In Searles Valley, California, Accredited Drug Testing provides thorough hair follicle drug testing. Whether you require a hair drug or alcohol test, our specialty lies in hair testing, with testing sites available across cities nationwide for conducting hair tests. A hair length of 1.5 to 2 inches from either the scalp or body is typically adequate. Hair analyses can detect drugs, alcohol/ETG, or be customized for other hair testing needs.
Hair follicle drug tests have increasingly become a prevalent method for drug testing. Employers, courts, and substance abuse professionals often request hair tests over traditional urine tests. Employers with strict drug policies, judicial systems, and probation officers rely on them for their extensive detection window—up to 90 days, rendering them hard to evade. However, for recent drug use within the last 5 days, urine tests maintain the highest accuracy.

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 method for identifying drug and alcohol usage. Hair strands preserve a historical record of substance intake by embedding biomarkers in the hair's fibers as it grows. When collected near the scalp, hair samples can reveal a detection window of up to three months for alcohol and other substances. The collection process is straightforward, difficult to tamper with, and easy to transport.
A 1.5-inch section containing around 200 hair strands (roughly the thickness of a #2 pencil) adjacent to the scalp typically yields 100mg, ideal for testing and validation. For tests involving EtG, additional analyses, or more than 10 panels, a sample of 150mg is advisable. It's suggested to measure the sample using a jeweler’s scale. Should scalp hair be unavailable, an equivalent quantity of body hair can be used. References to head hair pertain exclusively to scalp hair, while body hair encompasses other types such as facial and axillary hair.
Process Overview
The laboratory processing stages of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary phase, involving the integration of a sample into the lab’s system. It consists of confirming that the sample remains sealed and properly dispatched, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional data entry that the electronic chain of custody system doesn't provide.
Screening serves as the initial trial to spot drugs of misuse. Although cost-efficient for dismissing drug presence in most samples, a positive screening necessitates further verification for legal admissibility. Samples testing as presumptive positives during Screening undergo secondary confirmation.
For samples indicated as presumptive positives during Screening, additional hair is extracted from the original sample for the Extraction phase. This stage entails extracting drugs from hair at a significantly lower concentration than other methods (e.g., urine or oral fluid), distinguishing hair drug screening as the toughest methodology to execute.
Verification of any positive screen results is achieved through GC/MS, GC/MS/MS, or LC/MS/MS techniques. Samples identified as presumptively positive are washed as necessary before confirmation. The complete lab process from Accessioning to Confirmation is assessed under CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Although often described as "hair follicle tests," the analysis is conducted on 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.
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.
