Accredited Drug Testing offers extensive hair follicle testing for drugs in Southeast Marin, California. Whether you require a hair drug or alcohol test, our expertise in hair testing spans nationwide, with facilities available in every city to conduct the testing. Typically, having 1.5 to 2 inches of hair on your scalp or body is necessary. A variety of tests can be designed to detect drugs, alcohol/ETG, and other specific testing needs.
Recently, hair follicle drug tests have become a preferred method for substance detection. Increasing numbers of employers, courts, and substance abuse experts are opting for hair tests over the traditional urine analysis. These tests are ideal for companies with zero-tolerance policies, legal settings, and probation scenarios. One main advantage of hair drug tests is their extended detection window—up to 90 days—and the supervised manner in which samples are collected, which make attempts to falsify results exceedingly difficult. Despite this, urine tests remain the best option for identifying short-term drug usage within the previous five days.

Hair analyses have gained recognition as an effective method for identifying drug and alcohol consumption. Hair encases a prolonged record of alcohol and drugs by capturing biomarkers in the strands of the hair as it grows. When collected near the scalp, hair offers an approximate 3-month detection timeframe for alcohol and other drugs. Hair is straightforward to gather, somewhat resistant to tampering, and convenient to transport.
An ideal 1.5-inch sample consisting of about 200 hair strands (approximately the width of a #2 pencil) nearest to the scalp provides 100mg, optimal for screening and confirmation. For EtG, add-ons, and/or panels exceeding 10, a 150mg specimen is advised. We suggest utilizing a jeweler’s scale for weighing the sample. If scalp hair isn't available, an equivalent quantity of body hair can be collected. When mentioning head hair, it specifically refers to scalp hair. Body hair includes other types (facial, axillary, etc.).
Process Overview
The testing process in a laboratory involves four essential steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial integration of a sample into the lab system. This step ensures the sample is sealed, shipped correctly, assigns a random Laboratory Accessioning Number (LAN), and completes any additional data entry not supplied by an electronic chain of custody system.
Screening provides a preliminary check for abuse substances. While a cost-effective means to eliminate drug use in most samples, a positive screen requires confirmation for court admissibility. Samples that are presumptively positive in Screening need a secondary verification.
A presumptive positive in Screening necessitates more hair being extracted from the original specimen for Extraction. Here, drugs are isolated from hair at much lower concentrations than other methods (such as urine or oral fluid), making hair drug screening a challenging method to conduct.
A positive screening result is confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo washing before confirmation as needed. The complete process from Accessioning to Confirmation is audited under the College of American Pathologists (CAP) Hair designation and ISO / IEC 17025 standards.

Limitations:
Note: Although commonly called "hair follicle tests", the analysis focuses on the hair strand, not the follicle beneath the scalp.

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.
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.
