Accredited Drug Testing offers comprehensive hair follicle drug tests in Vineyard, California. For those needing a hair or alcohol assessment, we're experts in hair analysis. Our nationwide centers, located in all cities, are equipped to conduct these tests. Typically, 1.5 to 2 inches of hair from the crown or body is needed. Hair tests can screen for drugs, alcohol/ETG, or be tailored for other specific testing.
Recently, drug testing methods increasingly favor hair follicle tests. Employers, courts, and Substance Abuse experts often prefer them over standard urine tests. These tests support zero-tolerance policies and are used for probation assessments. The main advantage is a longer detection window, up to 90 days, performed under supervision, making it nearly impossible to tamper with. However, for recent drug use within 5 days, urine tests remain the most accurate.

Hair testing is widely recognized as an effective method for identifying drug and alcohol consumption. By incorporating biomarkers into the fibers of growing hair, hair retains a comprehensive history of substance use. When samples are taken close to the scalp, they can reveal up to a 3-month detection window for alcohol and other drug markers. The collection process for hair is straightforward, challenging to tamper with, and convenient to transport.
Collecting a 1.5-inch segment of around 200 hair strands (similar in size to a #2 pencil) nearest to the scalp yields approximately 100mg of hair, presenting an ideal quantity for both screening and confirmation tests. For extended tests such as EtG add-ons or panels exceeding 10, a specimen weight of 150mg is suggested. We recommend using a jeweler’s scale to confirm the specimen's weight. Should scalp hair be inaccessible, a comparable amount of hair from the body can be used. When mentioning head hair, we specifically refer to scalp hair, whereas body hair encompasses other forms of hair such as facial and axillary.
Process Overview
The core phases in the laboratory processing of a drug testing sample include Accessioning, Screening, Extraction, and Confirmation.
Accessioning initiates the study by incorporating the sample into the laboratory’s system. This step confirms cargo integrity, assigns a random LAN (Laboratory Accessioning Number), and performs any necessary data entry missing from electronic chain of custody systems.
Screening performs a general analysis to detect drug presence. Though cost-effective for dismissing potential drug use in most specimens, a positive result from this phase requires confirmation for forensic validity. Samples marked presumptively positive in Screening proceed to a confirmatory phase.
Presumptive positives from the Screening phase undergo additional testing via further hair extraction. During this phase, drugs are isolated from hair at much finer concentrations than other methods (such as urine or oral fluid), emphasizing why hair drug testing is considered the most challenging methodology.
Confirmed positive screening results utilize GC/MS, GC/MS/MS, or LC/MS/MS methods. Prior to final verification, presumptive positive samples may be cleansed as necessary. The complete laboratory sequence, from Accessioning to Confirmation, is scrutinized according to both CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation standards.
