In San Joaquin, California, Accredited Drug Testing offers a comprehensive hair follicle drug testing service. For individuals needing hair drug or alcohol examinations, our expertise lies in hair testing, with testing facilities available across all cities nationwide. Typically, hair from the crown or body, measuring 1.5 to 2 inches, is collected. These tests can screen for drugs, alcohol/ETG, or other tailored options.
The last few years have seen a growing preference for hair follicle drug testing. Employers, courts, and substance abuse professionals are increasingly opting for this method over standard urine tests. Companies with zero-tolerance policies, judicial systems, and probationary programs favor hair testing for its extended detection span of up to 90 days, its supervised collection, and minimal risk of tampering. However, for detection of very recent substance use within five days, urine tests remain more 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.
The utilization of hair testing has emerged as an effective method for uncovering drug and alcohol consumption. Hair retains a prolonged record of substance use by capturing biomarkers within the strands as they develop. A sample collected near the scalp can provide a detection period extending up to roughly three months for alcohol and drugs. This type of specimen is easy to gather, challenging to alter, and straightforward to transport.
A 1.5-inch segment comprising around 200 strands (comparable to a #2 pencil) nearest to the scalp yields 100mg, which is the ideal quantity for both screening and confirmation assays. For EtG assessments, supplementary tests, or panels exceeding 10, a 150mg sample is advisable. It is recommended to weigh the sample using a jeweler’s scale. In absence of scalp hair, an equivalent amount of body hair can be collected. References to head hair pertain exclusively to scalp hair, whereas body hair includes all other types (such as facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial handling of a sample as it enters the laboratory’s system. This process includes ensuring proper sealing and shipment of the specimen, assigning a random LAN (Laboratory Accessioning Number), and completing any data entry that the electronic chain of custody system does not furnish.
Screening executes a swift preliminary evaluation for substance misuse. Although Screening provides a cost-efficient way to eliminate drug use in many samples, a positive outcome here needs verification for court admissibility. Samples with preliminary positive Screening outcomes must undergo subsequent confirmation.
Should Screening show presumptive positivity, additional hair from the original specimen is readied for Extraction. At this stage, substances are gleaned from the hair at significantly lower concentrations than seen in alternative methods (like urine or oral fluid), rendering hair screening particularly intricate.
Confirmation of any Screening positives is done using GC/MS, GC/MS/MS, or LC/MS/MS methods. Prior to confirmation, all presumptive positives are washed as necessary. The entire lab process, from Accessioning to Confirmation, is assessed under both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 standards.

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.
