Accredited Drug Testing offers comprehensive hair follicle drug testing services in Sparks, Nevada. If you require a hair-based drug or alcohol test, our specialty lies in hair testing, with centers across all cities Nationwide capable of conducting hair tests. Typically, 1.5 to 2 inches of hair from the crown or body is needed. These tests can detect drugs, alcohol/ETG, or other tailored options.
Recently, drug testing methods have increasingly incorporated hair follicle tests. Many employers, judicial systems, and Substance Abuse specialists now prefer hair drug tests over traditional urine tests. Organizations with zero-tolerance policies, court systems, and individuals on probation often use these tests. The main advantage is the extended detection window for drugs, up to 90 days, observed collection process, and difficulty in tampering. Yet, for the detection of recent drug use within the past 5 days, urine tests remain the most accurate.

The use of hair analysis has become recognized as an effective method for identifying the consumption of drugs and alcohol. Hair captures a long-term record of substance use by embedding biomarkers within the fibers as the hair grows. Collecting hair near the scalp can offer up to a three-month detection period for alcohol and other drugs. It's easy to collect, hard to tamper with, and straightforward to ship.
A 1.5-inch hair sample consisting of roughly 200 strands (comparable to the thickness of a #2 pencil) from the scalp yields 100mg of hair, which is optimal for both screening and verification. For EtG, additional tests, or panels exceeding ten, a 150mg sample is advisable. We suggest using a jeweler’s scale for weighing the specimen. If scalp hair is not available, an equivalent amount of body hair may be utilized. When discussing head hair, we exclusively mean scalp hair, whereas body hair includes all other types such as facial and axillary hair.
Process Overview
The laboratory processing of a drug test result comprises four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial integration of a sample into a lab's system. This process ensures the sample is properly sealed and couriered, allocates a random LAN (Laboratory Accessioning Number), and finalizes any additional data input not covered by an electronic chain of custody.
Screening provides an initial assessment for substances of abuse. Although Screening is an economical way to exclude drug use in most samples, a positive outcome needs confirmation to be court-admissible. Any samples deemed presumptively positive during Screening need further confirmation.
Should a sample indicate presumptive positivity in Screening, additional hair is selected from the initial collection for Extraction. In this step, drugs are separated from the hair at a notably lower concentration than other techniques (such as urine or saliva), underscoring why hair drug testing is the most complex method to execute.
Confirming a positive result from the screening involves testing via GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples identified as presumptive positives are washed beforehand for Confirmation. The complete lab process, from Accessioning to Confirmation, undergoes evaluation under both the CAP (College of American Pathologists) Hair designation and is accredited to the 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. The manuscripts provide valuable insights into novel analytical techniques, biomarkers, pharmacokinetics, forensic applications, and ethical considerations. As we embrace these advancements, we pave the way for a safer, healthier society, where drug testing and analysis serve as powerful tools in protecting public health and maintaining integrity in various sectors. The research presented in this special issue will undoubtedly shape the future of drug testing and analysis, fostering collaboration and inspiring further innovation in this crucial area of scientific inquiry.
