Accredited Drug Testing provides comprehensive hair follicle drug examinations in Tuolumne City, California. If a hair or alcohol drug test is needed, Accredited Drug Testing excels in hair assessment, offering facilities across all cities nationwide for hair testing. Typically, 1.5 to 2 inches of hair from the crown or body can be utilized. Hair tests can be tailored to detect drugs, alcohol/ETG, or other specific needs.
Lately, the method of drug testing has increasingly leaned towards a hair follicle analysis. Many businesses, legal entities, and Substance Abuse experts now favor hair drug tests over traditional urine analysis. Employers enforcing zero-tolerance drug policies, courts, and probation officers commonly employ hair follicle tests. Their key advantage is detecting drug use over a longer window, often up to 90 days, through an observed collection method, making tampering almost impossible. For drug use under five days, urine tests remain the most precise option.

The use of hair testing has gained recognition as an effective measure for identifying the consumption of drugs and alcohol. By embedding biomarkers within the fibers of a growing hair strand, hair can chronicle a substantial history of alcohol and drug intake. When taken near the scalp, it offers a detection period of up to roughly three months for tracing both alcohol and drugs. Collecting hair is straightforward, challenging to tamper with, and convenient for shipping.
A 1.5-inch lock comprising around 200 strands of hair (similar in size to a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal sample for initial testing and follow-up confirmation. For tests like EtG, additional panels, or exceeding 10 panels, 150mg of the specimen is suggested. We advise measuring the sample using a jeweler’s scale. Should scalp hair be unattainable, an equivalent volume of body hair could be substituted. When mention is made of head hair, it is exclusive to scalp hair. Body hair includes all other categories of hair (facial, axillary, etc.).
Process Overview
The laboratory procedure for processing a drug test outcome encompasses four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of the primary handling of an incoming sample within a laboratory framework. This step ensures the sample was correctly sealed and dispatched, allocates a unique LAN (Laboratory Accessioning Number), and concludes any supplementary data inputs not handled by an electronic chain of custody system.
Screening executes a preliminary rapid assessment for substance misuse. Though Screening provides a cost-efficient means to negate drug presence in most samples, a positive result during Screening mandates confirmation for legal acceptance. Samples that show potential positives during Screening necessitate additional verification.
Should a sample show a preliminary positive at the Screening stage, extra hair is extracted from the original specimen to prepare for Extraction. This phase involves retrieving drugs from hair at notably lower concentrations than other techniques (such as urine or oral fluid), highlighting the challenge of performing hair drug screening.
Confirmation of any presumptive positive result is achieved through GC/MS, GC/MS/MS, or LC/MS/MS methods. Samples assigned presumptive positives undergo necessary washing prior to confirmation. The full laboratory process from Accessioning to Confirmation is carried out under the scrutiny of both the CAP (College of American Pathologists) Hair certification and the ISO / IEC 17025 standards.
