For those in need of hair drug or alcohol tests, Accredited Drug Testing specializes in these assessments, and operates testing centers in cities nationwide equipped to conduct hair testing. Typically, 1.5 or 2 inches of hair from the crown or body can be used for evaluation, with tests available for drugs, alcohol/ETG, or other specialized analysis.
Recently, drug testing methods increasingly include hair follicle exams. Employers, courts, and substance abuse experts often require hair drug tests instead of urine tests. Hair follicle testing is favored by employers with strict drug policies, courts, and those on probation, due to its extended detection period of up to 90 days and collection process, making it difficult to tamper. However, urine tests remain most precise for recent drug usage within five 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 testing is increasingly viewed as an effective means for identifying drug and alcohol consumption. Hair captures a lengthy record of substance use by embedding biomarkers within the structure of the hair as it grows. Obtained near the scalp, hair samples can offer up to roughly a 3-month period for detecting alcohol and drugs. Hair collection is straightforward, somewhat challenging to tamper with, and simple to transport.
A 1.5-inch segment containing around 200 hair strands (about a #2 pencil width) near the scalp provides 100mg of hair, which is the ideal sample size for both screening and confirmation. For EtG, additional analyses, and/or panel tests exceeding 10, 150mg of specimen is ideal. We suggest utilizing a jeweler’s scale for weighing the sample. If scalp hair is unavailable, a comparable quantity of body hair can be used. Head hair specifically refers to scalp hair, whereas body hair encompasses facial, axillary, and other hair types.
Process Overview
The main stages in laboratory drug test processing include Accessioning, Screening, Extraction, and Confirmation.
Accessioning begins with integrating a sample into a lab system. This entails confirming that the sample was properly sealed and shipped, assigning a LAN (Laboratory Accessioning Number) randomly, and completing any further data entry not captured by an electronic chain of custody.
Screening is a preliminary, rapid test for drugs. Although it is an economical method to rule out usage in most samples, positive screenings must be verified for legal admissibility. Samples with preliminary positive results require additional confirmation.
If a screening returns possibly positive, more hair is extracted from the initial specimen and prepared for Extraction. The Extraction phase isolates drugs from hair at lower concentrations than other methods (e.g., urine or oral fluid), making hair drug testing particularly complex.
Confirming any positive screen involves techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptively positive samples are cleaned as needed. From Accessioning to Confirmation, every lab process is scrutinized under the CAP (College of American Pathologists) Hair accreditation 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. The manuscripts provide valuable insights into novel analytical techniques, biomarkers, pharmacokinetics, forensic applications, and ethical considerations.
