Hair Follicle Drug Testing - Chadbourn, NC

What it is, How it works

Hair testing is now recognized as an effective method for detecting drug and alcohol consumption. By capturing biomarkers within the fibers of a growing hair strand, hair offers an extended timeline for alcohol and drug use history. When hair is collected near the scalp, it enables approximately a three-month detection period for substances. The process of gathering hair is straightforward, with minimal risk of tampering, and it can be easily transported.

Collecting a 1.5-inch sample, which includes about 200 strands of hair (roughly the girth of a #2 pencil) nearest to the scalp, yields 100mg of hair, which serves as the perfect sample for both screening and confirmation. For EtG, add-ons, and tests beyond 10 panels, a 150mg specimen is advised. A jeweler’s scale is recommended for weighing the specimen. In situations where scalp hair is not accessible, a similar volume of body hair can be utilized. When discussing head hair, the reference is specifically to scalp hair. Body hair encompasses all other varieties (such as facial, axillary, etc.).

Process Overview

The drug testing laboratory procedure is comprised of four principal stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial integration of a sample into the lab's system. Tasks include verifying proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent through an electronic chain of custody system.

Screening entails an expedited check for drug abuse substances. While this method is economical for negating drug use across the majority of samples, a positive screen must be corroborated for court admissibility, necessitating a follow-up confirmation for any samples with presumptively positive results in Screening.

Upon a presumptively positive finding at the Screening phase, additional hair is extracted from the original specimen and readied for Extraction. At this juncture, drug substances are extracted from hair at lower concentrations than in other methodologies (such as urine or oral fluid), underscoring the complexity of hair drug screening versus other methods.

Positive screening results achieve confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, any presumptive positive samples undergo washing as necessary. The complete laboratory process, from Accessioning through Confirmation, is conducted under the purview of both the CAP (College of American Pathologists) Hair designation and the accreditation per ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug intake for up to 90 days, contrasting with urine tests which have a briefer detection window.
• High resistance to tampering: Cheating a hair drug test is extremely challenging, thus enhancing result accuracy.
• Supplies historical patterns: This method delineates drug consumption trends over time, beyond merely recent usage.

Limitations:

• Lacks detection of recent use: Drugs take around 5-7 days to become discernible in hair.
• Expense: Hair drug tests are typically pricier than alternative testing forms.
• Result variations: Elements like hair color and individual hair growth discrepancies can influence drug metabolite concentrations in the hair.

Note: While commonly termed as "hair follicle tests," the examination evaluates the hair strand itself, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing surpasses traditional urine tests in Chadbourn, NC, offering more reliable results.
