Hair Follicle Drug Testing - Toltec, AZ

What it is, How it works

Hair testing has rapidly become recognized as an effective means for detecting the presence of drugs and alcohol. It provides a comprehensive view of alcohol and drug intake by embedding biomarkers within the strands of growing hair. When sourced near the scalp, hair can offer a detection period extending up to about three months for alcohol and other drugs. Its collection process is straightforward, it resists tampering, and it is convenient to transport.

A sample measuring 1.5 inches from approximately 200 hair strands (akin to the girth of a #2 pencil) nearest to the scalp yields 100mg of hair, deemed an optimal amount for both screenings and confirmations. For EtG, additional screenings, and tests exceeding 10 panels, a greater quantity of 150mg is advisable. It is suggested to weigh the sample using a jeweler’s scale. Should scalp hair be unavailable, an equal quantity of body hair may be used as a substitute. "Head hair" denotes scalp hair exclusively, while "body hair" encompasses all other hair types (such as facial, axillary, etc.).

Process Overview

The key stages in the laboratory processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the sample's initial processing within a laboratory's system. This phase includes verifying proper sealing and shipment of the sample, assigning a unique LAN (Laboratory Accessioning Number), and handling any supplementary data entry absent from an electronic chain of custody system.

Screening provides an initial, rapid assessment for substances of abuse. Although Screening presents a cost-efficient method to identify drug usage across most samples, results from a positive screen must undergo confirmation before being court-admissible. Samples featuring presumptive positive results during Screening mandate further confirmation.

Should a sample yield a presumptive positive result in Screening, additional hair is extracted from the initial specimen and readied for Extraction. Within this process, drugs are garnered from hair at much diminished concentrations compared to alternative methodologies (e.g., urine or oral fluid), underscoring why hair drug screening is considered notably challenging.

Positive screening outcomes undergo confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive specimens are cleansed prior to confirmation as necessary. The comprehensive laboratory cycle spanning from Accessioning to Confirmation is overseen according to the CAP (College of American Pathologists) Hair designation along with the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug evaluations can register drug consumption for up to 90 days, a more extensive duration than that allowed by urine tests.
• Resistance to manipulation: The difficulty in tampering with hair drug assessments equates to more assured accuracy in results.
• Chronological data: It affords insight into a pattern of substance use over time, as opposed to only recent consumption.

Limitations:

• Incapable of identifying recent intake: It typically requires 5-7 days for drugs to become apparent in hair.
• Expense: Hair drug assessments are often more costly than other drug analysis methods.
• Discrepancies in outcomes: Elements such as hair color and individual disparities in hair growth may influence the concentration of drug residues in the hair.

Note: Despite being colloquially termed as "hair follicle tests", the evaluation actually analyzes the hair strand and does not encompass the hair follicle beneath the scalp.
