Accredited Drug Testing provides comprehensive hair follicle drug testing services in Greenview, California. For those in need of either a hair drug or alcohol test, Accredited Drug Testing is a specialist in this area, boasting testing centers in numerous cities across the nation capable of conducting hair tests. Typically, 1.5 to 2 inches of hair on the head's crown or from the body is required. Hair tests are suitable for drugs, alcohol/ETG, or other specific options.
Recently, hair follicle drug tests have become a more common method in drug testing ventures. A growing number of employers, judicial systems, and Substance Abuse experts now prefer hair drug tests over traditional urine tests. This type of testing is particularly valued by employers with zero-tolerance policies, courts, and for individuals on probation. It offers a main advantage of detecting drug use over an extended period, usually up to 90 days, involves a monitored collection process, and is challenging to manipulate. However, a urine test remains the most reliable when detecting drug use within a 5-day period.

Hair analysis is now considered an effective method for identifying the use of drugs and alcohol. Using hair allows for a prolonged history of alcohol and drug use by capturing biomarkers within the fibers of the newly forming hair strand. When samples are taken near the scalp, they can offer roughly a 3-month detection timeframe for drugs and alcohol. Collecting hair is straightforward, challenging to tamper with, and simple to transport.
An optimal sample of 1.5 inches consisting of about 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp produces 100mg of hair, which is ideal for both screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, 150mg of the specimen is advised. It's suggested to weigh the sample using a jeweler's scale. If scalp hair is not available, an equivalent amount of body hair can be used. The term head hair specifically refers to scalp hair. In contrast, body hair encompasses all other types (such as facial or axillary hair).
Process Overview
The laboratory processing of a hair drug test includes four main phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the sample's initial incorporation into the laboratory's system. Steps entail confirming the proper sealing and shipment of the sample, assigning it a unique LAN (Laboratory Accessioning Number), and completing any necessary data input absent from an electronic chain of custody system.
The Screening phase entails a preliminary rapid assessment for potential drug use. Although Screening offers a cost-efficient means to dismiss drug use for most samples, any positive results from Screening must undergo confirmation to be valid in court. Samples that screen as presumably positive require additional confirmation.
Should a sample screen as presumably positive in the initial phase, additional hair is extracted from the original sample and readied for the Extraction phase. Here, drug components are isolated from the hair at concentrations much lower than those found in other methods (such as urine or saliva), which contributes to hair drug testing being the most intricate methodology.
Confirmation for any positive screen results is done through methods like GC/MS, GC/MS/MS, or LC/MS/MS. All supposed positive samples get washed before confirmation as necessary. The entire lab process, from Accessioning through to Confirmation, gets reviewed under both the CAP (College of American Pathologists) Hair designation and adherence to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although often named "hair follicle tests", the testing is conducted on the hair strand itself and 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.
