Accredited Drug Testing offers comprehensive hair follicle drug screening services in Hayti, Missouri. Whether it's a drug or alcohol test you require, we excel in hair testing, with locations available throughout every city in the nation ready to conduct these tests. Typically, 1.5 to 2 inches of hair from the crown or other body parts is sufficient for testing. Our hair tests can detect drugs, alcohol/ETG, or can be customized to meet other hair testing needs.
In recent years, hair follicle drug testing has become a preferred method among professionals for conducting drug tests. Many employers, judicial systems, and substance abuse counselors choose hair drug tests over the standard urine method. Employers with zero-tolerance drug policies, court systems, and those on probation rely on these tests for their benefits, like a detection period spanning up to 90 days, an observed collection method, and minimized cheating risk. However, when testing for recent drug use under 5 days, urine tests remain the most precise.

Hair analysis has become recognized as a robust method for identifying drug and alcohol consumption. Hair can capture a historical record of alcohol and substances by embedding biomarkers within the strands of hair as it grows. When obtained near the scalp, hair can offer a detection timeframe of up to about three months for identifying alcohol and other substances. The collection process for hair is straightforward, is less prone to tampering, and is convenient for transport.
A sample measuring 1.5 inches comprising roughly 200 hair strands (around the width of a #2 pencil) nearest to the scalp yields 100mg, which is the optimal sample size for analysis and verification. For additional panels like EtG, or testing above 10 panels, a specimen size of 150mg is suggested. It is advisable to use a jeweler’s scale to weigh the sample. Should scalp hair not be accessible, a similar quantity of body hair is acceptable. "Head hair" specifically refers to scalp hair, whereas "body hair" denotes other hair types (such as facial and axillary).
Process Overview
The primary stages in the lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Certification.
During Accessioning, the sample is initially integrated into a laboratory’s systems. This step encompasses checking the sample for proper sealing and shipping, generating a random LAN (Laboratory Accessioning Number), and finalizing any further data input not available through an electronic chain of custody system.
Screening entails an initial swift evaluation for abusive substances. Although Screening is a budget-friendly method to discard drug use in most samples, a positive result must be validated to be valid in court. Any samples with a presumptive positive during Screening necessitate further confirmation.
If a sample shows presumptive positivity in the Screening phase, more hair is extracted from the original sample and set up for Extraction. In this phase, substances are isolated from hair at a considerably lower concentration compared to other techniques (like urine or oral fluid), highlighting why hair drug analysis is the most challenging procedure to execute.
Validation of any positive Screening result takes place using GC/MS, GC/MS/MS, or LC/MS/MS. Samples marked presumptive positive undergo washing pre-confirmation when required. The full laboratory journey from Accessioning to Confirmation is assessed under both the Hair specification by CAP (College of American Pathologists) and the compliance to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although frequently mentioned as "hair follicle tests", the actual analysis observes the hair strand instead of the follicle beneath the scalp.

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.
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.

I needed a quick drug test for visitation with my children. I called at 6am they answered and set me up with a place a couple miles from my house to go get the test done, that was on Wednesday, I had the results on Friday afternoon and was able to see my kids on Saturday. Thank you for the help!
