Accredited Drug Testing provides comprehensive hair follicle drug testing services in Calpine, California. For those in need of a drug or alcohol hair test, Accredited Drug Testing is a specialist in this area, with testing centers nationwide. Typically, 1.5 to 2 inches of head or body hair is required for testing. Hair tests can detect drugs, alcohol/ETG, and other tailored options.
In recent times, drug testing methods have increasingly incorporated hair follicle tests. Many employers, courts, and substance abuse experts are opting for hair testing over traditional urine tests. Employers with zero-tolerance policies, courts, and probationers often favor hair testing due to its extended detection window, typically up to 90 days, with observation during collection, making it hard to falsify. However, for recent drug use within 5 days, urine tests remain the most precise.

When you're searching for hair drug testing near me or hair drug testing locations, we provide a simple and convenient process to find a drug and alcohol testing location near you that is certified to provide all of your drug and alcohol testing needs.
Hair testing is recognized as an effective instrument for detecting drug and alcohol consumption. Hair captures a prolonged history of alcohol and drug use by embedding biomarkers within the fibers of the developing hair strand. When taken near the scalp, hair can offer a detection window for alcohol and drugs for up to around three months. It is straightforward to collect, somewhat resistant to adulteration, and convenient to ship.
A 1.5-inch segment containing roughly 200 hair strands (comparable to a #2 pencil's thickness) closest to the scalp yields 100mg of hair, the ideal quantity for screening and verification. For EtG, add-ons, or tests above 10 panels, a 150mg sample is suggested. We advise using a jeweler’s scale to measure the specimen. If scalp hair isn't available, an equivalent amount of body hair can be used. When mentioning head hair, we mean scalp hair only. Body hair refers to all other types (facial, axillary, etc.).
Process Overview
The core steps in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves initially processing a sample into a lab's system. This step confirms that the sample was properly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data entry omitted by an electronic chain of custody system.
Screening provides an initial quick examination for drugs of abuse. While Screening is cost-efficient for excluding drug use in most samples, a positive screening outcome demands confirmation to be valid in court. Samples that test presumptively positive in Screening need a secondary confirmation.
If a sample tests presumptively positive during Screening, additional hair is extracted from the original specimen and readied for Extraction. Here, drugs are extracted from hair at a significantly lower concentration compared to other methods (e.g., urine or oral fluid), which makes hair drug screening the most challenging methodology to execute.
Confirmation of any positive screening result is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleaned before confirmation if necessary. The entire lab process, from Accessioning to Confirmation, undergoes review under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Note: Though commonly known as "hair follicle tests", the test itself examines the hair strand 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.
