Accredited Drug Testing offers extensive hair follicle drug testing services in Greenville, Kentucky. If you require hair drug or alcohol testing, our expertise lies in these areas, with facilities across the nation capable of conducting such tests. Generally, 1.5 to 2 inches of hair from the crown of your head or body can be used. We can analyze for drugs, alcohol/ETG, or provide other tailored hair testing solutions.
Recently, hair follicle drug testing has become increasingly common in drug screening. Many employers, courts, and Substance Abuse experts prefer this method over standard urine tests. Employers with zero-tolerance policies, as well as courts and probation officers, often utilize hair drug tests. A notable advantage is its ability to detect drug use over a longer span of up to 90 days, conducted in a monitored environment, making it hard to alter the results. However, urine tests remain the most precise for detecting recent drug use within the past five days.

Hair analysis is recognized as an effective means for identifying drug and alcohol consumption. The long-term record provided by hair is due to the entrapment of biomarkers within the fibers of the developing hair strand. Hair collected near the scalp can reveal a drug and alcohol use pattern for up to approximately three months. Collecting hair is straightforward, somewhat tamper-resistant, and easy to transport.
A sample comprising 1.5 inches of roughly 200 hair strands (equivalent to the size of a #2 pencil) nearest to the scalp will yield 100mg, which is the preferred quantity for both screening and confirmation. For EtG, additional tests, or tests exceeding 10 panels, a sample size of 150mg is advised. Utilizing a jeweler’s scale to weigh the specimen is suggested. Should scalp hair be absent, a corresponding quantity of body hair can be gathered. When we mention head hair, we mean only the scalp hair. Body hair encompasses all other types like facial and axillary hair.
Process Overview
The laboratory processing of drug test results typically involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is concerned with the initial handling of a sample when it enters a laboratory's system. It involves confirming that the sample is properly sealed and shipped, generating a random LAN (Laboratory Accessioning Number), and completing any further data entry that isn't provided by an electronic chain of custody system.
Screening is a preliminary drug check procedure. While Screening is an economical way to eliminate drug usage for the majority of samples, a positive result from the Screening must be verified for judicial acceptability. Samples that test positive during Screening need a secondary confirmation.
If a sample is deemed presumptively positive during Screening, additional hair is extracted from the original specimen for the Extraction phase. In this phase, the drugs are isolated from hair at much lower levels than other methods like urine or oral fluid, which makes hair drug screening the most challenging technique to execute.
GC/MS, GC/MS/MS or LC/MS/MS techniques are employed for the Confirmation of any positive Screening results. All samples indicated as presumptive positive undergo washing before the Confirmation step as necessary. The entire lab sequence from Accessioning to Confirmation is inspected under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.
Advantages of hair drug testing:
Limitations:
Note: Although commonly called "hair follicle tests", the actual analysis examines the hair strand rather than the hair follicle located beneath the scalp.

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.
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.

I needed a quick drug test for visitation with my children. I called at 6am they answered and set me up with a place a couple miles from my house to go get the test done, that was on Wednesday, I had the results on Friday afternoon and was able to see my kids on Saturday. Thank you for the help!
