Accredited Drug Testing offers full hair follicle drug testing services in Perez, California. If you're in need of a hair-based drug or alcohol test, our specialty lies in hair analysis, and with testing facilities across all U.S. cities, we're well-equipped for your needs. Generally, 1.5 to 2 inches of hair from the scalp or body is optimal. Our hair tests can assess drugs, alcohol/ETG, and other tailored testing options.
Recently, the use of hair follicle drug testing has become more common in drug screening methods. Employers, judicial systems, and Substance Abuse counselors often prefer hair tests over traditional urine screens. This method is favored by employers with strict anti-drug policies, courts, and probation programs. Hair follicle tests boast an extended detection window of up to 90 days, require observed collections, and are nearly immune to tampering. Nonetheless, for detecting recent drug use within five days, urine tests remain the preferred method.

Hair testing has emerged as a robust resource for identifying drug and alcohol usage. Hair retains a lengthy record of alcohol and other substances by embedding biomarkers within the strands as they grow. When gathered near the scalp, hair can reveal usage within an estimated 3-month span for alcohol and other drugs. Hair sampling is straightforward, resistant to tampering, and convenient for transport.
A sample measuring 1.5 inches, comprising around 200 hair strands (similar in size to a #2 pencil) near the scalp, supplies 100mg of hair, an optimal quantity for both screening and verification purposes. For EtG enhancements, or evaluations exceeding 10 panels, 150mg of the sample is advised. We suggest measuring the sample on a jeweler’s scale. If scalp hair is not available, a comparable quantity of body hair is an alternative. Regarding head hair, we specifically refer to scalp hair. Body hair encompasses all other varieties (facial, axillary, etc.).
Process Overview
The primary stages in the laboratory handling of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary processing of a sample within a lab’s system. This step involves confirming the sample's proper sealing and shipping, generating a random LAN (Laboratory Accessioning Number), and completing any extra data entry absent in an electronic chain of custody system.
Screening involves an introductory rapid assessment for drug misuse. Although Screening presents a cost-efficient method to eliminate drug usage in the majority of samples, a positive screen must undergo confirmation to hold up in court. Samples that appear presumptively positive during Screening require an additional confirmation.
If a sample is deemed presumptively positive during the Screening phase, further hair is extracted from the initial sample for the Extraction stage. In this phase, substances are isolated from hair at a much reduced concentration compared to other methods (e.g., urine or oral fluid), contributing to hair drug screening being the most elaborate method to execute.
Confirmation of any positive screening is conducted using GC/MS, GC/MS/MS, or LC/MS/MS methodologies. All samples showing presumptive positives are cleaned before confirmation as necessary. The complete lab process from Accessioning to Confirmation undergoes inspection under both the CAP (College of American Pathologists) Hair designation and the ISO/IEC 17025 standard accreditation.
Advantages of hair drug testing:
Limitations:
Note: Although occasionally termed "hair follicle tests", the test actually examines the hair strand, not 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.
