In St. Robert, Missouri, Accredited Drug Testing offers comprehensive hair follicle drug tests. Whether it's for drugs or alcohol, our expertise lies in hair testing with centers across the nation. Typically, 1.5 to 2 inches of hair from the head is required, but body hair can also be used. These tests can detect drugs, alcohol/ETG, among other tailored options.
Recently, using hair follicle tests for drug detection has gained traction. More employers, courts, and substance abuse experts prefer hair tests to urine tests. These tests cater to zero-tolerance policies, courts, and probation cases. They offer a longer detection period of up to 90 days, with observed collection, making it resistant to tampering. However, for detecting recent substance use within five days, urine tests remain most accurate.

The use of hair testing has gained traction as an effective method for identifying alcohol and drug consumption. The fibers in growing hair strands capture biomarkers, offering a prolonged record of substance use. When the sample is taken near the scalp, it can offer a detection window of roughly 3 months for both alcohol and drugs. Hair collection is straightforward, relatively tamper-resistant, and hassle-free to transport.
An ideal screening and confirmation sample consists of a 1.5-inch segment from approximately 200 strands of hair, equivalent to the thickness of a #2 pencil, yielding about 100mg of hair. For EtG, add-ons, or testing exceeding 10 panels, 150mg of the sample is advisable. Utilizing a jeweler’s scale for weighing the sample is suggested. In the absence of scalp hair, a similar quantity of body hair can be collected. The term “head hair” specifically refers to scalp hair, while “body hair” includes all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four main steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase of handling a sample into a lab’s system. It involves verifying the sample's proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and inputting any additional data not included via an electronic chain of custody system.
Screening is a preliminary assessment for substances of abuse. While Screening cost-effectively rules out drug use in most samples, any positive results must be confirmed for legal admissibility. Presumptively positive samples in Screening require further confirmation.
For samples presumptively positive during Screening, more hair is extracted from the original sample and readied for the Extraction phase. Here, drugs are separated from hair at a significantly lower concentration compared to other methods (e.g., urine or oral fluid), explaining the complexity of hair drug screening.
Any positive screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS methods. Before confirmation, presumptive positive samples undergo washing as necessary. The entire lab process is scrutinized from Accessioning through Confirmation, encompassing both the CAP (College of American Pathologists) Hair designation and adherence to ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Despite the common term "hair follicle tests," the analysis focuses on 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.
