Accredited Drug Testing offers comprehensive hair follicle drug testing services in Carmel Valley, California. If a hair drug or alcohol test is necessary, Accredited Drug Testing specializes in hair testing. We have facilities in all cities nationwide to conduct the required tests. Generally, 1.5 to 2 inches of head or body hair is needed. Hair tests can examine drugs, alcohol/ETG, or be customized for specific testing needs.
The popularity of hair follicle drug testing has recently grown. Many organizations, judicial systems, and substance abuse experts now opt for hair tests over traditional urine tests. Hair follicle drug tests are used by employers, judicial systems, and individuals on probation who adopt zero-tolerance drug policies. The chief advantage of hair follicle testing is the extended detection period, typically up to 90 days, with an observed collection process that is hard to bypass. Urine tests, however, remain more precise for drug use detection within the past 5 days.

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 analysis has evolved into a significant mechanism for identifying drug and alcohol consumption. Hair retains a prolonged record of alcohol and drug intake by encasing biomarkers within the strands of hair as they grow. When procured near the scalp, such hair provides around a three-month detection period for alcohol and drugs. It is straightforward to collect hair, challenging to tamper with, and easy to transport.
A segment of 1.5 inches consisting of roughly 200 hair strands (about #2 pencil diameter) nearest to the scalp results in a 100mg hair collection, the optimal quantity for testing and validation. For EtG, additional tests, and/or beyond 10-panel examinations, gathering 150mg is advisable. It's prudent to use a jeweler’s scale for measuring the hair sample. If head hair isn't an option, an equivalent amount of body hair can be taken. "Head hair" pertains solely to scalp hair, whereas "body hair" encompasses all other varieties (facial, axillary, etc.).
Process Overview
There are four principal steps in the laboratory procedure for generating a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample undergoes its initial procedural handling in a laboratory's framework. This involves ensuring correct sealing and shipping of the sample, designating a random LAN (Laboratory Accessioning Number), and finishing up any extra data input not already handled by an electronic custody tracking system.
Screening pertains to the initial rapid assessment for substance abuse presence. While it offers an economical approach to dismiss drug use across most samples, a positive screening necessitates confirmation for courtroom admissibility. Samples indicating presumptive positivity in Screening must undergo additional confirmation.
Should a sample indicate presumptive positivity in the Screening phase, more hair is extracted from the primary sample for Extraction preparation. In this stage, substances are drawn from the hair at lower concentrations than witnessed in other methods (e.g., urine or oral fluid), thus marking hair drug screening as a particularly challenging approach.
Confirmation for any positive screening is executed using GC/MS, GC/MS/MS or LC/MS/MS methodologies. All samples showing presumptive positivity are washed as required before confirmation. The entire laboratory sequence from Accessioning through to Confirmation is verified following both CAP (College of American Pathologists) Hair guidelines and in line with ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Commonly termed "hair follicle tests", these assessments are conducted on the hair strand itself, not the follicle situated 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.
