Hair Follicle Drug Testing - Indian Hills, TX

What it is, How it works

Recognized for its effectiveness, hair testing serves as a robust method for identifying drug and alcohol consumption. Hair captures a comprehensive timeline of substance use by embedding biomarkers within its structure. When sampled near the scalp, hair can reveal substance use over an approximately 3-month period. The collection process of hair is straightforward, challenging to tamper with, and convenient to transport.

Obtaining a 1.5-inch sample comprising roughly 200 hair strands (comparable to the width of a #2 pencil) near the scalp yields 100mg of hair, optimal for screening and validation. For EtG, extended panels, and tests exceeding 10 panels, 150mg is advisable. Utilizing a jeweler’s scale for measuring the specimen is recommended. If scalp hair is unavailable, a comparable quantity of body hair may be used. References to head hair specifically pertain to scalp hair, whereas body hair encompasses other hair types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result involves four pivotal steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial integration of a sample into a laboratory’s system. This phase includes ensuring the sample's proper sealing and transport, assigning a random LAN (Laboratory Accessioning Number), and finishing any supplementary data input absent from an electronic chain of custody system.

Screening consists of an initial, rapid examination for drug presence. Although Screening provides a cost-efficient method to negate drug usage for most samples, a positive screening outcome necessitates confirmation for court acceptance. Samples yielding presumptive positives during Screening must undergo a secondary verification.

In cases of a presumptive positive during Screening, additional hair is extracted from the initial sample for the Extraction phase. This phase involves extracting drugs from hair at significantly lower concentrations than other methodologies (such as urine or oral fluid), highlighting why hair drug screening is the most intricate method to execute.

Confirmation of any presumptive positive from screening is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All such samples undergo washing prior to confirmation if necessary. From Accessioning to Confirmation, the entire laboratory process is reviewed under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug use for up to 90 days, in contrast to the shorter timeframe of urine tests.
• Resilient to manipulation: Hair drug tests are highly resistant to tampering, enhancing result accuracy.
• Chronological data provision: This method can illustrate a pattern of drug use over time, beyond immediate usage.

Limitations:

• Inability to detect recent usage: There is a 5-7 day delay before drugs become detectable in hair.
• Expense: Hair drug tests tend to be costlier than alternative testing methods.
• Result variability: Factors like hair color and individual hair growth rates can influence drug metabolite levels in hair.

Note: Although commonly known as "hair follicle tests", the examination is conducted on the hair strand itself, not the follicle located beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Indian Hills, hair follicle testing is seen as superior to traditional urine tests due to exceptional detection accuracy and reliability. Hair tests are less prone to adulteration and provide a longer detection period.

Unlike urine tests, which may only capture recent use, hair follicle tests offer a more comprehensive view of an individual's substance use over time, making them a more effective choice for employers.

Extended Detection Window

Hair follicle testing boasts an extended detection window of up to 90 days, giving a thorough portrayal of drug usage history. This feature in Indian Hills provides employers a detailed overview of an employee or applicant's substance use habits.

This prolonged detection period is valuable for maintaining workplace safety and ensuring a trustworthy workforce, as it detects usage that might not be captured by other testing methods.

Tamper-Resistant Testing Method

In Indian Hills, the tamper-resistant nature of hair tests makes them a trustworthy option. The reduced likelihood of sample adulteration ensures that results reflect true substance use, providing accurate and decisive data.

This level of security in testing is crucial for upholding a drug-free environment and ensures that employers can rely on test outcomes without concern of manipulation.
