Accredited Drug Testing offers thorough hair follicle drug testing services in Claremont, California. If a hair drug or alcohol test is required, Accredited Drug Testing excels in hair testing, with centers available in all cities across the nation capable of conducting these tests. Generally, 1.5 to 2 inches of hair on the head or body can be used. Hair tests enable analysis for drugs, alcohol/ETG, or other tailored testing needs.
Over recent years, hair follicle drug tests have become a more common method of drug testing. Various entities such as employers, courts, and Substance Abuse specialists now prefer hair drug tests over urine tests. Hair follicle testing is a choice for zero-tolerance employers, courts, and those on probation. The main advantage is its extended drug use detection window, up to 90 days, with an observed collection process, making it nearly unfeasible to manipulate. Nevertheless, for detecting drug use within the past 5 days, urine tests remain the most precise.

Hair testing is recognized as an effective method for identifying drug and alcohol use. It offers a long-term history of alcohol and drug consumption by embedding biomarkers within the hair fibers as they grow. Collected near the scalp, hair samples can exhibit a detection window of up to 3 months for alcohol and drugs. Hair is easy to gather, relatively difficult to tamper with, and convenient for mailing.
Collecting a 1.5-inch sample, approximately 200 strands of hair (comparable to the size of a #2 pencil) nearest to the scalp, will yield 100mg of hair, which is the optimal sample size for both screening and confirmation. For EtG, additional analysis, and/or tests exceeding 10 panels, 150mg of the sample is suggested. It’s advisable to weigh the sample using a jeweler’s scale. If scalp hair is unavailable, a comparable quantity of body hair can be collected. References to head hair pertain exclusively to scalp hair. Body hair denotes all other types of hair (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result is composed of four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial integration of a sample into a laboratory’s system, ensuring the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry absent from an electronic chain of custody system.
Screening conducts an initial rapid assessment for drugs of abuse. While it is a cost-effective strategy to eliminate drug use in most samples, a positive screen requires confirmation to be legally valid. Samples presumptively positive in Screening necessitate further confirmation.
Should a sample show a presumptively positive result in the Screening phase, more hair is extracted from the initial sample to prepare for Extraction. In this phase, drugs are extracted from hair at much lower concentrations than other methodologies (e.g., urine or oral fluid), making hair drug screening a challenging methodology to execute.
Confirmation of any positive screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples testing presumptive positive are washed prior to confirmation as necessary. The comprehensive laboratory process, spanning Accessioning to Confirmation, is assessed under both the CAP (College of American Pathologists) Hair categorization and the ISO / IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: Commonly termed as "hair follicle tests”, the test actually examines the hair strand rather than 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. 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.
