Hair Follicle Drug Testing - North Wilkesboro, NC

What it is, How it works

Hair analysis is increasingly valued as an effective technique for identifying alcohol and other drug consumption. Hair serves as a long-term record by embedding biomarkers within the strands of hair as they grow. Sampling hair from near the scalp can offer a detection timeframe for substances up to roughly three months. The process is straightforward, challenging to tamper with, and simple to transport.

A sample measuring 1.5 inches, containing around 200 hair strands (equivalent to the thickness of a #2 pencil), taken closest to the scalp, should amount to 100mg, which is ideal for examination and verification. For EtG evaluations, additional testing, or assessments exceeding 10 panels, a larger 150mg sample is suggested. It's advisable to weigh the hair on a jeweler’s scale. If scalp hair isn’t accessible, equivalent body hair can be used. "Head hair" refers specifically to scalp hair, whereas "body hair" includes all other hair varieties, such as facial or axillary.

Process Overview

The laboratory assessment process for drug testing consists of four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning addresses the initial intake of a specimen into the lab's system, ensuring the sample’s integrity and proper transmission, generating a unique LAN (Laboratory Accessioning Number), and finalizing outstanding data input not covered by an electronic chain of custody system.

Screening promptly evaluates the sample for drug presence. Although Screening economically eliminates drug use in most cases, a positive result requires confirmation to be permissible legally. Samples flagged as presumptively positive in Screening necessitate further validation.

Positive findings in the Screening phase lead to additional hair being sourced from the initial specimen for Extraction. In this phase, drugs are retrieved from hair at significantly minimized concentrations compared to alternative methods (e.g., urine or oral fluid), thereby making hair drug testing one of the most intricate methodologies to execute.

Positive Screening outcomes undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptive positives receive a preparatory wash prior to confirmation if required. The entire procedure from Accessioning to Confirmation is evaluated according to both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection range: Hair drug assessments can identify drug usage over a period of up to 90 days, whereas urine tests offer a more limited detection span.
• Challenging to deceive: Cheating a hair drug test is extremely difficult, ensuring more reliable test outcomes.
• Illustrates usage history: Hair tests can reveal a timeline of drug usage, not merely recent consumption.

Limitations:

• Limited in detecting recent consumption: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Generally, hair drug assessments are pricier than other testing approaches.
• Variability in outcomes: The concentration of drug metabolites in hair can be influenced by hair color and individual growth differences.

Note: Although often termed "hair follicle tests", the analysis focuses on the hair strand itself and not the underlying follicle.
