Hair Follicle Drug Testing - North Cowden, TX

What it is, How it works

Hair analysis is recognized as an effective method for detecting drug and alcohol consumption. Hair holds a comprehensive record of alcohol and drug intake by capturing biomarkers within the hair fiber as it grows. By collecting hair near the scalp, one can achieve a detection period spanning up to approximately three months for alcohol and drugs. Gathering hair is straightforward, relatively tamper-resistant, and convenient for dispatch.

A sample consisting of 1.5 inches of approximately 200 hair strands (about the thickness of a #2 pencil) nearest to the scalp equates to 100mg of hair, which is the optimal quantity for evaluation and confirmation. For EtG, additional tests, or tests exceeding 10 panels, a recommendation of 150mg is suggested. It's advisable to measure the sample using a jeweler’s scale. If scalp hair is not accessible, an equivalent amount of body hair can be utilized. When mentioning head hair, we are specifically referring to scalp hair alone. Body hair pertains to all other hair categories (facial, axillary, etc.).

Process Overview

The key procedures in the laboratory processing of a drug test result comprise Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary handling of a sample within a lab's system. This step includes ensuring the sample is properly sealed and dispatched, attributing a unique LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry absent from an electronic chain of custody mechanism.

Screening represents an initial rapid evaluation for drug abuse. Screening serves as a cost-efficient technique to rule out drug usage in the majority of samples; however, a positive screen must be validated to be permissible in court. Any samples with presumptive positive results in Screening necessitate secondary confirmation.

In cases where a sample shows a presumptive positive during the Screening phase, more hair is extracted from the original sample and prepared for Extraction. During this phase, drugs are extracted from hair at concentrations much lower than in alternative methods (e.g., urine or oral fluid), making hair drug screening the most complex method to administer.

Confirmation of any positive screening outcome is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation if required. The entire lab operation from Accessioning to Confirmation is thoroughly reviewed under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use over a 90-day period, whereas urine tests offer a shorter detection range.
• Complexity to manipulate: Outwitting a hair drug test is exceptionally difficult, enhancing result reliability.
• Delivers historical insights: It can reveal drug use patterns over a timeline, beyond just recent consumption.

Limitations:

• Inability to detect recent consumption: It takes roughly 5-7 days for drugs to become evident in hair.
• Expense: Hair drug tests commonly cost more than other drug testing techniques.
• Result variations: Elements like hair color and individual hair growth disparities may influence drug metabolite concentration in the hair.

Note: Although termed as "hair follicle tests", the actual test examines the hair strand and not the follicle beneath the scalp.
