Accredited Drug Testing offers comprehensive hair follicle drug testing in Creve Coeur, Missouri. For those needing hair drug or alcohol testing, our specialty includes hair examinations, with centers located nationwide ready to perform these tests. Generally, 1.5 to 2 inches of hair from the head or body is required. Hair tests can detect drugs, alcohol/ETG, or other personalized testing options.
In recent times, drug testing methods have increasingly incorporated hair follicle testing. Employers, legal entities, and substance abuse specialists are favoring hair tests over traditional urine examinations. Companies with zero-tolerance for drugs, courts, and individuals on probation see the advantage. The main benefit of hair tests is their extended detection capability, up to 90 days, with supervised collection that’s nearly foolproof. However, for identifying drug use within the last 5 days, urine tests remain more precise.

When you're searching for hair drug testing near me or hair drug testing locations, we provide a simple and convenient process to find a drug and alcohol testing location near you that is certified to provide all of your drug and alcohol testing needs.
Hair examination is now recognized as an effective method for identifying substance and alcohol consumption. It offers an extensive timeline of alcohol and drug usage by encasing biomarkers in the strands of hair as they grow. Hair taken close to the head can reveal about a 3-month window of alcohol and drug presence. This method is easy to perform, harder to tamper with, and convenient to transport.
A sample of 1.5 inches comprising approximately 200 hair strands (similar in size to a #2 pencil) cut nearest to the scalp yields 100mg, which is optimal for both screening and verification. For extended tests like EtG, additional samples, and tests exceeding 10 panels, a 150mg sample is preferable. We suggest measuring the sample on a jeweler’s scale. If head hair is unavailable, an equal quantity of body hair can be collected. When we mention head hair, it pertains strictly to scalp hair. Body hair encompasses other types such as facial or axillary hair.
Process Overview
The lab processing of a drug test outcome involves four critical stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase of processing a specimen into a lab's system. It includes validating that the specimen was properly sealed and shipped, assigning it a random LAN (Laboratory Accessioning Number), and completing any additional data input not supplied by an electronic chain of custody protocol.
Screening is conducted to perform a preliminary check for drug abuse. While it is a cost-efficient approach to eliminate drug usage in most specimens, any positive screening requires confirmation for legal purposes. All presumptive positives from the Screening phase require a follow-up confirmation.
A presumptive positive result in the Screening stage leads to more hair being extracted from the original sample and prepared for Extraction. During this stage, drugs are isolated from hair at much lower concentrations than with other methods (e.g., urine or saliva), which makes hair drug analysis notably challenging.
Verification of positive screening outcomes happens through GC/MS, GC/MS/MS, or LC/MS/MS. All samples that show positive screenings are cleaned before verification if required. The complete lab process from Accessioning to Verification is audited under both the CAP (College of American Pathologists) Hair classification and compliance with ISO / IEC 17025 criteria.

Considerations:
Note: Although commonly labeled as "hair follicle tests", the analysis is performed on the hair strand rather than the scalp's hair follicle.

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.
