Accredited Drug Testing offers comprehensive hair follicle testing in Dixon, CA. Our specialty in hair drug and alcohol tests is backed by a network of centers across all cities Nationwide ready to conduct hair tests. Generally, 1.5 to 2 inches of hair from the crown or body can be used. Hair tests are available for drugs, alcohol/ETG, or other bespoke analyses.
The trend in drug testing has seen a rise in the use of hair follicle tests over urine tests. Employers, courts, and Substance Abuse experts increasingly prefer hair tests for their rigorous no-drug policies. The foremost advantage of hair testing is its extensive detection window of up to 90 days, collected under presentation, and difficult to tamper with. Yet, for drug use screening within the last 5 days, urine tests remain most accurate.

Hair analysis has emerged as an effective tool for detecting drug and alcohol consumption. By encasing biomarkers within the fibers of the hair strand as it grows, hair offers a long-term record of alcohol and other drug use. Collected near the scalp, hair can reveal up to around a 3-month window for detecting alcohol and other drugs. Hair is easy to collect, challenging to adulterate, and simple to transport.
A 1.5-inch section consisting of roughly 200 hair strands (comparable to a #2 pencil) nearest to the scalp provides 100mg of hair, the optimal sample size for screening and corroboration. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the sample is advised. We suggest weighing the sample using a jeweler’s scale. If scalp hair is not available, an equivalent amount of body hair may be obtained. When mentioning head hair, we refer exclusively to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial handling of a sample into the lab’s system. This step verifies that the sample was correctly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data entry not covered by an electronic chain of custody system.
Screening provides an initial quick assessment for drugs of abuse. While Screening is a cost-efficient way to eliminate drug use for most samples, a positive screen must be validated for court admissibility. Any samples that appear positive in Screening require a secondary confirmation.
For samples that appear positive in the Screening phase, more hair is extracted from the initial sample and readied for Extraction. In this step, drugs are extracted from hair at much lower concentrations compared to other methodologies (e.g., urine or oral fluid), hence why hair drug screening is one of the most challenging methods to perform.
Confirmation for any positive screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that suggest positive results are washed before confirmation if necessary. The comprehensive laboratory process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair specification and the accreditation to ISO / IEC 17025 standards.
