Accredited Drug Testing administers comprehensive hair follicle drug assessments in Foster City, California. If a hair drug or alcohol evaluation is needed, Accredited Drug Testing is your expert resource. We operate testing facilities in cities nationwide that can carry out a hair test. Typically, 1.5 to 2 inches of hair from your head or body is required. Hair assays can be scrutinized for drugs, alcohol/ETG, or other tailored testing options.
In the past few years, conducting drug evaluations has increasingly involved hair follicle drug assessments. Many employers, judicial systems, and Substance Abuse experts are opting for a hair test over a traditional urine analysis. Hair follicle tests are utilized by businesses with zero-tolerance policies, judicial bodies, and probation-listed individuals. The key advantage of a hair test is its extended detection timeframe of up to 90 days, acquired through an observed process, rendering cheating nearly impossible. However, when inspecting drug use within the past 5 days, urine remains the most precise examination.

Hair testing is recognized as a valuable method for identifying drug and alcohol consumption. Hair strands record long-term evidence of alcohol and drug use by encasing biomarkers within their fibers. When obtained from near the scalp, hair offers around a 3-month detection period for substances. Hair is easy to gather, relatively tamper-resistant, and convenient to transport.
A 1.5-inch segment of about 200 hair strands (roughly pencil-sized) nearest to the scalp yields 100mg, the optimal amount for testing and verification. For EtG, additions, and/or tests over 10 panels, 150mg of hair is advisable. We suggest using a jeweler's scale to weigh the specimen. If scalp hair is not available, an equivalent volume of body hair could be used. Head hair denotes only scalp hair, while body hair covers all other hair types (such as facial, axillary, etc.).
Process Overview
The drug test result in a laboratory is divided into four crucial steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary processing stage where a sample is incorporated into a laboratory’s system. It involves ensuring the sample is sealed and transported correctly, assigning a unique LAN (Laboratory Accessioning Number), and inputting any missing information not captured by an electronic chain of custody system.
Screening serves as an initial rapid examination for drug abuse. This cost-efficient step helps eliminate drug usage for most samples, yet any positive reads need confirmation for legal acceptance. Samples testing presumptive in Screening do require further verification.
If a sample appears positive during Screening, additional hair is extracted from the initial sample and set up for Extraction. This stage separates drugs from hair at significantly lower concentrations compared to other approaches (such as urine or oral fluid), making hair drug testing the most challenging technique to execute.
Positive screening results are verified through GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptive samples receive a wash before confirmation if necessary. The full process from Accessioning to Confirmation undergoes reviews under CAP (College of American Pathologists) Hair standards and conforms to ISO / IEC 17025 standards.

The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
Forensic Applications and Interpretation: One of the vital objectives of hair testing is its application in forensic investigations and legal proceedings. The SoHT meeting in Verona emphasized the significance of rigorous interpretation of analytical results and the need for standardized protocols. Manuscripts in this section present advancements in forensic toxicology, and have explored the challenges posed by emerging designer drugs and strategies to combat their proliferation.
