Accredited Drug Testing offers comprehensive hair follicle drug testing solutions in Granger, Iowa. If you're in need of a hair drug or alcohol analysis, our expertise lies in hair testing, with centers across all U.S. cities capable of conducting these tests. Typically, 1.5 to 2 inches of hair from the head's crown or body are required. Hair tests provide analysis for drugs, alcohol/ETG, or various tailored testing options.
Lately, drug testing methods have increasingly featured hair follicle tests. Employers, courts, and Substance Abuse professionals often opt for hair over urine tests. Especially useful for those with zero-tolerance policies, the primary advantage of hair follicle tests is their extended drug use detection window of up to 90 days. Conducted under observation, these tests are practically tamper-proof. However, urine tests remain best for identifying drug use within the past 5 days.

Hair analysis is recognized as a potent instrument for identifying alcohol and drug consumption. Hair retains a prolonged record of alcohol and drug presence by capturing biomarkers within the fibers of the developing hair strand. When gathered near the scalp, hair can offer a detection timeframe of up to around 90 days for alcohol and drugs. Hair collection is straightforward, somewhat resistant to tampering, and easy to transport.
A 1.5-inch segment consisting of about 200 hair strands (roughly the diameter of a #2 pencil) nearest to the scalp will yield 100mg of hair, the optimal amount for both screening and confirmation. For EtG, additional analyses, and/or tests exceeding 10 panels, a specimen of 150mg is advised. It's recommended to measure the specimen using a jeweler's scale. If scalp hair is not available, a similar amount of body hair may be used. "Head hair" refers exclusively to scalp hair, while "Body hair" encompasses all other types (e.g., facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test involves four essential stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary incorporation of a sample into a lab's system. This process includes confirming that the sample was appropriately sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any additional information entry that isn't covered by an electronic chain of custody system.
Screening involves a preliminary rapid assessment for addictive substances. While Screening is an economical means to eliminate drug usage in most samples, a positive finding needs to be verified to be admissible in legal proceedings. Samples that yield a presumptive positive during Screening require a subsequent confirmation.
If a specimen shows a presumptive positive during Screening, more hair is extracted from the original sample and prepared for Extraction. During this phase, drugs are retrieved from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), making hair drug testing a challenging method to execute.
The Confirmation of any positive Screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Any presumptive positive samples undergo washing prior to Confirmation as necessary. The entire lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.
Advantages of hair drug testing:
Limitations:
Note: Despite often being termed "hair follicle tests", the analysis focuses on 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.
