In Hazelwood, Missouri, Accredited Drug Testing offers thorough hair follicle drug testing services. Specializing in hair drug or alcohol tests, we provide testing facilities in all cities nationwide capable of carrying out a hair test. Typically, you'll need 1.5 to 2 inches of hair on your head or body for the test, which can identify drugs, alcohol/ETG, and other tailored testing options.
Over the years, the demand for hair follicle drug tests has risen in drug testing methods. Employers, courts, and Substance Abuse professionals often opt for hair tests over typical urine tests. This method is favored by those enforcing zero-tolerance drug policies. Hair follicle tests boast a longer detection period, up to 90 days, and are challenging to manipulate. However, urine tests remain superior for detecting recent drug use within the last 5 days.

Hair testing is increasingly recognized as a robust method for identifying drug and alcohol consumption. Hair offers a comprehensive timeline of alcohol and drug use by embedding biomarkers in the strands' fibers. When gathered near the scalp, hair can reveal approximately a 3-month timeframe of alcohol and drug usage. Hair collection is straightforward, relatively tamper-proof, and convenient for shipping.
Obtaining a 1.5-inch length of roughly 200 hair strands (akin to a #2 pencil) nearest to the scalp yields 100mg of hair, optimal for screening and confirmation. For EtG, additional tests, and examinations exceeding 10 panels, a 150mg specimen is advised. We suggest weighing the sample on a jeweler's scale. If scalp hair is inaccessible, a comparable amount of body hair may be used. Head hair strictly refers to scalp hair, while body hair encompasses all other hair types (e.g., facial, axillary).
Process Overview
The four core phases in processing a lab drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary processing of a sample within a lab's system. This step ensures proper sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and finalizes any extra data entry absent from an electronic chain of custody system.
Screening includes an initial rapid evaluation for drugs of abuse. Although Screening offers a cost-efficient method to negate drug use in most samples, courts require confirmation for any positive screen. Therefore, all samples indicated as presumptively positive in Screening must undergo secondary confirmation.
In cases where a sample preliminarily tests positive during Screening, additional hair from the original sample is prepared for Extraction. At this juncture, drugs are extracted from hair at significantly lower concentrations than in other methods (e.g., urine or oral fluid), underscoring hair drug screening's complexity.
Positive Screening results undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed before confirmation as necessary. The complete process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standard accreditation.
Advantages of hair drug testing:
Limitations:
Note: Although often termed as "hair follicle tests", these tests examine the hair strand 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.
