Accredited Drug Testing provides comprehensive hair follicle drug assessments in Preston, Washington. If you require a drug or alcohol analysis using hair samples, Accredited Drug Testing excels in this area, featuring testing sites in every city across the USA capable of conducting hair tests. Typically, 1.5 to 2 inches of hair from the head or body is needed. Hair evaluations can detect drugs, alcohol/ETG, or other tailored testing options.
In recent times, hair follicle drug assessments have been increasingly adopted as a preferred testing method. Employers, legal systems, and support specialists in substance abuse are opting for hair drug evaluations instead of conventional urine tests. Hair follicle drug assessments are vital for employers with strict no-drug policies, courts, and individuals on probation. The primary advantage is the extended detection window of up to 90 days, collected with observation, making tampering nearly impossible. However, for detection within the past 5 days, urine testing remains the most accurate.

Hair testing is increasingly recognized as an effective method for detecting drug and alcohol usage. Hair encases biomarkers within the fibers of the growing strand, offering a long-term history of consumption. Collected near the scalp, it can reveal up to an approximately 90-day detection period for substances. It's straightforward to collect, challenging to tamper with, and convenient to transport.
Sampling 1.5 inches of about 200 hair strands (equivalent to the thickness of a #2 pencil) near the scalp yields 100mg, which is the optimal quantity for both screening and confirmation. For EtG, additional testing, and/or more than 10 panels, 150mg is advised. It's suggested to weigh the specimen using a jeweler’s scale. Should scalp hair be unavailable, a similar volume of body hair can be used. Here, head hair specifies scalp hair solely, whereas body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The key steps in processing a drug test in the lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the sample's initial processing into a lab’s system, confirming the sample's proper seal and shipment, assigning a random LAN (Laboratory Accessioning Number), and performing any additional non-electronic chain of custody data entry.
Screening performs a preliminary check for drugs of abuse. It's a cost-effective method to exclude drug use in most cases; however, a positive screen necessitates confirmation to be legally used. Any presumptive positive results in Screening must undergo further confirmation.
When a sample tests presumptively positive during Screening, additional hair is extracted from the initial sample and prepared for Extraction. This phase pulls drugs from hair in concentrations significantly lower than those in other methods (e.g., urine or oral fluid), making hair drug testing the most complex method to execute.
Confirmation of any positive Screening result is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. Samples testing presumptively positive are cleansed before confirmation as required. The entire lab process from Accessioning to Confirmation adheres to rigorous standards, including those of the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.
