Offering comprehensive hair follicle drug tests in Princeton, Kentucky, Accredited Drug Testing excels in specialized hair and alcohol testing services. We have centers nationwide ready to conduct hair tests, which require 1.5 to 2 inches of hair, either from the head or body. Hair tests can screen for drugs, alcohol/ETG, as well as provide tailored testing options.
Recent trends in drug testing have increasingly turned towards hair follicle tests, favored by employers, courts, and Substance Abuse professionals over traditional urine tests. Employers upholding zero-tolerance policies, courts, and probation officers often prefer this method due to its longer detection window of up to 90 days and the difficulty of tampering, although for recent drug use within 5 days, urine tests remain most accurate.

Hair examinations have gained recognition as a potent means for uncovering alcohol and drug consumption. Hair offers an extensive timeline of drug and alcohol use by capturing biomarkers within the fibers of the developing hair shaft. When gathered near the scalp, hair can reveal a detection timeframe of up to about three months for various substances. It's easy to gather, somewhat resistant to tampering, and convenient to transport.
A 1.5-inch sample consisting of roughly 200 hair strands (comparable to the girth of a #2 pencil) nearest to the scalp will yield 100mg of hair, the optimum quantity for both screening and confirmation. For EtG, additional analyses, and/or tests beyond 10 panels, 150mg of the sample is advisable. We advise weighing the sample with a jeweler’s scale. If scalp hair isn't feasible, a similar volume of body hair can be taken. Head hair pertains solely to scalp hair, while body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary step involving the incorporation of a sample into a lab’s system. This covers verifying the sample’s proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and filling in any missing data not covered by an electronic chain of custody system.
Screening entails a rapid initial assessment for substances of abuse. Although Screening is an economical way to exclude drug use in most samples, a positive screen necessitates confirmation to be valid legally. Samples that test presumptively positive during Screening require further confirmation.
If a sample shows presumptive positivity at the Screening stage, additional hair is taken from the initial batch and prepped for Extraction. At this phase, drugs are isolated from hair at a considerably lower concentration compared to other methods (e.g., urine or oral fluid), which makes hair drug screening a challenging methodology to execute.
Confirmation of a positive screening outcome occurs via GC/MS, GC/MS/MS, or LC/MS/MS. All samples that show presumptive positivity are washed prior to final confirmation if needed. From Accessioning through Confirmation, the whole lab process is assessed under both the CAP (College of American Pathologists) Hair classification and accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: While commonly termed "hair follicle tests", the examination focuses on the hair shaft 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.
