Hair Follicle Drug Testing - Whitehall, MI

What it is, How it works

Hair testing is now considered a significant instrument for identifying drug and alcohol consumption. Hair offers a prolonged history of alcohol and other substances by encapsulating biomarkers within the strands as hair grows. When sourced near the scalp, hair can offer a detection period of up to around 3 months for alcohol and other substances. Hair collection is easy, relatively tamper-resistant, and convenient to transport.

A hair sample measuring 1.5 inches long, consisting of roughly 200 strands (similar to the thickness of a #2 pencil) nearest to the scalp provides 100mg of hair, which is the optimal quantity for screening and verification. For EtG, supplemental tests, and/or analyses beyond 10 panels, a specimen weight of 150mg is suggested. Utilizing a jeweler's scale is advised for weighing the sample. If scalp hair is unobtainable, a comparable amount of body hair may be used. References to head hair imply scalp hair solely. Body hair encompasses all other forms of hair (facial, axillary, etc.).

Process Overview

The primary stages in the laboratory handling of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning consists of the initial procedure to integrate a sample into a lab’s system. This step includes ensuring the sample’s proper sealing and shipping, allocating a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry absent from an electronic chain of custody system.

Screening performs an initial swift evaluation for drugs of abuse. While Screening is a cost-efficient method to eliminate drug use in most samples, a positive screen necessitates validation for court admissibility. Samples that test presumptively positive during Screening must undergo a further confirmation.

When a sample tests presumptively positive in the Screening stage, additional hair is taken from the original sample and prepped for Extraction. During this phase, drugs are extracted from hair at a much lower concentration than in other methods (ex. urine or oral fluid), which is a reason hair drug screening is a more intricate method to conduct.

Confirmation of any positive screening outcome occurs through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation if necessary. The complete laboratory process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can identify drug use for up to 90 days, unlike urine tests with shorter detection periods.
• Difficulty to cheat: It's quite challenging to deceive a hair drug test, ensuring more precise results.
• Provides historical data: The test can reveal a pattern of drug use over time, rather than indicating only recent usage.

Limitations:

• Cannot detect recent use: It requires about 5-7 days for drugs to become detectable in hair.
• Cost: Hair drug tests are typically pricier than other drug testing approaches.
• Variations in results: Hair color and personal differences in hair growth can influence drug metabolite levels in the hair.

Note: Though commonly termed as "hair follicle tests", the analysis actually reviews the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why is hair follicle testing superior to urine tests in Whitehall, MI? It's all about better detection and reliability. Hair tests boast extensive detection windows, capturing a broader drug use history. Additionally, the accuracy of hair sampling significantly diminishes the likelihood of false negatives, setting it apart from more traditional testing methods like urine analysis.

Extended Detection Window

In Whitehall, MI, the extended detection window of hair follicle testing is a key advantage. Unlike other methods, it identifies drug use up to 90 days prior, offering a comprehensive insight into an individual's substance history. This extended window can be critical for employers aiming to maintain a safe and productive work environment by understanding long-term drug habits.

Tamper-Resistant Testing Method

Hair follicle tests are known in Whitehall, MI for their almost tamper-proof nature. This reduces the risk of sample manipulation or dilution that may occur with other types of testing, such as urine tests. As a result, hair testing presents reliable and unquestionable results, ensuring the integrity of the testing process and enhancing trust in outcomes.

Convenient Nationwide Locations

With numerous testing centers available nationwide, including in Whitehall, MI, accessing hair follicle testing couldn't be more convenient. The readily accessible locations ensure a seamless and stress-free testing experience for individuals and employers alike.
