Accredited Drug Testing offers comprehensive hair follicle drug testing in Dieringer, Washington. For those needing a hair drug or alcohol test, we are experts in this area and provide testing at centers across the nation, including all cities. Generally, you need 1.5 to 2 inches of hair from the crown of your head, but body hair might suffice. Hair tests can be customized for drugs, alcohol/ETG, and other specific requirements.
In recent times, drug testing often involves the hair follicle method. Hair drug tests are increasingly preferred by employers, legal authorities, and substance abuse experts over the conventional urine tests. Employers with strict drug policies, courts, and probationary officers favor this approach. The key advantage is its extended detection window, often up to 90 days, ensured by observed sample collection, making it nearly foolproof. Nonetheless, for identifying drug use within the past 5 days, urine tests remain the gold standard.
* You must register by phone or online to receive your donor pass/registration prior to proceeding to the testing center. You must bring a valid government issued ID along with the registration/barcode number which was sent to you by email.

The utilization of hair testing has gained recognition as an effective method for identifying drug and alcohol consumption. Hair serves as a repository for long-term usage history by embedding biomarkers within its fibers as the strand grows. When gathered from near the scalp, hair can reveal alcohol and drug consumption within an approximate three-month period. The process of collecting hair is straightforward, relatively tamper-proof, and straightforward to transport.
A 1.5-inch segment containing about 200 hair strands (similar in size to a #2 pencil) located closest to the scalp will yield 100mg of hair, which is the optimal amount for both screening and confirmation. For extended tests such as EtG or those exceeding 10 panels, a 150mg sample is advisable. It's suggested to measure the sample using a jeweler's scale. If scalp hair is not an option, a comparable volume of body hair can be used. Head hair refers exclusively to scalp hair, while body hair encompasses all other types (including facial and axillary).
Process Overview
The drug test analysis in the laboratory involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage where a sample is entered into a laboratory's system. This stage involves ensuring the sample was correctly sealed and delivered, generating a random LAN (Laboratory Accessioning Number), and completing any additional input that isn't captured by an electronic chain of custody.
Screening includes an initial abbreviated evaluation to identify drugs of abuse. This step is an economical approach to dismiss drug usage in most samples, although a positive result must undergo confirmation to be legally admissible. Samples with a presumptive positive result in Screening require further confirmation.
If a sample is presumed positive during the Screening step, additional hair is extracted from the initial sample to prepare for Extraction. Here, drugs are retrieved from hair at much lower concentrations when compared to other techniques (such as urine or oral fluid), which contributes to the complexity of hair drug screening.
Any positive screening results undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples are washed as necessary. The entire laboratory testing protocol, from Accessioning to Confirmation, is conducted under the supervision of the CAP (College of American Pathologists) Hair category and accredited to ISO / IEC 17025 standards.
