Accredited Drug Testing provides comprehensive hair follicle drug tests in San Jose, CA. If you need a hair drug or alcohol test, our specialty in hair testing is supported by centers across the country that conduct these tests. Typically, 1.5 to 2 inches of hair from your head or body is required. These tests can identify drugs, alcohol/ETG, and offer specific options tailored to your needs.
Recently, hair follicle drug testing has become a more common approach. Many employers, legal systems, and substance abuse experts now prefer it to traditional urine testing. Employers with strict drug policies, courts, and probation officers increasingly demand hair tests. The primary advantage is its extended detection span, up to 90 days, and collection under supervision, almost eliminating the chance of tampering. However, for drug use within the last 5 days, urine tests remain the most reliable.

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged record of substance use by encapsulating biomarkers within the fibers of its growing strands. When obtained close to the scalp, hair offers nearly a 90-day detection period for alcohol and various drugs. Hair collection is straightforward, relatively tamper-resistant, and simple to transport.
A sample measuring 1.5 inches consisting of about 200 hair strands (comparable to a #2 pencil) nearest the scalp yields 100mg, which is optimal for screening and confirmations. For tests like EtG or those exceeding 10 panels, 150mg is advised. Using a jeweler’s scale for measurement is recommended. If head hair is absent, a comparable amount of body hair may be gathered. When mentioning head hair, it pertains solely to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result is comprised of four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage where a sample is processed into the laboratory system, including verifying shipment integrity, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry beyond the electronic chain of custody system.
Screening involves a preliminary check for drug abuse. Although cost-effective for ruling out drug presence in most samples, a positive screening requires confirmation for court acceptability. Samples testing presumptively positive in Screening need additional confirmation.
For a Screening-flagged presumptive positive, more hair is extracted from the specimen for further Extraction. Drugs are retrieved from hair at lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening notably challenging.
GC/MS, GC/MS/MS, or LC/MS/MS confirm any positive screening results. Presumptive positive samples undergo washing before Confirmation as needed. The complete laboratory process, from Accessioning to Confirmation, adheres to CAP (College of American Pathologists) Hair designation and is accredited under ISO/IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: While commonly termed "hair follicle tests," the analysis targets the hair strand itself, not the follicle beneath the scalp.

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.
In conclusion, the special issue of Drug Testing and Analysis, featuring manuscripts from the SoHT–GTFI meeting in Verona 2022, reflects the remarkable advancements achieved in this field. The manuscripts provide valuable insights into novel analytical techniques, biomarkers, pharmacokinetics, forensic applications, and ethical considerations. As we embrace these advancements, we pave the way for a safer, healthier society, where drug testing and analysis serve as powerful tools in protecting public health and maintaining integrity in various sectors.
