Hair Follicle Drug Testing - Drexel, NC

What it is, How it works

Hair testing has emerged as an effective means for identifying drug and alcohol consumption. It offers a comprehensive history of substance use by capturing biomarkers within the expanding fibers of the hair strand. When gathered near the scalp, hair can reveal alcohol and drug use over a window of up to roughly 3 months. Collecting hair is straightforward, tampering is relatively challenging, and shipping is hassle-free.

A sample measuring 1.5 inches and containing around 200 hair strands (comparable in size to a #2 pencil) taken close to the scalp will yield 100mg of hair, which is optimal for both screening and confirmation. For additional tests such as EtG and tests beyond 10 panels, a specimen of 150mg is advised. We suggest using a jeweler’s scale to weigh the sample. If scalp hair is unavailable, collecting an equivalent amount of body hair is an option. When mentioning head hair, we specifically mean scalp hair. In contrast, body hair pertains to all other hair types, including facial and axillary hair.

Process Overview

The processing of a drug test result in the laboratory involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the initial stage of integrating a sample into a laboratory system. The process includes verifying the correct sealing and shipping of the sample, assigning it a unique LAN (Laboratory Accessioning Number), and filling in any missing data not captured by an electronic chain of custody.

Screening entails a preliminary assessment for substances of abuse. Though it serves as a cost-effective measure to identify drug usage in most samples, a positive screen needs validation to be legally valid in court. Samples that yield presumptively positive results during Screening require further confirmation.

Should a sample show a presumptive positive in the Screening phase, additional hair is extracted from the original sample for the Extraction process. At this stage, substances are drawn from the hair at significantly lower concentrations than other methods (like urine or oral fluid), making hair drug screening the most challenging tactic to undertake.

Confirmation of a positive screening outcome is carried out via GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all samples with presumptive positives are cleaned as necessary. Each segment of the laboratory procedure from Accessioning to Confirmation is subject to evaluation under the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation.

Advantages of hair drug testing:

• Long detection window: Detects drug use for up to 90 days, in contrast to urine tests which offer a shorter detection window.
• Difficulty to cheat: Hair drug tests are very resistant to tampering, leading to more reliable outcomes.
• Provides historical data: It offers insights into patterns of drug use over time, unlike tests that only identify recent use.

Limitations:

• Cannot detect recent use: It requires approximately 5-7 days for drugs to be identified in hair.
• Cost: Hair drug tests typically incur higher costs than other testing methods.
• Variations in results: Factors like hair color and individual hair growth differences can influence the drug metabolite levels in the hair.

Note: While termed "hair follicle tests", the analysis focuses on the hair strand rather than the follicle beneath the scalp.
