Hair Follicle Drug Testing - Annex, OR

What it is, How it works

Hair analysis has emerged as an effective means for identifying drug and alcohol consumption. Hair strands preserve a long-term record of alcohol and drug use by embedding biomarkers within the growing strand. When collected near the scalp, hair can reveal usage patterns for up to three months. Collecting hair is straightforward, challenging to tamper with, and convenient for transport.

A 1.5-inch section comprising roughly 200 hair strands (approximating the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, the preferred quantity for testing and verification. For EtG, additional screenings, or tests exceeding 10 panels, 150mg is advisable. Using a jeweler’s scale for precise measurement is suggested. If scalp hair is inaccessible, an equivalent quantity of body hair may be utilized. References to head hair pertain solely to scalp hair. Body hair encompasses all other hair forms (facial, axillary, etc.).

Process Overview

The core stages in processing a drug test result within a laboratory include Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial registration of a sample into a laboratory's system. This step confirms that the sample was adequately sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and concludes any additional data logging not covered by an electronic chain of custody system.

Screening serves as an initial rapid assessment for drug misuse. Although cost-efficient for excluding drug use in most samples, a positive screen necessitates confirmation for legal admissibility. Samples that show presumptive positivity during Screening require further validation.

For samples with presumptive positivity in the Screening phase, additional hair is extracted from the original specimen and prepped for Extraction. Here, drugs are isolated from hair at significantly lower concentrations than in methods like urine or oral fluid, making hair drug testing particularly arduous.

Positive screening confirmations are executed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation as needed. The entire lab procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug assessments can trace drug use up to 90 days, surpassing urine tests with shorter windows.
• Hard to manipulate: Cheating a hair drug test is exceptionally hard, ensuring accurate findings.
• Delivers longitudinal data: Offers a record of drug use over time, beyond just recent activity.

Limitations:

• Inability to detect recent usage: Detectability of drugs in hair takes about 5-7 days.
• Expense: Generally, hair drug tests cost more than other testing forms.
• Result variations: Factors like hair color and individual hair growth differences can influence drug metabolite concentration in hair.

Note: Although often termed "hair follicle tests", the examination targets the hair strand, not the underlying follicle.
