Hair Follicle Drug Testing - Grayson, AL

What it is, How it works

Hair analysis has emerged as an effective instrument for identifying drug and alcohol consumption. Hair retains a long-term record of use by embedding biomarkers within the fibers of the growing strands. When obtained near the scalp, hair can reveal a detection period of up to three months for drugs and alcohol. The collection process for hair is straightforward, somewhat immune to tampering, and convenient for shipping.

A specimen of 1.5 inches from around 200 hair strands (approximating the size of a #2 pencil) nearest to the scalp will yield 100mg, which is optimal for both screening and confirmation. When testing for EtG, add-ons, and/or beyond 10 panels, a 150mg specimen is advised. We suggest utilizing a jeweler’s scale for accuracy. If scalp hair is unavailable, an equivalent amount of body hair can be gathered. Mention of head hair specifically implies scalp hair. In contrast, body hair encompasses all other hair types (like facial or axillary hair).

Process Overview

The laboratory procedure for processing a drug test result involves four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a sample into the lab's system. This step confirms the sample's proper sealing and transport, issues a random LAN (Laboratory Accessioning Number), and completes any supplemental data entry not managed by an electronic chain of custody.

Screening executes a preliminary, rapid examination for substances of abuse. Although Screening offers an economical method for ruling out drug use across most samples, a positive result necessitates confirmation for court acceptance. Any samples showing preliminary positivity in Screening must undergo a secondary verification.

For samples that indicate provisional positivity in Screening, additional hair is extracted from the initial sample and prepped for Extraction. This phase entails extracting drugs from hair at a significantly lower concentration than alternative methods (such as urine or oral fluid), thus highlighting the complexity of hair drug screening.

Confirmation of a positive result from the Screening stage is performed through GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptive positive samples undergo washing before confirmation if required. The entire lab procedure from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair designation and complies with the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can trace drug consumption up to 90 days, unlike urine tests which exhibit a briefer detection period.
• Hard to circumvent: Cheating on a hair drug test is exceedingly challenging, thus enhancing result accuracy.
• Delivers historical insight: It unveils a pattern of substance use over time, in contrast to merely recent consumption.

Limitations:

• Incapable of spotting recent use: It requires approximately 5-7 days for drugs to manifest in hair.
• Expense: Hair drug tests typically incur higher costs than other testing methods.
• Result variability: Elements like hair color and individual growth rates can distort drug metabolite concentrations within hair.

Note: Despite being occasionally termed "hair follicle tests", these tests analyze the hair strand as opposed to the follicle beneath the scalp.
