Accredited Drug Testing provides thorough hair follicle drug assessments in Wood Heights, Missouri. Specializing in hair and alcohol tests, our centers span all major cities nationwide. Usually, 1.5 to 2 inches of head or body hair is sufficient. Hair samples can be scrutinized for drugs, alcohol/ETG, or tailored testing options.
Lately, hair follicle drug tests have become more prevalent in drug screenings requested by employers, courts, and substance abuse experts over typical urine tests. Ideal for organizations with zero-tolerance drug policies, legal institutions, and probation cases, hair tests offer a longer detection window of up to 90 days, obtained through a monitored process that's hard to falsify. However, for detecting drug use within the past 5 days, urine tests still offer the highest accuracy.

Hair testing has emerged as an effective measure for identifying alcohol and drug consumption. Hair offers a lasting record of substance exposure by trapping biomarkers within the growing hair's fibers. When gathered close to the head, hair can reveal substance use for up to three months. Hair collection is straightforward, harder to alter, and convenient to transport.
A 1.5-inch portion of about 200 hair strands (akin to a #2 pencil's thickness) near the scalp yields 100mg, ideal for analyzing. For tests exceeding 10 panels, EtG, or additional assessments, 150mg of the sample is suggested. We advise using a jeweler's scale for weighing. If head hair is unavailable, body hair can be used as a substitute. When we talk about head hair, it specifically refers to scalp hair. Body hair includes all other types (facial, axillary, etc.).
Process Overview
The laboratory analysis of a drug test result includes four steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the introductory processing of a specimen within a lab’s framework. This verifies that the sample is correctly sealed and shipped, assigns a unique LAN (Laboratory Accessioning Number), and completes necessary data entry if an electronic chain of custody system doesn't provide it.
Screening involves an initial prompt inspection for drug traces. While it is a budget-friendly method to exclude drug presence in most samples, a positive result must be verified for court acceptance. Samples showing preliminary positives in Screening need a subsequent confirmation.
If a sample appears positive during Screening, additional hair is extracted from the sample for Extraction. Here, drugs are isolated from hair, presenting a greater challenge compared to other techniques (e.g., urine or oral fluid), highlighting hair drug screening as the most challenging methodology.
Confirmation of any positive screening outcome uses GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives undergo washing before confirmation if required. The complete lab process from Accessioning to Confirmation undergoes review under both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.
Advantages of hair drug testing:
Limitations:
Note: Though often called "hair follicle tests," these tests analyze 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.
