In Mendota, California, Accredited Drug Testing provides thorough hair follicle drug testing. As specialists in hair testing, we have testing facilities nationwide equipped to conduct such tests. Generally, 1.5 to 2 inches of hair are required from the crown or body. This type of testing can detect drugs, alcohol/ETG, or other specific substances.
There has been an increased use of hair follicle drug tests in recent years. Many companies, courts, and substance abuse professionals now prefer this method over conventional urine tests. Employers with strict no-drug policies, courts, and probation officers often choose hair testing for its extended detection timeline, typically up to 90 days. This method is reliable and difficult to manipulate, but for recent drug use within 5 days, urine tests are more accurate.

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 means for uncovering the use of drugs and alcohol. Hair captures biomarkers within the strands of the growing hair, offering a detailed timeline of substance use. When taken near the scalp, it can present an approximately 3-month detection period for drugs and alcohol. Collecting hair is straightforward, hard to tamper with, and convenient for mailing.
A sample measuring 1.5 inches with roughly 200 hair strands (similar to the thickness of a #2 pencil) closest to the scalp yields 100mg of hair, which is the preferred quantity for analysis and confirmation. For EtG, additional requests, and/or tests surpassing 10 panels, a 150mg sample is advised. Measurement should be performed using a jeweler’s scale. When scalp hair is unavailable, gather comparable body hair. Note that head hair means only scalp hair. Body hair denotes all other types (like facial, axillary, etc.).
Process Overview
The principal stages in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial stage of a sample entering the lab system. This consists of ensuring proper sealing and shipping of the sample, assigning it a random LAN (Laboratory Accessioning Number), and executing any further data input absent from an electronic chain of custody system.
Screening denotes an initial brief examination for drugs of abuse. Screening is a cost-efficient method to dismiss drug usage for most samples, but positive results require confirmation for court admissibility. Any samples presumptively positive in Screening must undergo a secondary confirmation.
When a sample tests presumptively positive in the Screening phase, more hair is extracted from the original sample and set for Extraction. In this phase, drugs are removed from hair at much lower concentrations than through other methods (e.g., urine or oral fluid), distinguishing hair drug testing as the most challenging method to execute.
Confirmation of any positive Screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed before confirmation as required. The complete lab procedure from Accessioning to Confirmation is verified under the CAP (College of American Pathologists) Hair designation and accredited to ISO / IEC 17025 standards.

Limitations:
Note: Though frequently termed as "hair follicle tests", the test targets the hair strand rather than the hair 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.
