Accredited Drug Testing offers comprehensive hair follicle drug assessments in Carmichael, California. Should you require testing for drugs or alcohol, our expertise lies in hair testing, and we have facilities in numerous cities across the nation ready to conduct hair tests. Generally, 1.5 to 2 inches of scalp or body hair is needed. Hair tests can check for drugs, alcohol/ETG, or can be tailored for specific needs.
Recently, the hair follicle drug test has increasingly become a preferred method. This choice is popular among employers, courts, and Substance Abuse professionals, who often opt for it over the traditional urine test. It's favored by those enforcing strict drug policies. The key advantage is its extended detection period, up to 90 days, with observed sample collection making manipulation nearly impossible. Yet, urine tests remain the best for detecting recent drug use, typically within the past five days.

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 testing is recognized as an effective method for identifying drug and alcohol consumption. Hair contains a prolonged record of substance use by capturing biomarkers within the hair strand as it grows. When taken near the scalp, hair can offer a detection span of roughly three months for alcohol and drugs. Collecting hair is straightforward, relatively resistant to tampering, and simple to transport.
A 1.5-inch portion with approximately 200 hair strands (similar in width to a #2 pencil) near the scalp yields 100mg of hair, the optimal quantity for both screening and confirmation tests. For EtG, additional screenings, and/or tests exceeding 10 panels, 150mg of the specimen is suggested. We advise measuring the specimen on a jeweler’s scale. If scalp hair is not an option, an equivalent body hair amount can be utilized. When mentioning head hair, we specifically mean scalp hair. Body hair denotes all other hair forms (facial, axillary, etc.).
Process Overview
The key steps in the laboratory evaluation of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial handling of a sample in a lab’s framework. This step involves ensuring the sample was sealed and dispatched correctly, assigning a unique LAN (Laboratory Accessioning Number), and completing any further data input absent from an electronic chain of custody system.
Screening consists of a swift initial check for drug presence. While Screening serves as a cost-efficient measure to rule out drug usage in most cases, a positive screen requires confirmation to be permissible in legal proceedings. Samples that indicate a provisional positive in Screening warrant a secondary confirmation.
In the event a sample registers a provisional positive during Screening, additional hair is extracted from the original sample for Extraction. During this phase, drugs are extracted from hair at notably lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening one of the most challenging methods to conduct.
Confirmation for any positive from screening occurs through GC/MS, GC/MS/MS or LC/MS/MS. All provisional positive samples undergo washing before confirmation if necessary. The entire laboratory sequence from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Commonly termed "hair follicle tests", the analysis 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.
