Hair Follicle Drug Testing - Seymore, TX

What it is, How it works

Hair examinations are increasingly recognized as an effective means for uncovering drug and alcohol consumption. Hair maintains an extended record of alcohol and other drugs by embedding biomarkers within the fibers of the hair as it grows. When obtained from near the scalp, hair samples can offer up to a 90-day detection timeframe for alcohol and other drugs. Hair is straightforward to collect, challenging to tamper with, and convenient to transport.

A 1.5-inch segment of roughly 200 hair strands (approximately the girth of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal sample size for evaluation and verification. For EtG, additional analyses, and/or assessments exceeding 10 panels, 150mg of the sample is advised. It is suggested to measure the specimen on a jeweler’s scale. If scalp hair is not present, a comparable amount of body hair can be used. When discussing head hair, we specifically mean scalp hair. Body hair pertains to all other hair types (facial, axillary, etc.).

Process Overview

The four key phases in the lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning constitutes the initial processing of a sample into a lab’s system. This process verifies that the sample has been correctly sealed and dispatched, allocates a random LAN (Laboratory Accessioning Number), and completes any additional data input not available via an electronic chain of custody system.

Screening consists of an initial rapid evaluation for drugs of misuse. Although Screening is an economical way to exclude drug use in most samples, a positive result must be confirmed for court admissibility. Any samples with a presumptive positive in Screening necessitate further confirmation.

If a sample is indicated as presumptively positive during the Screening phase, additional hair is extracted from the original sample and prepared for Extraction. During this phase, drugs are isolated from hair at a significantly lower concentration than in other techniques (e.g. urine or oral fluid), which makes hair drug testing the most intricate method to execute.

Verification of any positive screen results is done via GC/MS, GC/MS/MS or LC/MS/MS. All samples that are presumptive positive undergo washing prior to confirmation as required. The comprehensive lab procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection span: Hair drug assessments can recognize drug use for up to 90 days, unlike urine tests, which offer a brief detection span.
• Difficult to deceive: It is notably challenging to deceive a hair drug test, making outcomes more precise.
• Provides usage history: It can outline a pattern of drug consumption over time, as opposed to recent use alone.

Limitations:

• Incognizant of recent usage: It roughly takes 5-7 days for drugs to manifest in hair.
• Expense: Hair drug tests are usually pricier than other drug testing techniques.
• Result irregularities: Factors like hair color and individual differences in hair growth can influence drug metabolite levels in hair.

Note: Although often called "hair follicle tests", the test targets the hair strand and not the follicle under the scalp

Why Hair Follicle Testing Beats Urine Testing

Why is hair follicle testing favored over urine tests in Seymore, TX? The answer lies in superior detection accuracy and reliability. Hair tests provide a broader detection window, revealing drug use long after a substance has left the system. This accuracy offers peace of mind, ensuring that results reflect true substance use patterns without the variability often seen in urine testing.

The hair testing process is less susceptible to adulteration, which gives employers confidence in the results. This level of trust is crucial in maintaining fair and transparent drug-testing policies.

Extended Detection Window

The extended detection window of hair follicle tests in Seymore, TX, offers a distinct advantage. Spanning up to 90 days, this timeframe provides a holistic view of an individual’s drug use history. For employers, this comprehensive snapshot is invaluable, offering insights into long-term behavior patterns rather than just recent activities.

This period also aligns well with the probationary periods often set by companies for new hires, ensuring ongoing compliance with drug-free policies.

Tamper-Resistant Testing Method

One key allure of hair follicle drug testing in Seymore, TX, is its tamper-resistant nature. Unlike other methods, which can be compromised, hair tests are collected under controlled conditions, minimizing the risk of sample adulteration.
