Hair Follicle Drug Testing - McFaddin, TX

What it is, How it works

Seen as an effective means for detecting drug and alcohol usage, hair testing is advantageous. Hair captures biomarkers in the fibers of the growing strand, offering a prolonged history of substance usage. When gathered close to the scalp, hair can showcase approximately a 3-month detection period for substances like alcohol and drugs. It's uncomplicated to collect, moderately challenging to tamper with, and straightforward to dispatch.

A sample measurement of 1.5 inches consisting of about 200 hair strands (comparable in size to a #2 pencil) from near the scalp will yield 100mg of hair, which serves as the perfect sample for both screening and confirmation purposes. For EtG, additional tests, or panels exceeding 10, a specimen massing 150mg is preferred. It is advised to measure the sample with a jeweler’s scale. In the absence of scalp hair, an equivalent portion of body hair can be collected. When referencing head hair, it particularly pertains to scalp hair only. All other hair types, such as facial or axillary, are referred to as body hair.

Process Overview

Four critical steps are entailed in the lab processing of a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.

Accessioning constitutes the initial integration of a sample into a lab’s records. This phase verifies that the sample was appropriately sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and accomplishes any supplementary data recording absent in an electronic custody chain system.

Screening is a baseline rapid evaluation for commonly abused drugs. While financially efficient in dismissing drug usage across numerous samples, a positive screening necessitates confirmation for legal admissibility. Samples assessed as presumptively positive during Screening necessitate secondary verification.

In the event of a presumptive positive result at the Screening phase, additional hair is extracted from the original sample for the Extraction process. In this phase, drugs are isolated from the hair at notably lower concentrations relative to other methods (e.g., urine or oral fluid), which makes hair drug screening one of the most intricate methodologies.

Verification of any positive screening finding is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. All samples marked as presumptive positive undergo washing prior to confirmation when necessary. The complete lab procedure, starting from Accessioning and culminating in Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair designation and accredited to the ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection period: Hair drug testing can reveal drug usage extending up to 90 days, unlike urine tests which have a briefer detection timeframe.
• Cheating resistance: It's exceedingly challenging to deceive a hair drug test, thus enhancing result accuracy.
• Historical data provision: It offers a drug usage trend over time, rather than just recent consumption.

Limitations:

• Non-detection of recent usage: Drugs become detectable in hair roughly 5-7 days post-consumption.
• Expense: Hair drug tests tend to be costlier than alternative drug testing techniques.
• Result variability: Aspects like hair color and individual hair growth variance can influence drug metabolite concentration in hair.

Note: While commonly termed as "hair follicle tests", the assessment focuses on hair strands rather than the scalp’s hair follicle.
