Hair Follicle Drug Testing - Indian Mound, TN

What it is, How it works

Hair assessments have emerged as an effective method for detecting alcohol and drug usage. The fibers of growing hair encapsulate biomarkers, providing an extended timeline of drug and alcohol presence. Collecting hair close to the scalp offers roughly a 90-day detection period for such substances. It's straightforward to collect, relatively tamper-proof, and convenient to mail.

A sample measuring 1.5 inches with about 200 hair strands, akin to the width of a #2 pencil, yields 100mg, optimal for analysis. For EtG tests, additional panels above 10, or add-ons, a specimen weight of 150mg is advisable. Use a jeweler's scale for precise measurement. If scalp hair isn't available, a similar volume of body hair may be used. References to head hair specifically concern scalp hair, whereas body hair references include all other types like facial and axillary hair.

Process Overview

The laboratory procedure for evaluating a drug test encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample is initially logged into a lab's system. This step certifies the sample's proper sealing and shipment, assigns a LAN (Laboratory Accessioning Number) randomly, and completes any pending data entries not covered by an electronic custody system.

Screening entails an initial cursory evaluation for drug abuse substances. Though an economical approach to exclude drug use in most samples, results indicating positivity in Screening necessitate further confirmation for legal admissibility. Presumptive positives in Screening move on to secondary verification.

For a presumptive positive result from Screening, additional hair is extracted from the original sample for further preparation in Extraction. Here, drugs are isolated at significantly lower concentrations than in other methods like urine or saliva, underscoring the complexity of hair drug assessments.

Confirmation of any positive screen occurs through GC/MS, GC/MS/MS, or LC/MS/MS methodologies. Presumptive positive samples undergo cleansing before Confirmation as needed. The comprehensive laboratory process, from Accessioning to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair designation and complies with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection duration: Hair tests reveal drug use over a span of up to 90 days, more so than urine tests with shorter detection times.
• Challenging to manipulate: Cheating a hair drug test is exceptionally tough, enhancing the accuracy of the results.
• Chronological data provision: It elucidates a pattern of drug usage over time, beyond just recent intake.

Limitations:

• Incapable of identifying recent consumption: Drugs are detectable in hair after an estimated period of 5-7 days.
• Expense: Hair drug tests tend to be pricier than alternate testing methods.
• Result variability: Elements like hair color and personal hair growth differences can alter drug metabolite concentrations in hair.

Note: Despite being commonly known as "hair follicle tests", the analysis actually targets the hair strand itself, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

When comparing hair follicle testing to traditional urine tests, the superior detection accuracy and reliability of hair tests stand out in Indian Mound, TN. Hair tests cover an extensive detection window, unlike urine tests that only capture recent use. This enables a more thorough examination of an individual's substance history, supporting informed decisions.

Urine tests may fall short in unveiling long-term patterns, often only indicating recent consumption. In contrast, hair follicle tests deliver extensive insights into drug use, covering up to 90 days, ensuring employers and courts receive the most reliable results.

Extended Detection Window

Hair follicle tests, especially in places like Indian Mound, TN, provide a comprehensive detection window that extends up to 90 days. This extended time frame empowers employers to gain deeper insights into an individual’s substance use history, surpassing the limited scope of traditional tests like urine.

The long detection period with hair testing is invaluable for creating an extensive understanding of potentially detrimental patterns, offering perspectives far beyond recent use. Employers hence benefit from a more rounded assessment.

Tamper-Resistant Testing Method

In Indian Mound, TN, hair follicle testing stands out due to its tamper-resistant nature. The sampling process greatly diminishes the likelihood of adulteration, ensuring that results are both reliable and indisputable. This method offers certain assurance compared to other testing options, making it highly trusted by employers and organizations alike.
