Accredited Drug Testing provides thorough hair follicle drug testing services in Lafayette, Oregon. If you're in need of such tests for drugs or alcohol, Accredited Drug Testing is an expert in this area, with test centers available across all U.S. cities. Typically, tests require 1.5 to 2 inches of hair, taken from the crown or body. These tests can detect drugs, alcohol/ETG, or offer additional tailored testing options.
Recently, hair follicle drug tests have become a more popular method for substance testing. Employers, judiciary bodies, and substance abuse experts favor this type of test over the classic urine test. Employers with strict drug policies, legal professionals, and probationers often utilize these tests. A key advantage is the extended detection window of up to 90 days, via supervised collection, making it nearly tamper-proof. However, urine tests remain best for detecting recent drug use within 5 days.

Hair analysis is now recognized as an influential method for identifying substance and alcohol consumption. Hair captures and retains biomarkers of these substances within its fibers, offering a historical timeline of use. When taken near the scalp, hair samples can indicate drug or alcohol presence over a span of up to 90 days. Collection of hair samples is straightforward, tampering is challenging, and shipping is uncomplicated.
A hair sample measuring 1.5 inches and comprising roughly 200 strands near the scalp will weigh approximately 100mg, which is the optimal quantity for both screening and confirming. For EtG, additional tests, or procedures exceeding 10 panels, a sample size of 150mg is advisable. It's beneficial to measure the sample using a jeweler’s scale. Should scalp hair be unavailable, equivalent body hair can be used. References to head hair pertain specifically to scalp hair, whereas body hair includes all other types (facial, axillary, etc.).
Process Summary
Processing a drug test result in the lab consists of four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase where the sample is incorporated into the lab's system, which involves verifying proper sealing and shipment, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional manual data entry not captured electronically.
Screening is a preliminary, rapid assessment for the presence of drugs. Though economical for ruling out drug use in most samples, a positive screen requires further confirmation for legal acceptability. Any samples showing presumptive positivity in Screening necessitate secondary confirmation.
Should a sample test presumptively positive during Screening, additional hair is extracted for the Extraction stage. Here, substances are isolated from hair at significantly lower concentrations than other procedures (e.g., urine or oral fluid tests), making hair drug screening the most complex process to execute.
Confirmation of positive screening results employs GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples undergo washing before final confirmation if needed. The full lab process from Accessioning through Confirmation undergoes scrutiny under the guidelines of CAP (College of American Pathologists) Hair designation and is aligned with ISO / IEC 17025 standards.
