Accredited Drug Testing offers comprehensive hair follicle drug testing services in Redmond, Washington. If a hair or alcohol drug test is required, Accredited Drug Testing is a specialist in hair analysis, with centers across all cities nationwide that can execute a hair test. Usually, 1.5 to 2 inches of hair from the crown or body is necessary. Hair testing can identify drugs, alcohol/ETG, and other tailored testing options.
Recently, drug testing protocols increasingly feature hair follicle drug tests. Numerous employers, judicial systems, and Substance Abuse experts prefer hair over urine testing. Employers enforcing zero-tolerance drug policies, courthouses, and probation-bound individuals employ hair follicle drug tests. Its main advantage is the extended detection window for drugs, usually up to 90 days, gathered in an observed manner, making it largely tamper-proof. Nevertheless, urine tests remain superior for identifying drug use within the prior 5 days.

When you're searching for hair drug testing near me or hair drug testing locations, we provide a simple and convenient process to find a drug and alcohol testing location near you that is certified to provide all of your drug and alcohol testing needs.
Recognized for its effectiveness, hair testing is a valuable strategy for identifying substance use, holding biomarkers within the hair's growth that reveal historical drug and alcohol patterns. When hair is gathered near the scalp, it offers a detection range extending up to roughly three months for substances. Collecting hair is straightforward, challenging to tamper with, and uncomplicated to transport.
To obtain an adequate sample, a hair strand section of 1.5 inches containing approximately 200 hairs (similar in size to a standard #2 pencil) near the scalp provides 100mg of hair, ideal for both screening and confirmation processes. For EtG analysis and detailed testing extending beyond 10 panels, 150mg of the sample is advised. Utilizing a jeweler’s scale to weigh the sample is recommended. Should scalp hair not be available, a comparable quantity of body hair can be used. When discussing head hair, we refer solely to scalp hair. Conversely, body hair encompasses all other hair types (including facial and axillary).
Process Overview
The laboratory processing of a drug test result encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves integrating a specimen into a lab's system initially. This phase ensures the sample's proper sealing and shipment, assigns a random LAN (Laboratory Accessioning Number), and finalizes any requisite data entry absent an electronic chain of custody system.
Screening represents an initial assessment for substance misuse. It's a cost-efficient approach for excluding drug presence across many cases, though positives from screening necessitate confirmation for legal validity. Any samples indicating presumptive positives in Screening mandate further confirmation.
Should a sample show a presumptive positive in the Screening phase, additional hair from the original sample undergoes preparation for Extraction. In this step, substances are extracted from hair at significantly lower concentrations than found in alternative methods (such as urine or oral fluid), making hair drug screening a particularly complex process to execute.
Positive screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS methods. All samples indicating presumptive positivity are cleansed before confirmation if required. The entire procedural pathway, from Accessioning through to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair criteria and accreditation to ISO / IEC 17025 standards.

Note: Although commonly called "hair follicle tests," the analysis focuses on the hair strand itself, not the follicle beneath the scalp.
