Hair Follicle Drug Testing - St. Martinville, LA

What it is, How it works

Hair analysis is now recognized as a significant instrument for identifying drug and alcohol consumption. The hair captures a prolonged record of alcohol and other substances by embedding biomarkers within its growing fibers. When acquired near the scalp, it can reveal up to a roughly three-month period of drug and alcohol detection. Collecting it is straightforward, it's relatively hard to tamper with, and it can be easily transported.

A 1.5-inch section comprising around 200 hair strands (comparable to the thickness of a #2 pencil) closest to the scalp yields 100mg of hair, which is the perfect sample for both screening and confirmation. For EtG, additional tests, or analyses exceeding 10 panels, a 150mg sample is advised. It's prudent to use a jeweler's scale to measure the specimen. In instances where scalp hair is not an option, an equivalent volume of body hair can be utilized. References to head hair imply strictly scalp hair. Body hair encompasses every other type of hair (such as facial, axillary, etc.).

Process Overview

The key stages in the laboratory process to validate a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial integration of a sample into a laboratory’s framework. This processes verifying that the specimen was properly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and conducts any supplementary data entry absent from an electronic chain of custody setup.

Screening delivers an initial quick assessment for drugs of manipulation. Although Screening presents a budget-friendly approach to exclude drug utilization in most specimens, a favorable screen necessitates affirmation for court admissibility. Any samples flagged as presumptively positive in Screening necessitate secondary confirmation.

Should a specimen show a presumptive positive in the Screening phase, more hair is retrieved from the initial sample and prepped for Extraction. Drugs are then extracted from the hair at notably lower concentrations than in other techniques (such as urine or oral fluid), making hair drug analysis the most intricate method to execute.

Any positive screening outcome is validated through GC/MS, GC/MS/MS, or LC/MS/MS. All specimens with presumptive positives are appropriately cleansed before confirmation. The comprehensive lab protocol from Accessioning to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair specification and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection span: Hair drug assessments can reveal drug consumption up to 90 days, in contrast to urine assessments which present a reduced detection span.
• Challenging to manipulate: It is exceptionally challenging to deceive a hair drug test, hence improving result validity.
• Offers historical insights: It can indicate a drug use pattern across a timeline, rather than merely recent usage.

Limitations:

• Unable to detect recent activity: Drugs become noticeable in hair approximately 5-7 days post-consumption.
• Expense: Hair drug evaluations generally incur greater costs than alternative drug testing techniques.
• Result discrepancies: Variables like hair pigmentation and personal variations in hair growth can sway drug metabolite concentrations in the hair.

Note: The term "hair follicle tests" is popular but the test targets the hair strand rather than the follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing undoubtedly outperforms urine testing in St. Martinville, LA. One primary reason is its superior detection accuracy. Unlike urine tests, which can only detect recent use, hair tests cover a longer span, providing a more comprehensive evaluation.

By examining drug use indicators for up to 90 days, it provides employers an in-depth view of an individual's substance history. This is particularly beneficial for assessing long-term behavior rather than isolated incidents, assisting in hiring decisions. With a broader temporal scope, hair testing tends to be more holistic than other methods.

Tamper-Resistant Testing Method

The tamper-resistant design of hair follicle tests in St. Martinville, LA, greatly reduces the chances of sample manipulation. Such tests offer a layer of security that urine tests lack, ensuring the integrity and trustworthiness of the results. With hair samples, the likelihood of undisclosed adulteration is minimal, offering peace of mind to both employers and testing technicians while maintaining result validity.
