Hair Follicle Drug Testing - Darden, TN

What it is, How it works

Testing hair is recognized as an effective method for identifying alcohol and drug consumption. Hair serves as a record of extended substance use by embedding biomarkers within the fibers of the hair as it grows. Hair samples taken near the scalp can reveal drug and alcohol consumption for up to around 3 months. Collecting hair is straightforward, tampering with it is challenging, and it is convenient to transport.

To conduct an accurate evaluation, a 1.5-inch segment consisting of roughly 200 strands (similar in thickness to a #2 pencil) provides 100mg of hair, ideal for both screening and confirmation processes. For assessments such as EtG, add-ons, or panels exceeding 10, 150mg is suggested. We advise using a jeweler’s scale to measure the specimen. Should scalp hair be unavailable, an equivalent amount of body hair is suitable. Head hair strictly denotes scalp hair, whereas body hair includes other types (like facial or axillary hair).

Process Overview

The lab processing of a drug test comprises four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the first stage, involving the integration of a specimen into a lab system. This phase pertains to ensuring the sample's proper seal and delivery, assigning a random Laboratory Accessioning Number (LAN), and completing any supplementary data entries absent from an electronic chain of custody.

Screening represents an initial, expedited assessment for substance abuse. Though Screening efficiently excludes drug usage for most samples, a positive screen must undergo confirmation to be court-admissible. Presumptively positive samples from Screening necessitate further confirmation.

For samples indicating presumed positivity during Screening, additional hair from the initial sample undergoes preparation for Extraction. In this phase, drugs are derived from hair at significantly reduced concentrations compared to methods like urine or oral fluid, highlighting the complexity of hair drug screening.

To confirm any positive results from screening, analysis is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are cleaned before proceeding to confirmation when necessary. The full process from Accessioning to Confirmation is scrutinized under both the CAP Hair designation and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests detect substance usage for up to 90 days, while urine tests have a narrower detection range.
• Hard to falsify: Hair drug tests are challenging to manipulate, ensuring more accurate outcomes.
• Historical insight: It's equipped to outline a history of drug usage over time, beyond immediate use.

Limitations:

• Inability to detect recent use: Drugs are traceable in hair only after 5-7 days.
• Expense: Hair testing is generally costlier than alternative methods.
• Result variability: Hair color and personal hair growth rates might influence metabolite concentrations.

Note: Tests often mislabeled as "hair follicle tests" actually examine the hair strand itself, excluding the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Darden, TN, hair follicle testing stands out as the preferred option over standard urine tests due to its superior detection capabilities. While urine tests may only identify recent drug use, hair tests offer a broader detection window. This allows for a more comprehensive understanding of a person's substance history, ensuring higher accuracy and reliability for stakeholders.

Hair testing provides benefits in workplaces with zero-tolerance policies. In comparison, urine tests can be manipulated more easily, and their shorter detection window might miss ongoing substance use. The precision of hair testing in revealing patterns of use over an extended timeframe makes it a more dependable choice for employers and legal entities alike.

Extended Detection Window

Hair follicle testing in Darden, TN, is renowned for its ability to detect drug use over an extended period, up to 90 days. This long detection window offers a thorough and comprehensive understanding of an individual's substance use history, surpassing the capabilities of other testing methods. Employers gain valuable insights into a candidate or employee's past behavior, enabling informed decision-making.

The extended observation timeframe helps in identifying consistent patterns rather than isolated incidents. This facility empowers companies and legal bodies to maintain safer environments. The prolonged detection capacity is a major advantage for program administrators and employers enforcing drug-free policies.

Tamper-Resistant Testing Method

In Darden, TN, hair follicle tests offer a tamper-resistant alternative when it comes to drug screening. This method significantly reduces the likelihood of sample adulteration, providing reliable and unquestionable outcomes. The process of obtaining hair samples is transparent and simple, ensuring the integrity and legality of the results.

Due to these characteristics, hair follicle testing has become a favored method among employers who prioritize workplace safety and compliance with drug-free policies. The difficulty in altering the sample means stakeholders can trust the results, avoiding the faults that can sometimes arise with more traditional methods like urine tests.
