Accredited Drug Testing offers comprehensive hair follicle drug testing services in Cary, Illinois. Specializing in hair and alcohol testing, we have facilities nationwide, including Cary, to conduct hair tests. Typically, 1.5 to 2 inches of hair from the head or body is required. Hair samples can be tested for drugs, alcohol/ETG, and other specific needs.
In recent times, hair follicle drug testing has become increasingly common for drug screening. It is often preferred by employers, courts, and substance abuse professionals over traditional urine tests. This method is favored by those with strict no-drug policies, including courts and parole authorities. One of the significant advantages is its longer detection period of up to 90 days, which, along with direct observation collection, makes it nearly foolproof. However, for detecting recent drug use within five days, urine tests maintain accuracy.

The utilization of hair testing has emerged as an effective method for detecting drug and alcohol consumption. Hair retains a long-term record of drugs and alcohol use by incorporating biomarkers within the fibers of the developing hair strands. Hair collected near the scalp can provide a detection window for alcohol and drugs lasting up to roughly 90 days. This testing method is straightforward to collect, somewhat resistant to tampering, and simple to transport.
A sample measuring 1.5 inches, consisting of approximately 200 hair strands (similar in size to a #2 pencil) taken closest to the scalp, yields 100mg, which is the optimal sample amount for both screening and corroboration. For tests like EtG, add-ons, or the ones exceeding 10 panels, a specimen quantity of 150mg is advised. It is best to weigh the specimen with a jeweler's scale. Should scalp hair be unavailable, an equivalent quantity of body hair can be collected. When mentioning head hair, it refers exclusively to scalp hair. Body hair encompasses all other types of hair (e.g., facial, axillary).
Process Overview
The four primary stages in the laboratory processing of drug test results encompass Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial handling of a sample into a laboratory's system. This step involves confirming that the sample is properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and performing supplemental data entry not covered by an electronic chain of custody system.
Screening involves a preliminary rapid check for substances of abuse. While it is a cost-efficient means to rule out drug use in most samples, a positive screen requires confirmation for legal admissibility. Any samples with a presumptive positive result in Screening must undergo secondary validation.
If a sample shows a presumptive positive result during the Screening stage, additional hair is extracted from the initial sample and prepared for Extraction. At this stage, drugs are extracted from hair at a notably lower concentration than with other methods (like urine or oral fluid), making hair drug testing one of the most challenging methodologies to conduct.
Confirmation of any positive result from screening is achieved using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptively positive samples undergo washing before confirmation as necessary. The full laboratory procedure from Accessioning to Confirmation undergoes review in accordance with both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Often called "hair follicle tests", the actual analysis is performed on the hair strand, not on the scalp follicle.

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.
