Hair Follicle Drug Testing - Fall City, WA

What it is, How it works

Hair analysis has emerged as a potent method for identifying drug and alcohol consumption. Hair captures a long-term record of drug and alcohol use by embedding biomarkers in the strands of the growing hair. When collected near the scalp, hair can showcase up to a three-month window for detecting alcohol and drugs. It is easy to collect, challenging to tamper with, and convenient to transport.

A 1.5-inch sample, roughly the size of a #2 pencil, with around 200 strands of hair nearest to the scalp, offers 100mg of hair, which is the optimal sample for both screening and confirmation. For EtG, supplemental panels, and/or tests exceeding 10 panels, a 150mg sample is advised. It is advisable to weigh the sample using a jeweler's scale. If scalp hair is not an option, the same quantity of body hair may be used. "Head hair" implies scalp hair only, while "body hair" encompasses all other hair types, such as facial and axillary.

Process Overview

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

Accessioning entails the preliminary handling of a specimen within a lab system. This step checks that the sample is properly sealed and shipped, assigns a unique LAN (Laboratory Accessioning Number), and completes any required data entry omitted by an electronic chain of custody system.

Screening is a preliminary assessment to detect drugs of abuse. Although Screening is a budget-friendly means to rule out drug consumption in most samples, a positive result necessitates confirmation for court admissibility. Any samples presumed positive in Screening require an additional confirmation step.

When a sample tests presumptively positive during Screening, additional hair is taken from the original sample and readied for Extraction. In Extraction, drugs are isolated from hair at a much lower concentration than other methods (e.g., urine or saliva), making hair drug testing one of the most daunting methodologies.

Confirmation of a positive screen is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumed positive samples undergo washing prior to confirmation as required. The complete lab workflow from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair guidelines and the accreditation per ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can discern drug intake for up to 90 days, unlike urine tests which have a reduced detection timeframe.
• Challenging to deceive: Hair drug tests are very difficult to game, resulting in more reliable outcomes.
• Delivers historical insights: Hair tests can exhibit a trend of drug usage over time, rather than just recent activity.

Limitations:

• Cannot identify recent use: It requires approximately 5-7 days for drugs to become traceable in hair.
• Expense: Hair drug tests are typically costlier compared to other testing techniques.
• Variable outcomes: Aspects such as hair color and personal discrepancies in hair growth can influence the level of drug metabolites in the hair.

Note: Though commonly called "hair follicle tests", the examination targets the hair strand itself, not the follicle beneath the scalp.
