Hair Follicle Drug Testing - Lipscomb, AL

What it is, How it works

Seen as a potent diagnostic method for identifying drug and alcohol consumption, hair testing captures a comprehensive timeline of such substances by embedding biomarkers within the hair fibers as they grow. Hair specimens collected near the scalp are capable of revealing drug and alcohol usage over roughly a 90-day span. Collecting hair is straightforward, comparatively tamper-resistant, and convenient to transport.

A 1.5-inch segment comprising around 200 hair strands (comparable to the thickness of a #2 pencil) proximal to the scalp renders 100mg, the optimal quantity for both preliminary and confirmatory analysis. For EtG, add-ons, and/or tests exceeding 10 panels, a collection of 150mg is advised. Utilizing a jeweler’s scale to weigh the specimen is advisable. Should scalp hair be inaccessible, an equivalent volume of body hair is permissible. By head hair, we specifically mean scalp hair; body hair pertains to any other hair type (such as facial, axillary, etc.).

Process Overview

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

During Accessioning, the sample undergoes initial processing within the laboratory’s framework. This step ensures the sample was appropriately sealed and dispatched, assigns a unique LAN (Laboratory Accessioning Number), and finalizes any additional data entry absent from an electronic chain of custody system.

Screening acts as an initial preliminary evaluation for substances of abuse. While Screening efficiently eliminates suspicions of drug usage in most instances, any positive findings from this stage require verification before being acceptable for legal procedures. Those samples that test presumptively positive during Screening necessitate an additional validation.

Should the Screening phase yield a presumptive positive result, additional hair is extracted from the initial specimen, refined for Extraction. During Extraction, drug substances are isolated from hair at comparatively lower concentrations than those in other methodologies (e.g., urine or oral fluid), contributing to the complexity of conducting hair drug analysis effectively.

Confirmation of a positive result from the Screening phase is performed using GC/MS, GC/MS/MS, or LC/MS/MS methods. Every sample that tests presumptive positive is cleansed before confirmation if necessary. The end-to-end laboratory protocol, from Accessioning to Confirmation, is subject to evaluation by both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug assessments can trace drug usage for a maximum of 90 days, surpassing the shorter detection period typical of urine testing.
• Minimized likelihood of manipulation: The difficulty of manipulating hair drug tests enhances the reliability of the results.
• Historical insight: This testing method elucidates trends in drug usage over time rather than indicating merely recent consumption.

Limitations:

• Inability to detect recent consumption: Detection of drugs in hair necessitates approximately 5-7 days post-consumption.
• Expense considerations: Hair drug assessments generally entail higher costs than alternative testing methodologies.
• Result variability: Elements like hair color and personal discrepancies in hair growth potentially affect the level of drug metabolites within the hair.

Note: Although often termed "hair follicle tests", this evaluation examines the hair strand itself, rather than the follicle beneath the scalp.
