Located in Fort Lewis, Washington, Accredited Drug Testing provides comprehensive hair follicle drug testing services. When you require a hair or alcohol analysis, Accredited Drug Testing's specialty in hair testing is accessible through our nationwide centers. Typically, you'll need 1.5 to 2 inches of hair from the crown or body. Our hair tests can detect drugs, alcohol/ETG, and offer specialized options.
Recently, hair follicle drug testing has emerged as a preferred method. Increasingly, employers, courts, and substance abuse experts are opting for hair testing over urine tests. It serves zero-tolerance employers, judicial bodies, and those on probation. The key advantage is its extensive detection period of up to 90 days, having an observed collection making it tough to tamper with. For drug use within the past five days, however, urine tests remain more precise.

Hair analysis has gained recognition as an effective approach to identifying drug and alcohol consumption. Hair offers a comprehensive historical record of drugs and alcohol by embedding biomarkers within the strands' fibers as they grow. When obtained near the scalp, hair can reveal substance use over a span of up to three months. It is straightforward to gather, relatively resistant to tampering, and simple to send for examination.
A specimen of 1.5 inches consisting of approximately 200 hair strands (roughly the width of a #2 pencil) closest to the scalp yields 100mg of hair, which is the optimal sample size for testing and verification. For EtG, additional analyses, or tests exceeding 10 panels, it is advised to use 150mg of the sample. The sample should be weighed using a jeweler’s scale. Should scalp hair not be accessible, an equivalent quantity of body hair can be collected. When referencing head hair, it pertains solely to scalp hair. Body hair encompasses all other types of hair (facial, axillary, etc.).
Process Overview
The laboratory procedure for processing a drug test result consists of four main phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase where a sample is integrated into the laboratory’s system. This involves ensuring the sample is securely sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entries not provided by an electronic chain of custody system.
Screening serves as an initial rapid inspection for substances of abuse. While it is a cost-effective method to dismiss drug usage on most samples, a positive result needs validation to be acceptable in legal settings. Samples that test presumptively positive in Screening need a subsequent confirmation.
When a sample tests presumptively positive in the Screening phase, additional hair is retrieved from the original sample for Extraction. During this phase, substances are isolated from hair at considerably lower concentrations compared to other methods (like urine or oral fluid), making hair drug screening one of the most complex methodologies.
Confirmation of any positive screening outcomes is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples testing presumptively positive are washed prior to confirmation as necessary. From Accessioning to Confirmation, the entire lab process is scrutinized under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.
