Accredited Drug Testing offers full hair follicle drug testing services in Vallejo, California. We provide specialized hair tests for both drugs and alcohol, with facilities available in various cities across the nation to carry out these tests. Generally, 1.5 to 2 inches of hair from your head or body is needed. Hair testing can be tailored to check for drugs, alcohol/ETG, or other specific requirements.
The adoption of hair follicle drug testing methods has been on the rise, particularly among employers, courts, and Substance Abuse professionals, who favor it over traditional urine testing. This method is ideal for businesses with stringent drug-free policies, legal authorities, and for probationary purposes. Its main advantage is the extensive detection window, lasting up to 90 days. The collection process is observed, which makes tampering nearly impossible. Nevertheless, for detecting very recent drug usage, within five days, urine tests are still considered optimal.

Hair analysis is increasingly recognized as an effective means for detecting drug and alcohol use. The hair locks in biomarkers along the fibers of its elongating strand, providing a prolonged snapshot of alcohol and drug consumption. When samples are gathered near the scalp, hair can offer an approximate 3-month window for detecting alcohol and drugs. The procedure for gathering hair is straightforward, it’s relatively challenging to tamper with, and it’s convenient for shipping.
A specimen length of 1.5 inches comprising roughly 200 hair strands (similar in thickness to a #2 pencil) nearest the scalp offers 100mg of hair, which is optimal for both screening and verification. For EtG, additional analyses, and tests exceeding 10 panels, 150mg of the sample is advised. We suggest utilizing a jeweler’s scale for measuring the specimen. Should scalp hair be unavailable, an equivalent quantity of body hair can be used. When we mention head hair, we specifically refer to scalp hair. Body hair encompasses all other hair forms (like facial, axillary, etc.).
Process Overview
The key stages of the lab processing for drug test outcomes are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the primary handling of a sample into a laboratory's database. This step ensures the sample was correctly sealed and transported, allocates a unique LAN (Laboratory Accessioning Number), and completes any leftover data entry not available through an electronic chain of custody system.
Screening is an initial, swift analysis for drugs of misuse. Although Screening offers an economical means to eliminate drug use on most specimens, a positive result must be validated before it can be legally recognized. Samples showing presumptive positive results in Screening necessitate additional confirmation.
In cases where a sample shows a presumptive positive in Screening, additional hair is drawn from the initial sample for Extraction. In this process, drugs are extracted from hair at much lower concentrations compared to other techniques (such as urine or oral fluid), rendering hair drug screening a challenging method to conduct.
The verification of any positive result in Screening involves GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive specimens are cleansed before confirmation as necessary. This complete laboratory process—from Accessioning through Confirmation—is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.
