Accredited Drug Testing provides comprehensive hair follicle drug evaluations in Harriston, Mississippi. Whether for drugs or alcohol, our expertise lies in hair analysis, with test centers spread Nationwide offering hair testing services. Typically, 1.5 to 2 inches of crown or body hair is needed. Hair samples can determine the presence of drugs, alcohol/ETG, or other tailored testing options.
Recently, there's been a trend toward using hair follicle drug tests for drug screening. Many businesses, judicial systems, and substance abuse professionals now prefer hair drug tests over conventional urine tests. These tests are ideal for employers with strict anti-drug policies and for those under legal scrutiny. The main advantage is a 90-day detection window, coupled with observed sample collection, making it nearly foolproof. Yet, for recent drug activity within 5 days, urine tests remain the most precise.

Hair analysis stands out as a valuable method for identifying substance usage. The hair captures biomarkers within its growing strand fibers, creating a comprehensive history of alcohol and drug presence. When taken near the scalp, hair can offer up to a 3-month insight into the usage of alcohol and drugs. Collection is straightforward, tampering is challenging, and shipping is uncomplicated.
To obtain the ideal screening sample, gather a 1.5-inch segment of roughly 200 hair strands (comparable to the size of a #2 pencil) nearest to the scalp, totaling 100mg of hair. For tests involving EtG, additional tests, or more than 10 panels, 150mg is advised. We suggest using a jeweler’s scale to measure the specimen. If scalp hair is not an option, an equivalent amount of body hair can be collected. By "head hair," we mean scalp hair only, while "body hair" encompasses all other types (facial, axillary, etc.).
Process Overview
The process of evaluating a drug test in the lab involves Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is first introduced into the lab’s system—making sure it was properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and performing any additional data input absent from an electronic chain of custody.
Screening offers an initial, efficient assessment for drugs of abuse. It is cost-effective for excluding drug use in most samples, but a positive result requires confirmation for legal admission. Samples presumed positive in Screening necessitate further confirmation.
Should a sample test positive in Screening, additional hair is taken from the initial batch for Extraction. This step involves extracting drugs from hair at much lower concentrations than other methods (e.g., urine or oral fluid), emphasizing why hair drug analysis is complex.
Positive results in Screening undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are washed as necessary before confirmation. The complete lab process, from Accessioning to Confirmation, complies with both the CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Often called "hair follicle tests," the actual test examines the hair strand, not 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.
