Accredited Drug Testing offers comprehensive hair follicle drug testing in Corona, California. If you're in need of a hair substance test, our expertise lies in hair analysis, available at centers Nationwide. Most tests use 1.5 to 2 inches of hair from the crown or body hair when necessary. Hair samples can detect drugs, alcohol, or provide other tailored testing solutions.
Hair follicle drug testing has grown in popularity among employers, courts, and substance abuse experts, who often prefer it to standard urine tests. This method is valuable for zero-tolerance policies, judicial requirements, and probationers. Its key advantage is detecting drug use over a prolonged period—up to 90 days—through a supervised method, greatly reducing chances of tampering. For detecting recent usage within 5 days, urine tests remain the preferred choice.

Hair analysis is now recognized as an effective means for identifying drug and alcohol consumption. By embedding biomarkers within the fibers of developing hair strands, hair offers an extended timeline of alcohol and other drug use. Collected near the scalp, hair can reveal a detection period of around three months for alcohol and various drugs. It's straightforward to gather, challenging to tamper with, and uncomplicated to transport.
A hair sample measuring 1.5 inches with around 200 strands (approximately the thickness of a #2 pencil) from the scalp provides 100mg, which is perfect for screening and verification. For EtG, additional tests, or those exceeding ten panels, 150mg of the sample is advised. We recommend using a jeweler’s scale to weigh the sample. In the absence of scalp hair, an equivalent amount of body hair is acceptable. When mentioning head hair, we're specifically referring to scalp hair. Body hair encompasses other hair types (such as facial, axillary, etc.).
Process Overview
The key steps in processing a drug test in the lab include Accessioning, Screening, Extraction, and Confirmation stages.
Accessioning is the preliminary step of integrating a sample into a laboratory's system. This involves checking that the sample is securely sealed and properly shipped, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional manual data entry if an electronic chain of custody system is absent.
Screening is a preliminary assessment for addictive substances. Although Screening provides an affordable method for discarding drug use in most samples, a positive Screening necessitates further confirmation to validate its admissibility in legal settings. Any samples showing presumptive positive results in Screening must undergo additional confirmation.
If a sample returns a presumptive positive result during Screening, additional hair is extracted from the initial specimen for Extraction. This phase involves extracting drugs from hair at a significantly lower concentration than that from alternative methodologies (e.g., urine or oral fluid), thus making hair drug testing the most intricate method to execute.
Positive results from Screening undergo Confirmation via GC/MS, GC/MS/MS or LC/MS/MS. Before confirmation, all presumptive positive samples are cleansed as required. From Accessioning to Confirmation, the entire lab process is evaluated under both the CAP (College of American Pathologists) Hair designation along with ISO / IEC 17025 accreditation standards.
