Accredited Drug Testing offers comprehensive hair follicle drug assessments in Packwood, Washington. If a hair drug or alcohol screening is needed, Accredited Drug Testing excels in this area, with facilities nationwide ready to conduct a hair analysis. Typically, 1.5 to 2 inches of head or body hair are required, and the tests can detect drugs, alcohol/ETG, or other specialized parameters.
Recently, hair follicle drug tests have become more commonly used for drug screening. Employers, judicial systems, and substance abuse experts often prefer them over traditional urine tests. Hair tests appeal to entities with strict drug-free policies, such as courts and probation officers, due to their longer detection window of up to 90 days, meticulous collection process, and resistance to tampering. However, for recent drug use within the past 5 days, urine tests remain superior.

Recognized for its efficacy, hair testing has emerged as a robust method for identifying drug and alcohol consumption. By embedding biomarkers within the fibers of hair strands as they grow, hair retains a detailed history of substance use. When hair is gathered near the scalp, it can indicate use of alcohol and drugs for an approximate period of up to three months. This method of testing is straightforward to administer, challenging to tamper with, and convenient to transport.
A sample of 1.5 inches from about 200 hair strands, akin to the thickness of a #2 pencil, collected from the scalp, represents an optimum sample of 100mg for screening and confirmative purposes. For EtG, additional analyses, and/or panel tests exceeding ten, a 150mg sample is advised. Utilizing a jeweler’s scale for measuring the specimen is recommended. If scalp hair isn't accessible, a comparable volume of body hair may be used instead. References to head hair pertain specifically to scalp hair. Conversely, body hair encompasses facial and axillary hair, among others.
Process Overview
The laboratory procedures for processing drug test results encompass four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning constitutes the initial phase where the sample is introduced to the laboratory's system. This stage confirms that the sample has been appropriately sealed and shipped, assigns it a unique LAN (Laboratory Accessioning Number), and finalizes any additional data entry not supplied by an electronic chain of custody system.
Screening acts as a preliminary assessment for the presence of drugs. As a cost-efficient measure, Screening helps exclude drug presence in most samples, but any positive result from this stage requires confirmation for legal validity. Any samples returning presumptively positive results in Screening necessitate subsequent confirmation.
Should Screening identify a sample as presumptively positive, further hair is extracted from the original sample for the Extraction phase. During Extraction, substances are isolated from hair at significantly lower concentrations than seen in urine or saliva tests, contributing to the complexity of hair drug screening.
Confirmed positive Screening results undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptive positive samples undergo necessary washing prior to Confirmation. The laboratory procedure from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair classification and aligned with ISO / IEC 17025 accreditation standards.
