Hair Follicle Drug Testing - Kieler, WI

What it is, How it works

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair strands capture indicators within the fibers as they grow, offering an extended chronology of alcohol and drug presence. When snipped near the roots, hair can reveal drug and alcohol exposure over a span of roughly three months. Hair collection is straightforward, relatively hard to tamper with, and convenient for shipping.

A hair sample measuring 1.5 inches, consisting of approximately 200 strands (equivalent to the thickness of a #2 pencil) nearest to the scalp, yields 100mg, which is ideal for both screening and confirmation purposes. For EtG or additional tests exceeding 10 panels, a specimen of 150mg is optimal. Using a jeweler’s scale to weigh the specimen is suggested. In the absence of scalp hair, a similar quantity of body hair may be utilized. The term head hair exclusively denotes scalp hair. Body hair encompasses all other varieties (facial, axillary, etc.).

Process Overview

The laboratory evaluation of drug test results encompasses four key phases: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a specimen is initially processed into the laboratory database. This step includes confirming the sample’s proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any outstanding data entry that an electronic chain of custody system might not cover.

Screening conducts a swift preliminary examination for substances commonly abused. While Screening serves as a cost-efficient method to discount drug use in a majority of cases, a positive result necessitates validation to be legally acceptable. Samples with presumptive positivity during Screening require further verification.

Upon identifying a presumptive positive in the Screening stage, additional hair is extracted from the original sample for the Extraction process. This involves isolating drugs at a significantly lower concentration from hair compared to other methods (such as urine or oral samples), highlighting why hair drug testing remains one of the most challenging techniques.

Verification of any positive results during Screening is achieved via GC/MS, GC/MS/MS, or LC/MS/MS methodologies. Before verification, each presumptive positive sample undergoes necessary washing. The complete laboratory procedure, from Accessioning to Confirmation, undergoes review under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug use up to 90 days, unlike urine tests with their limited detection timeframe.
• Hard to falsify: Cheating a hair drug test is highly challenging, enhancing the reliability of the results.
• Offers historical insight: It can reflect a pattern of substance intake over time, beyond just recent events.

Limitations:

• Lacks capability to detect recent use: Drugs become detectable in hair after a period of approximately 5-7 days.
• Expense: Hair drug tests tend to be pricier compared to other methods.
• Result variability: Elements like hair color and individual hair growth differences may influence the drug metabolite levels observed in the hair.

Note: Commonly termed "hair follicle tests," these analyses focus on the hair strand itself and not the follicle beneath the skin.

Why Hair Follicle Testing Beats Urine Testing

In Kieler, WI, hair follicle testing surpasses urine testing in several ways. It offers superior detection accuracy and reliability, capturing drug use over a more extended period. Detecting substances for up to 90 days, hair tests provide a more comprehensive look than traditional urine tests, which are limited to short-term detection windows.

Hair tests are nearly impossible to tamper with, unlike urine tests which can be easily adulterated. This ensures the integrity of the results. Employers and authorities favour hair tests because they reliably track consistent drug use patterns over an extended timeframe.

Extended Detection Window

Hair follicle testing in Kieler, WI, offers an extended detection window of up to 90 days. This capability provides employers with a detailed understanding of a candidate or employee's drug-use history, far surpassing the scope of other testing methods.

Employers benefit from this in-depth view, enabling more informed hiring and retention decisions. With a 90-day history, the probability of overlooking past substance abuse declines significantly, promoting a safer workplace environment.

Tamper-Resistant Testing Method

The tamper-resistant nature of hair follicle tests in Kieler, WI, enhances their reliability for drug screening. These tests minimize the risk of sample adulteration due to the complex and secure collection process.

Hair tests provide undeniable results, as the substance deposits remain within the hair strand. This feature reduces the chance of falsified or altered outcomes, offering assurance to employers and legal entities regarding the credibility of the results.
