Accredited Drug Testing offers comprehensive hair follicle drug testing in Colma, California. Whether it's for drug or alcohol detection, we pioneer in hair testing services with centers across major U.S. cities, including nationwide locations. Typically requiring 1.5 to 2 inches of hair from your scalp or body, our tests can evaluate for drugs, alcohol/ETG, or be tailored for other specific assessments.
More recently, hair follicle tests have gained traction in drug screening approaches. Employers, judicial systems, and Substance Abuse specialists are setting hair tests as a standard, replacing traditional urine tests. Hair follicle tests are favored due to their extended detection duration - up to 90 days - the facilitated observation during collection, and their resistance to tampering. Nevertheless, urine tests remain prevalent for identifying drug use within a brief 5-day window.

Hair testing is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair offers a longer-term record of drugs and alcohol by capturing biomarkers within the fibers of the developing hair strand. When gathered near the scalp, hair can reveal up to about three months of detection for substances. Hair is straightforward to collect, relatively resistant to tampering, and simple to transport.
A 1.5-inch portion of roughly 200 hair strands (about the width of a #2 pencil) nearest to the scalp will yield 100mg of hair, the optimal sample for analysis. For EtG, additional tests, and/or those exceeding 10 panels, 150mg of the sample is advised. It is suggested to weigh the sample using a jeweler's scale. If scalp hair is unavailable, a similar quantity of body hair may be used. When mentioning head hair, we refer exclusively to scalp hair. Body hair includes all other hair types (facial, axillary, etc.).
Process Overview
The drug testing laboratory process involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first step where a sample is processed into the lab’s system. This step confirms the sample was securely sealed and properly shipped, assigns it a random LAN (Laboratory Accessioning Number), and completes any extra data entry not supplied by digital chain of custody systems.
Screening is an initial quick assessment for substance abuse. Although Screening is an economical approach to rule out drug consumption in most samples, a positive outcome needs to be confirmed for courtroom legitimacy. Samples that test presumptive positive in Screening demand a secondary confirmation.
If a specimen tests presumptive positive during Screening, more hair is extracted from the original sample for Extraction. At this stage, drugs are extracted from hair at significantly lower concentrations than in other methods (e.g., urine or oral fluid), marking hair drug analysis as the most challenging to execute.
Confirmation of a positive screening result is done using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples undergo washing before confirmation as necessary. The entire lab process, from Accessioning to Confirmation, is scrutinized under CAP (College of American Pathologists) Hair criteria and complies with ISO/IEC 17025 standards.

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. The research presented in this special issue will undoubtedly shape the future of drug testing and analysis, fostering collaboration and inspiring further innovation in this crucial area of scientific inquiry.
