Accredited Drug Testing offers comprehensive hair follicle drug testing services in Cedar Ridge, California. With centers nationwide, including all cities, we specialize in hair drug and alcohol testing. Generally, 1.5 to 2 inches of hair from the crown or body is sufficient for testing. Our hair tests can detect drugs, alcohol/ETG, and offer other custom options.
In recent times, hair follicle drug testing has become a prevalent method for detecting drug use. Employers, courts, and substance abuse professionals often prefer hair tests over standard urine tests. This method benefits those with zero-tolerance drug policies and individuals on probation. A significant advantage is the longer detection period of up to 90 days, under observed collection, making it hard to bypass. For recent drug use, however, urine tests remain most accurate.

Hair analysis has emerged as an effective means for identifying the use of drugs and alcohol. Hair records a prolonged history of substance use by capturing biomarkers within the strands as they grow. When sampled near the scalp, hair can reveal drug and alcohol presence for up to three months. Hair samples are easy to collect, hard to tamper with, and simple to transport.
A sample of hair 1.5 inches long, comprising 200 strands (about the thickness of a #2 pencil), taken from the scalp, provides 100mg of hair—ideal for testing. For EtG, additional tests, or tests exceeding 10 panels, 150mg is advisable. We suggest using a jeweler's scale to weigh the sample. In the absence of scalp hair, the same amount of body hair is suitable. "Head hair" specifically denotes scalp hair, while "body hair" includes all other types (such as facial or axillary hair).
Process Overview
The laboratory processing of drug test outcomes involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase of integrating a sample into the lab's system. This step confirms that the sample is adequately sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and completes any supplementary data entry not covered by an electronic chain of custody.
Screening offers a preliminary check for drug presence. While Screening serves as a cost-effective method to largely dismiss drug use in samples, positive screens require verification to be court-admissible. Samples with presumed positive results during Screening necessitate further confirmation.
Presumptively positive samples in Screening lead to additional hair extractions from the brought specimen for the Extraction phase. Here, drugs are isolated from hair at much lower concentrations than in other testing methods (such as urine or oral fluid), highlighting the complexity involved in hair drug screening.
Any positive screening outcomes are validated through GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positives are cleansed prior to confirmation as necessary. The whole lab process from Accessioning to Confirmation undergoes a review by the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: While commonly termed "hair follicle tests", these tests examine the hair shaft 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.
