Hair Follicle Drug Testing - Nashville, AR

What it is, How it works

Hair testing is recognized as an effective means for identifying drug and alcohol consumption. The hair captures a prolonged substance use history by embedding biomarkers within the fibers as they grow. When hair is sourced near the scalp, it offers about a 90-day detection period for alcohol and drugs. Hair is straightforward to collect, hard to tamper with, and simple to transport.

A 1.5-inch section comprising roughly 200 strands of hair (approximately akin to a #2 pencil) nearest to the scalp yields 100mg of hair, ideal for both screening and confirmation processes. For EtG, extra markers, and tests beyond 10 panels, a 150mg quantity of the sample is advisable. It is suggested to use a jeweler’s scale to weigh the sample. Should scalp hair be unavailable, a comparable quantity of body hair may be taken. Note that 'head hair' denotes scalp hair alone, whereas 'body hair' encompasses all other types (facial, axillary, etc.).

Process Overview

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

Accessioning includes the sample’s initial integration into the lab’s system. This encompasses checks on proper sealing and shipping, issuing a random LAN (Laboratory Accessioning Number), and finalizing any extra data input absent from an electronic chain of custody system.

Screening provides a preliminary evaluation for substance abuse. Despite being a cost-effective approach to exclude drug use in most samples, a positive screen requires confirmation to be court-admissible. Presumptive positives in Screening necessitate a subsequent confirmation.

If the Screening step results in a presumptive positive, more hair is extracted from the original sample and readied for Extraction. During this phase, drugs are drawn from the hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), underscoring the complexity of hair drug screening.

Confirmation of any positive results from screening occurs via GC/MS, GC/MS/MS, or LC/MS/MS. All samples testing presumptive positive undergo washing before confirmation as required. The entire lab process from Accessioning to Confirmation is scrutinized under both CAP (College of American Pathologists) Hair standards and accredited ISO / IEC 17025 norms.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests detect substance use for up to 90 days, offering a longer window than urine tests.
• Hard to manipulate: Cheating on a hair drug test is highly challenging, enhancing result reliability.
• Historical insight: Users’ drug consumption patterns over time are revealed, rather than just recent use.

Limitations:

• Incapable of recent use detection: Drugs become discernible in hair approximately after 5-7 days.
• Expense: Generally, hair drug tests entail higher costs compared to other testing approaches.
• Result disparities: Hair color and personal hair growth variability may influence drug metabolite concentrations in the hair.

Note: Though frequently termed "hair follicle tests," these tests examine the hair strand itself rather than the follicle beneath the scalp.
