Hair Follicle Drug Testing - Barstow, WA

What it is, How it works

Hair analysis has emerged as a potent method for identifying drug and alcohol consumption. Hair captures a detailed record of substance use by embedding biomarkers within the fibers of its strands. When sampled close to the scalp, hair offers an approximate 3-month detection period for alcohol and other substances. Collecting hair is straightforward, relatively resistant to tampering, and easily transportable.

A 1.5-inch segment of around 200 hair strands (comparable to a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal sample for both screening and confirmation. For EtG, additional panels, or tests exceeding 10 panels, 150mg of hair is suggested. It's advisable to use a jeweler’s scale for specimen weighing. If scalp hair is not available, a comparable amount of body hair can be collected. The term head hair refers only to scalp hair. Body hair encompasses other types (facial, axillary, etc.).

Process Overview

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

During Accessioning, a sample is initially processed into a laboratory’s system. This process verifies proper sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data entry missing from the electronic chain of custody system.

Screening entails a preliminary rapid assessment for drugs of abuse. Although Screening is a cost-efficient method to eliminate drug usage in most samples, a confirmed positive screen is necessary for legal defensibility. Samples presumptively positive in Screening necessitate secondary confirmation.

For samples deemed presumptively positive during the Screening phase, additional hair is extracted from the original specimen for Extraction preparation. During Extraction, drug traces are isolated from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), thus making hair drug screening the most challenging method.

Positive screening results undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples are cleansed as necessary. The entire laboratory process, from Accessioning to Confirmation, complies with both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can trace drug use for up to 90 days, against urine tests which have shorter detection spans.
• Hard to falsify: Cheating on a hair drug test is notably difficult, enhancing result accuracy.
• Shows usage patterns: It provides a timeline of drug use rather than just recent consumption.

Limitations:

• Inability to detect recent usage: Drugs require about 5-7 days to become identifiable in hair.
• Expense: Hair drug tests are typically costlier compared to other testing approaches.
• Results variability: Variations in hair color and individual hair growth rates can impact the drug metabolite concentrations in hair.

Note: Despite often being termed "hair follicle tests", the test actually examines the hair strand rather than the follicle beneath the scalp.
