Accredited Drug Testing offers comprehensive hair follicle drug testing services in Winona, Mississippi. For those in need of a hair drug or alcohol assessment, Accredited Drug Testing focuses on hair examinations, with testing facilities available in cities nationwide ready to conduct these tests. Typically, 1.5 to 2 inches of hair from the crown or body can be used. Hair testing can detect drugs, alcohol/ETG, or other tailored testing needs.
Lately, drug testing methods have increasingly turned to hair follicle examinations. Various employers, judicial systems, and substance abuse professionals now require hair-based drug evaluations instead of conventional urine assessments. Hair follicle tests are favored by employers with zero-tolerance policies, courts, and probation services. The main advantage of hair testing is its extended 90-day detection window, drawn under observation and nearly tamper-proof. However, for detecting drug use within the last five days, urine testing remains the most precise method.

Hair analysis has emerged as an effective technique for identifying drug and alcohol consumption. Hair captures a long-term record of substance use by embedding biomarkers within the strands of hair as it grows. When taken near the scalp, hair can offer a roughly 3-month time frame for detecting drugs and alcohol. Hair collection is straightforward, challenging to tamper with, and convenient to transport.
A sample measuring 1.5 inches, consisting of approximately 200 hair strands (comparable to the thickness of a #2 pencil) near the scalp, yields 100mg of hair, which is the ideal quantity for both screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, a specimen of 150mg is advisable. It is suggested to use a jeweler’s scale for weighing the sample. If scalp hair is not obtainable, a similar quantity of body hair can be used. Head hair refers exclusively to scalp hair, while body hair denotes all other types (such as facial, axillary, etc.).
Process Overview
The laboratory procedure for processing a drug test result encompasses four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a sample into a laboratory's framework. This process includes ensuring the sample was properly sealed and sent, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional data entry absent in an electronic chain of custody system.
Screening conducts an initial swift check for substances of abuse. Although Screening is a cost-efficient method to eliminate drug usage in most samples, a positive screen necessitates a confirmation to be court-admissible. Presumptively positive Screening samples require subsequent confirmation.
In cases where Screening indicates a presumptive positive, further hair is extracted from the original sample and prepared for Extraction. In this process, substances are extracted from hair at considerably lower levels than in other approaches (e.g., urine or oral fluid), explaining why hair drug analysis is the most challenging method to implement.
Confirmation of any positive screening finding is performed utilizing GC/MS, GC/MS/MS, or LC/MS/MS. All samples that test presumptively positive undergo washing prior to confirmation as necessary. The full laboratory sequence from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair classification and accredited to ISO / IEC 17025 guidelines.
Advantages of hair drug testing:
Limitations:
Note: Although commonly referred to as "hair follicle tests," the actual test examines the hair strand rather than 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. 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.
