Accredited Drug Testing provides comprehensive hair follicle drug assessments in Groveland, California. If a hair drug or alcohol test is necessary, Accredited Drug Testing excels in this method, with centers located Nationwide ready to conduct them. A typical requirement is 1.5 to 2 inches of hair on the head or body. Hair analysis can detect drugs, alcohol/ETG, or offer tailor-made hair testing solutions.
In the past few years, drug testing methods have leaned more toward hair follicle drug assessments. Many businesses, judicial systems, and addiction specialists prefer hair tests over the conventional urine samples. Hair follicle tests are utilized by employers with strict anti-drug-use stances, courts, and probationers. A key advantage of hair tests is a longer detection window—up to 90 days—ensuring nearly foolproof testing. Nevertheless, for the most recent 5-day drug use, urine testing still holds superior accuracy.

Hair analysis has emerged as an effective method for detecting substance intake. Hair encapsulates biomarkers within its fibers as it grows, offering an extended history of alcohol and drug usage. When hair is cut near the scalp, it can reveal evidence of drug and alcohol consumption for up to around 3 months. Collecting hair samples is straightforward, challenging to tamper with, and convenient to transport.
A 1.5-inch section comprising roughly 200 hair strands (approximately the thickness of a #2 pencil) taken from the scalp provides 100mg of hair, which is the optimal sample size for tests. For EtG, additional analyses, or tests exceeding 10 panels, a 150mg sample is advised. It is recommended to weigh the sample using a jeweler's scale. If scalp hair cannot be obtained, a comparable quantity of body hair may be used. The term "head hair" specifically refers to scalp hair, while "body hair" includes all other hair types, such as facial and axillary hair.
Process Overview
The laboratory stages for processing a drug test include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of integrating a sample into a lab’s system. This step ensures the sample was sealed correctly, assigns a unique LAN (Laboratory Accessioning Number), and completes any further data entry not handled by an electronic chain of custody.
Screening conducts a swift preliminary analysis for common drugs. Although Screening is cost-efficient for excluding drugs in most samples, a positive Screen necessitates confirmation to be viable for legal proceedings. Samples with a preliminary positive in Screening require additional testing for confirmation.
If Screening suggests a positive result, more hair is extracted from the original sample for further testing in the Extraction phase. During this phase, drugs are extracted from hair at much lower concentrations than other methods (e.g., urine or oral fluid), which makes hair drug testing one of the most challenging methods to execute.
Confirmation of any initial positive outcome occurs via GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all samples with presumptive positives are washed as needed. The lab process from Accessioning to Confirmation adheres to CAP (College of American Pathologists) Hair standards and ISO/IEC 17025 accreditation.
