Hair Follicle Drug Testing - Nocona Hills, TX

What it is, How it works

Hair analysis is recognized as a robust method for identifying substance use, capturing a prolonged timeline of drug and alcohol exposure by embedding biomarkers within the threads of maturing hair. When procured near the scalp, hair can reveal a detection period of up to roughly three months for substances including alcohol. The collection of hair is straightforward, relatively tamper-resistant, and uncomplicated to dispatch.

A 1.5-inch section consisting of roughly 200 hair strands (comparable to a #2 pencil) adjacent to the scalp yields 100mg, which is the optimal amount for both screening and verification. For EtG enhancements and/or analyses beyond 10 panels, a specimen mass of 150mg is advisable. Utilizing a jeweler’s scale for weighing the sample is suggested. Should scalp hair be inaccessible, an equivalent quantity of body hair is acceptable. When mentioning head hair, it specifically pertains to scalp hair. Body hair encompasses all other varieties (facial, axillary, etc.).

Process Overview

Laboratory processing of a drug test outcome encompasses four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning incorporates the initial processing phase of integrating a sample into a lab’s system. This involves verifying the proper sealing and shipping of the sample, assigning an arbitrary LAN (Laboratory Accessioning Number), and conducting any supplementary data entry absent in an electronic chain of custody framework.

Screening involves a preliminary rapid assessment for drugs of abuse. Although Screening offers a cost-efficient means for ruling out drug use in most samples, any positive findings necessitate validation to be recognized in legal proceedings. Samples that are tentatively positive during Screening require a further confirmation.

Should a sample be tentatively positive during the Screening phase, additional hair is extracted from the original sample and readied for Extraction. At this stage, substances are drawn from hair in significantly lower concentrations compared to other modalities (e.g., urine or oral fluid), which explains why hair drug screening presents the greatest challenge in terms of methodology.

Confirmatory testing of any positive screening result is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples assumed positive are cleansed before confirmation if necessary. The complete laboratory process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug evaluations can identify substance use for up to 90 days, in contrast to urine assessments which possess a briefer detection span.
• Difficult to manipulate: Manipulating a hair drug test is exceedingly challenging, enhancing result accuracy.
• Reveals historical usage: It can outline a substance usage trend over a timeline, rather than solely recent consumption.

Limitations:

• Incapable of detecting recent consumption: It requires around 5-7 days for substances to become identifiable in hair.
• Expense: Hair drug evaluations are typically more costly than alternate drug testing techniques.
• Outcome variability: Factors such as hair pigmentation and personal hair growth differences may influence drug metabolite concentrations in the hair.

Note: Although frequently termed as "hair follicle tests", the examination itself assesses the hair strand, not the follicle beneath the scalp
