Accredited Drug Testing offers comprehensive hair follicle drug assessments throughout Richland, Washington. For those requiring hair or alcohol tests, we specialize in this field, with establishments spanning across the nation to facilitate hair examinations. Generally, 1.5 to 2 inches of hair on the head or body is needed for testing. Our analyses can detect drugs, alcohol/ETG, and other customized options.
Recently, drug tests increasingly incorporate hair follicle methods. Employers, judicial systems, and Substance Abuse experts prefer hair tests over traditional urine tests. This method is favored by employers with strict anti-drug policies, courts, and probation services. Its main advantage is the extended 90-day detection period, observed sample collection, and difficulty in tampering. Still, urine tests remain the most precise within the first 5 days of drug use.

The assessment of hair as an investigative instrument for detecting substance and alcohol intake has gained recognition. By trapping biomarkers into the fibers, hair records a prolonged chronicle of drug and alcohol usage. When gathered near the scalp, it offers a detection span of about three months for substances and alcohol. Collecting hair is straightforward, challenging to tamper with, and uncomplicated to transport.
A sample of 1.5 inches, nearly 200 hair strands (roughly akin to the width of a #2 pencil) from the closest to the scalp produces 100mg, which serves as the optimal sample for both screening and confirmation. For EtG, additional tests, or beyond 10-panel screenings, it is advisable to obtain 150mg of the sample. Using a jeweler’s scale for weighing the specimen is recommended. Should scalp hair not be accessible, an equivalent volume of body hair can be utilized. References to head hair particularly denote scalp hair only. Body hair encompasses all other types, including facial and axillary hair.
Process Overview
Laboratory processing for drug test results follows four primary stages: Accessioning, Screening, Extraction, and Confirmation.
The first phase, Accessioning, involves incorporating the sample into a laboratory’s system, verifying proper sealing and shipment, assigning a randomized LAN (Laboratory Accessioning Number), and completing outstanding data not addressed by an e-chain of custody framework.
Screening commences with a swift assessment for drug traces. While it's a cost-efficient method to eliminate drug presence in most samples, courtroom admissibility requires that any positive Screening findings undergo confirmation. Presumptive positive results in Screening necessitate a secondary verification.
In cases of a presumptive positive from the Screening phase, additional hair from the original sample undergoes preparation for Extraction. Herein drugs are extracted from hair at significantly lower levels compared to alternative methods like urine or oral fluid testing, underscoring the complexity of performing hair drug screenings.
Confirming positive Screening outcomes is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. Samples indicated as presumptive positives are washed before confirmation as required. The complete laboratory procedure, from Accessioning to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair guidelines and conforms to ISO / IEC 17025 accreditation standards.
