Accredited Drug Testing provides comprehensive hair follicle drug testing services in Turlock, California. Our expertise in hair drug and alcohol testing is supported by a network of testing centers across the nation, all equipped to conduct hair tests. Typically, 1.5 to 2 inches of hair from the head or body is required. Our hair tests can screen for drugs, alcohol/ETG, or be customized to suit specific testing needs.
In recent trends, the inclusion of hair follicle drug tests as a testing method has seen a notable rise. Employers, judiciary systems, and substance abuse counselors are often opting for hair drug tests over traditional urine tests due to their effectiveness. These tests are favored by zero-tolerance employers, courts, and those monitoring individuals on probation. The key advantage is the extended detection window, up to 90 days, secured through an observed collection process, making it very challenging to tamper with. Urine tests still reign in accuracy for recent drug use within a 5-day window.

Hair testing is now a recognized method for identifying drug and alcohol consumption. Hair provides a prolonged timeline of alcohol and drug use by embedding biomarkers in the strands of growing hair. Collected close to the scalp, it offers roughly a 3-month detection timeline for drugs and alcohol. Hair is easy to collect, difficult to tamper with, and simple to transport.
A 1.5-inch hair sample of approximately 200 strands (about the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal sample size for screening and confirmation. For EtG, additional tests, or those exceeding 10 panels, 150mg of the sample is advised. We suggest using a jeweler’s scale for precise measurement. If scalp hair is unavailable, an equal portion of body hair can be collected. When we mention head hair, it pertains solely to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The four principal steps in the lab processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the primary processing of a sample into a laboratory's framework. This step ensures the sample was appropriately sealed and dispatched, assigns a unique LAN (Laboratory Accessioning Number), and completes any pending data entry absent in an electronic chain of custody framework.
Screening is an expedited initial examination for drugs of abuse. Although Screening efficiently rules out drug use in the bulk of samples, a positive result must be validated for courtroom acceptability. Samples presumed positive in Screening demand secondary confirmation.
If Screening reveals a presumptive positive, more hair is extracted from the initial specimen for the Extraction phase. During this stage, drugs are extracted from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), making hair drug screening the most complex to execute.
Confirmation of any positive screening result is done with GC/MS, GC/MS/MS, or LC/MS/MS technologies. All presumptive positive samples receive a wash before confirmation as required. The full lab process, from Accessioning to Confirmation, undergoes review under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.

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.
