Accredited Drug Testing offers thorough hair follicle drug screening in Garden Grove, CA. For those needing a hair drug or alcohol test, we are experts in hair testing with facilities available nationwide, including all major cities, for performing hair tests. Typically, 1.5 to 2 inches of head or body hair is required for most conditions. Hair tests can identify drugs, alcohol/ETG, or offer other specialized hair testing options.
In recent years, hair follicle testing has become a more common method for drug testing. Many employers, judicial systems, and addiction specialists favor a hair drug test over a conventional urine test. Organizations with zero-tolerance drug policies, courts, and probation cases primarily rely on hair follicle drug tests. A major advantage of hair testing is the extended detection period, which can last up to 90 days, collected under supervision and nearly foolproof. However, for identifying drug use within the past 5 days, urine tests remain the most precise.

When you're searching for hair drug testing near me or hair drug testing locations, we provide a simple and convenient process to find a drug and alcohol testing location near you that is certified to provide all of your drug and alcohol testing needs.
Hair analysis is now recognized as an effective method for identifying drug and alcohol usage. Hair can record a long-term record of substances by embedding biomarkers within the hair's fibers as it grows. When gathered close to the scalp, hair provides a detection period of up to around 3 months for alcohol and other substances. Hair collection is straightforward, relatively tamper-resistant, and convenient for transport.
Collecting a 1.5-inch segment of roughly 200 hair strands (about the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal sample for testing and confirmation. For EtG, additional tests, and/or panels over 10, 150mg of hair is preferable. Using a jeweler’s scale to weigh the sample is recommended. If scalp hair can't be collected, an equivalent quantity of body hair may be used. "Head hair" specifically refers to scalp hair, while "body hair" encompasses all other types (facial, underarm, etc.).
Process Overview
The four primary phases in processing a drug test in a lab include Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial integration of a sample into a lab's system, ensuring that it was properly sealed and transported, assigning it a LAN (Laboratory Accessioning Number) randomly, and completing additional data entry that the electronic chain of custody system doesn’t cover.
Screening is a preliminary swift check for substance abuse. Though cost-effective, Screening requires court-admissible confirmation for positive results. Samples with presumptive positive results during Screening need a confirmation follow-up.
Upon a presumptive positive result in Screening, more hair is extracted from the initial sample for further preparation in the Extraction stage. Here, drugs are isolated from hair at much lower concentrations compared to other methods (e.g., urine or saliva), making hair drug testing the most challenging method to execute.
Confirmation of any positive screening is done with GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples that are presumptively positive undergo washing before confirmation as necessary. We examine the comprehensive lab process from Accessioning to Confirmation according to both the CAP (College of American Pathologists) Hair standards and ISO/IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: Commonly termed as "hair follicle tests", this procedure analyzes the hair strand, excluding the under-scalp follicle.

The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.
It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.
Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.
Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis. 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. The pitfalls encountered when the exogenous/endogenous nature of a substance is questioned were presented and discussed. The special issue presents also manuscripts that delve into the ethical implications of drug testing in drug facilitated sexual assaults.
Clinical Applications of hair testing are witnessed by the insight on environmental tobacco smoke exposure, assessed by hair analysis in a population of students and the study of in utero-exposure to drugs of abuse through neonatal hair analysis. Exposure to drugs was also important in cases of child abuse/neglect, when the clinical purpose of hair testing merge with its forensic applications.
The legal framework surrounding hair testing and the achievement of guidelines to ensure fairness, accuracy, and confidentiality in drug testing practices have also been discussed,and the SoHT consensus on general hair testing and testing for drugs of abuse was presented at the meeting and published as a Letter to the Editor.
