Accredited Drug Testing provides comprehensive hair follicle drug testing in Chehalis Village, Washington. Whether you require a hair test for drugs or alcohol, Accredited Drug Testing offers specialized hair testing services. With testing centers in every city nationwide, we can conduct hair tests efficiently. Generally, 1.5 to 2 inches of hair from your head or body hair is needed. Hair tests can be customized for drug, alcohol/ETG, or other analyses.
In the past few years, the approach to drug testing increasingly favors hair follicle drug tests. Various employers, courts, and Substance Abuse experts now demand a hair drug test over the standard urine test. These tests are valued by employers with zero-tolerance drug policies, courts, and probation officers. The significant advantage of hair follicle tests is the extended detection period for drug use, typically up to 90 days, acquired through observed collection, making it nearly impossible to manipulate. However, for detecting drug use in the past five days, urine tests remain highly accurate.

Hair analysis is recognized as a significant method for identifying substance and alcohol consumption. Hair encases historical data on both alcohol and drugs by embedding biomarkers within the strands. Obtaining hair samples near the scalp allows for a detection timeframe of up to roughly three months for substances. The process of collecting hair is straightforward, it resists tampering, and shipping is uncomplicated.
A sample measuring 1.5 inches and containing around 200 hair strands (comparable to a #2 pencil's thickness) from near the scalp yields 100mg, the ideal quantity for testing. For EtG, additional tests, or those beyond 10 panels, a 150mg sample is advisable. We suggest using a jeweler's scale for measuring. If scalp hair is absent, collecting an equivalent bulk of body hair suffices. "Head hair" denotes scalp strands; in contrast, "body hair" encompasses facial, axillary, and other types.
Process Overview
The sequence of steps in lab processing for a drug test result comprises Accessioning, Screening, Extraction, and Confirmation.
Accessioning introduces the sample into a lab's system. This phase checks the sample's proper sealing and shipping, assigns a LAN (Laboratory Accessioning Number), and finalizes any pending data entry not captured by an electronic chain of custody system.
Screening provides an initial, rapid assessment for drugs. While cost-efficient for eliminating drug use in most samples, a positive screening requires confirmation for legal acceptance. All presumed positive results during Screening need further validation.
When a presumed positive arises from Screening, additional hair is collected from the primary sample for Extraction. In this phase, substances are extracted from hair at much lower concentrations than other methods (e.g., urine or oral fluids), increasing the complexity of hair drug testing.
Confirmation of any positive screening is performed through GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumed positives are washed if necessary. Each lab process, from Accessioning to Confirmation, undergoes review by CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
