Accredited Drug Testing offers comprehensive hair follicle testing services in Red Bluff, California. If you're in need of a hair-based drug or alcohol evaluation, Accredited Drug Testing specializes in such tests, with facilities across the entire nation capable of conducting them. Typically, 1.5 to 2 inches of hair is required for testing, sourced from either the crown or body. Hair analysis can identify drugs, alcohol/ETG, or other custom testing needs.
In recent years, the hair follicle drug test has become a more prevalent method for drug testing. Many companies, legal institutions, and substance abuse experts are opting for hair testing over standard urine testing. Employers, courts, and probation officers use hair follicle testing due to its longer detection window, typically up to 90 days, with rigorous observation minimizing tampering. However, for detecting drug use within the past 5 days, urine testing remains the most accurate method.

Hair analysis has emerged as a potent method for identifying drug and alcohol consumption. Hair captures a long-term record of substance use by embedding biomarkers within its growing strands. When taken near the scalp, hair can offer a detection period of up to three months for alcohol and drug use. Hair collection is straightforward, relatively tamper-proof, and easy to transport.
A 1.5-inch segment of around 200 hair strands (roughly the dimensions of a #2 pencil) closest to the scalp yields 100mg, which is the preferred amount for both screening and validation. For EtG testing, additional checks, and examinations exceeding ten panels, 150mg of the hair sample is advisable. It's suggested that the sample be weighed using a jeweler’s scale. If scalp hair cannot be obtained, an equivalent amount of body hair may be utilized. When discussing head hair, we mean specifically scalp hair, whereas body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
Laboratory processing of drug test results involves four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the preliminary handling of a sample upon entering a laboratory's system. This step confirms that the sample has been sealed and sent correctly, allocates a random LAN (Laboratory Accessioning Number), and completes any further data input not supplied by an electronic chain of custody protocol.
Screening is a primary rapid assessment for the presence of substances. While Screening offers a budget-friendly approach to exclude drug use in most samples, any positive finding must be verified to be court-admissible. Samples that test presumptively positive during Screening require subsequent confirmation.
In cases where a sample tests presumptively positive during the Screening phase, additional hair is extracted from the original sample for the Extraction phase. Here, substances are extracted from hair at much reduced concentrations compared to other techniques (e.g., urine or oral fluid), highlighting why hair drug analysis is the most challenging method to execute.
Confirmation of any positive results from Screening is carried out using GC/MS, GC/MS/MS, or LC/MS/MS methodologies. Presumptive positive specimens are cleaned pre-confirmation as necessary. From Accessioning through to Confirmation, the entire lab process is scrutinized under the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Commonly dubbed "hair follicle tests," the actual examination assesses the hair strand and not the sub-scalp follicle.

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.
