Accredited Drug Testing provides comprehensive hair follicle drug tests in Troy, Missouri. If you're looking for a hair drug or alcohol test, Accredited Drug Testing is a specialist in this area, with facilities in every city across the country that conduct hair testing. Typically, 1.5 to 2 inches of hair from the head's crown or body can be tested. These hair tests can evaluate drugs, alcohol/ETG, or other specialized hair testing requests.
In recent times, drug testing methods have increasingly incorporated hair follicle tests. Numerous employers, courts, and Substance Abuse specialists are opting for hair drug tests over traditional urine tests. Employers with zero-tolerance drug policies, legal systems, and individuals on probation commonly use hair follicle tests. The significant advantage of this testing method is its extended detection window, generally up to 90 days, conducted under observation, making it nearly impossible to manipulate. However, for detecting drug use within the last 5 days, urine testing remains the most precise.

Hair analysis has emerged as an effective instrument for identifying drug and alcohol use. Hair captures a historical record of alcohol and other drugs by ensnaring biomarkers within the fibers of the developing hair shaft. When acquired near the scalp, hair provides an approximately 3-month timeframe for detecting alcohol and other drugs. Hair is easy to gather, relatively hard to tamper with, and simple to transport.
A 1.5-inch segment of around 200 strands of hair (roughly the thickness of a #2 pencil) closest to the scalp will yield 100mg of hair, the optimal sample for both screening and confirmation. For EtG, add-ons, and/or tests beyond 10 panels, a 150mg specimen is advisable. It is recommended to weigh the sample using a jeweler’s scale. If scalp hair is not available, an equivalent amount of body hair may be used. When mentioning head hair, it specifically refers to scalp hair. Body hair pertains to all other hair types (facial, underarm, etc.).
Process Overview
The lab process for a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into the lab’s system. This involves verifying the sample's seal and proper shipment, designating a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry missing from an electronic chain of custody system.
Screening is a preliminary rapid assessment for misuse of drugs. While Screening is cost-efficient for excluding drug use in most samples, a positive screen requires confirmation for legal acceptability. Any samples that exhibit presumptive positivity in Screening necessitate secondary confirmation.
Should a sample show presumptive positivity in the Screening phase, additional hair is extracted from the original specimen for preparation during Extraction. In this stage, drugs are isolated from hair at notably reduced concentrations compared to other methods (e.g., urine or oral fluid), which explains why hair drug screening is the most challenging method to execute.
Verification of any positive screening outcome is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples exhibiting presumptive positivity undergo washing before confirmation as required. The entire lab procedure from Accessioning to Confirmation is scrutinized under both CAP (College of American Pathologists) Hair guidelines and in compliance with ISO/IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Though frequently termed as "hair follicle tests", the actual test analyzes 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.
