Accredited Drug Testing offers exhaustive hair follicle drug testing services in Edmonds, Washington. When in need of a hair or alcohol test, Accredited Drug Testing focuses on hair testing, with locations available across all cities nationwide to conduct these tests. Typically, 1.5 to 2 inches of hair from the crown or body is required. Hair analyses can detect drugs, alcohol/ETG, or be customized for other tests.
Lately, drug testing methodologies have shifted towards including more hair follicle tests. Many employers, courts, and substance abuse specialists prefer hair drug tests over standard urine tests. Employers enforcing zero-tolerance drug policies, courts, and those on probation frequently use these tests. The key advantage is the extended detection period—up to 90 days, observed during collection, and highly tamper-resistant. However, urine tests remain best for detecting drug use within the last 5 days.

Hair analysis has emerged as a potent method for identifying drug and alcohol consumption. It offers a comprehensive timeline of substance use by capturing biomarkers in the growing hair's fibers. When taken near the scalp, hair can reveal a detection period for alcohol and drugs of up to three months. Hair collection is straightforward, challenging to tamper with, and convenient to transport.
A 1.5-inch section consisting of approximately 200 hair strands (comparable to the size of a #2 pencil) close to the scalp yields 100mg of hair, which is the optimal quantity for both screening and confirmation. For EtG, additional substances, and/or tests exceeding 10 panels, a specimen weighing 150mg is advised. It is suggested to use a jeweler’s scale for weighing. If scalp hair is not accessible, a similar volume of body hair may be used. Head hair refers only to scalp hair. Body hair encompasses all other hair types (such as facial and axillary).
Process Overview
The four primary procedures in laboratory processing of a drug test outcome encompass Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary processing of a sample into a laboratory’s system. This step ensures the sample was properly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data entry missing from an electronic chain of custody system.
Screening provides a basic evaluation for drugs of abuse. While this is a cost-effective method to rule out drug usage in most samples, a confirmed positive screen is required for legal acceptability. Any samples presumed positive during Screening must undergo a secondary confirmation.
For samples presumed positive during the Screening phase, additional hair is extracted from the initial sample and prepped for Extraction. Drugs are extracted in this phase at lower concentrations than other methods (such as urine or oral fluid), which makes hair drug screening one of the most complex methodologies.
Confirmation of positive screens is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as necessary. The entire laboratory process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation.
