamper with, and easy to transport.

A typical sample involves a 1.5-inch section of approximately 200 hairs (similar in diameter to a #2 pencil) from close to the scalp to yield 100mg, the perfect amount for both screening and verification. For EtG, additional tests, or panels exceeding 10, 150mg of hair is advisable. We suggest weighing samples with a jeweler's scale. If scalp hair is unavailable, an amount of body hair equivalent to the scalp sample size may be collected. "Head hair" specifically refers to scalp hair, while "body hair" includes all other types (e.g., facial, axillary).

Process Overview

The laboratory handling of drug tests involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is where a sample is first processed into a lab's system, ensuring it was sealed and delivered correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any data entry not covered by electronic chain of custody systems.

Screening conducts an initial examination for drugs of abuse. This step is cost-effective for ruling out drug use in most samples; however, legal admissibility requires that a positive screen be confirmed. Samples testing positive in Screening necessitate additional confirmation.

For samples testing positive in Screening, further hair is taken from the original sample for Extraction. During this phase, drugs are extracted at a lower concentration than with other methods (e.g., urine or oral fluid), contributing to the complexity of hair drug testing.

Positive Screening results undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples receive washing before Confirmation as necessary. The entire process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Hair tests can trace drug use over approximately 90 days, unlike urine tests with more restricted detection timeframes.
• Hard to manipulate: Hair drug tests are tricky to deceive, thus ensuring more accurate outcomes.
• Historical overview: Such tests can illustrate drug-use trends rather than just immediate use.

Limitations:

• Incapable of identifying recent use: It requires about 5-7 days for drugs to register in hair samples.
• Expense: Hair drug tests typically cost more than alternative drug test methods.
• Result variability: Differences like hair color and personal hair growth rates can influence drug metabolite levels in hair.

Note: Despite being called "hair follicle tests," the analysis focuses on the hair strand itself and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Evansville, WI, there's a reason why hair follicle testing stands out compared to the traditional urine test. Its ability to accurately detect drug use is unparalleled, offering a longer detection period that is beneficial in various circumstances. While urine tests are standard, they often fall short in terms of the detection window and reliability of the results, making hair testing the superior choice for many testing purposes.

Hair follicle tests shine with their accurate detection capabilities over an extended timeframe, unlike urine tests which can only reveal recent drug use. Moreover, the collection of hair samples is less invasive and reduces the chances of sample adulteration. In an era where precision is key, hair follicle tests provide a robust solution that meets the needs of employers, legal systems, and individuals seeking comprehensive substance use insights.

Extended Detection Window

The extended detection window of hair follicle tests in Evansville, WI is a game-changer. Unlike other methods, hair analysis can monitor substance use for up to 90 days, offering employers and partners a deeper insight into an individual's history. This extended timeframe captures long-term patterns of use, providing a thorough profile that is invaluable in making informed employment or legal decisions.

Given the broader timeframe, hair follicle testing is especially effective for organizations keen on maintaining a drug-free environment. The process of analyzing hair is meticulous, capable of unveiling past usage that traditional tests, like urine screens, might overlook. This robust detection range serves as a critical tool for companies enforcing strict policies and for courts in need of reliable substance use records.

Tamper-Resistant Testing Method

Hair follicle tests are fundamentally designed to combat sample tampering in Evansville, WI. Their methodology makes it extremely difficult for individuals to alter results, compared to other test types. The samples are collected in an observed setting, ensuring that results are reliable and unbiased, reflecting the true substance use of the individual being tested.

Incorporating a tamper-resistant testing method like hair analysis increases the credibility of the results. For employers, legal agencies, and treatment professionals, this reliability is essential in maintaining trust in the system and ensuring that any outcomes or actions based on these results are fair and factual.
