Hair Follicle Drug Testing - Brownsville, TX

What it is, How it works

Hair analysis is now acknowledged as a robust method for detecting drug and alcohol consumption. Hair captures a comprehensive history of alcohol and drugs by embedding biomarkers within the hair's fibers as it grows. When gathered near the scalp, hair can furnish up to a roughly 3-month period for detecting alcohol and numerous drugs. Its collection is straightforward, relatively challenging to tamper with, and it is convenient to transport.

A sample measuring 1.5 inches consisting of around 200 hair strands (approximately comparable to a #2 pencil's thickness) nearest to the scalp can yield 100mg of hair, which is the optimal sample size for both screening and confirmation purposes. For EtG, additional testing, and/or evaluations beyond 10 panels, a recommendation of 150mg of the sample is advised. We suggest employing a jeweler’s scale for measuring the sample. Should scalp hair be unavailable, an equivalent amount of body hair may be utilized. References to head hair pertain only to scalp hair. In contrast, body hair encompasses all other types (like facial and axillary hair).

Process Overview

The procedure for processing a drug test result in a laboratory encompasses four fundamental steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the preliminary processing of a specimen into a laboratory's system. This phase includes confirming that the sample was appropriately sealed and delivered, issuing a random LAN (Laboratory Accessioning Number), and executing any additional data entry that an electronic chain of custody system did not cover.

Screening refers to an initial rapid evaluation for drugs of abuse. While Screening presents a cost-effective mechanism for excluding drug use across most samples, a Confirmed positive screen is necessary for court admissibility. Samples displaying presumptive positive results in Screening necessitate a follow-up confirmation.

When a sample shows a presumptive positive in the Screening phase, more hair is extracted from the initial sample and readied for Extraction. In this phase, drugs are extracted from hair at a concentration significantly lower than other methods (e.g., urine or oral fluid), accentuating why hair drug screening is a more arduous methodology to execute.

Confirmation of any positive result from Screening is executed through GC/MS, GC/MS/MS, or LC/MS/MS. Any samples thought presumptively positive are cleansed prior to Confirmation depending on necessity. Each segment of the laboratory process from Accessioning to Confirmation is subject to review under both the CAP (College of American Pathologists) Hair accreditation and the ISO / IEC 17025 standard certifications.

Advantages of hair drug testing:

• Extended detection duration: Hair drug evaluations can identify drug consumption for up to 90 days, contrary to urine tests which present a briefer detection period.
• Increased difficulty for manipulation: Cheating a hair drug evaluation is notably difficult, ensuring more precise results.
• Chronological data provision: It supplies an insight into the drug use profile across time, not just recent consumption.

Limitations:

• Inability to detect recent consumption: It requires around 5-7 days for substances to become detectable in hair.
• Expense: Hair drug evaluations tend to attract higher costs compared to alternate drug testing methodologies.
• Result variabilities: Factors such as hair pigmentation and individual hair growth discrepancies can influence the presence of drug metabolites in hair.

Note: Despite being colloquially termed as "hair follicle tests", the actual analysis is conducted on the hair strand itself, excluding the hair follicle situated beneath the scalp.
