Accredited Drug Testing provides comprehensive hair follicle drug tests in Holland, Michigan. If a hair drug or alcohol test is necessary, they specialize in hair testing with locations available in all cities Nationwide. Typically, 1.5 to 2 inches of head hair or body hair is needed. Hair tests can screen for drugs, alcohol/ETG, or other tailored testing options.
In recent years, drug testing methods increasingly involve hair follicle tests. Employers, courts, and Substance Abuse professionals often prefer hair tests over traditional urine tests. Hair follicle tests accommodate zero-tolerance policies, court cases, and probationary monitoring. Their primary advantage lies in a detection window of up to 90 days, with observed collection ensuring minimal cheating. However, urine tests remain most precise for recent drug use (within 5 days).

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 testing is now widely regarded as a robust method for identifying drug and alcohol consumption. Hair captures a comprehensive long-term record of alcohol and drug use by embedding biomarkers within the fibers of the growing hair strand. When sampled near the scalp, hair can offer a detection timeframe of approximately 3 months for both alcohol and drugs. The collection process is straightforward, not easily tampered with, and convenient for transportation.
A sample measuring 1.5 inches with around 200 strands of hair (comparable to the thickness of a #2 pencil) taken nearest the scalp provides 100mg of hair, which is the optimal amount for preliminary and confirmatory testing. For additional tests such as EtG or those exceeding 10 panels, a specimen weight of 150mg is suggested. We advise using a jeweler’s scale to weigh the specimen. If scalp hair is not available, a similar quantity of body hair may be used. The term head hair specifically refers to scalp hair, whereas body hair encompasses all other forms (facial, axillary, etc.).
Process Overview
There are four fundamental stages in processing a drug test result in the lab: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial incorporation of a sample into the lab's system. This stage includes ensuring that the sample was properly sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and undertaking any additional data entry not integrated by an electronic chain of custody system.
Screening carries out an initial rapid assessment to identify drug presence. While this is a cost-efficient method to eliminate drug use in the majority of samples, any positive findings in Screening must be validated for court admissibility. Samples testing presumptively positive in Screening require further confirmation.
Should a sample test presumptively positive at the Screening phase, additional hair is prepared from the initial sample for Extraction. In this phase, drugs are separated from hair at a much lower concentration than in other methods (e.g., urine or oral fluid), which is why hair drug screening presents significant challenges.
Any positive results from screening undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleansed before confirmation if necessary. The comprehensive laboratory process, from Accessioning to Confirmation, is subject to review in accordance with the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 certification standards.
Advantages of hair drug testing:
Limitations:
Note: Frequently termed "hair follicle tests", the analysis targets the hair strand rather than 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.
