Accredited Drug Testing offers thorough hair follicle drug tests in St. Johns, Michigan. Whether you need to test for drugs or alcohol through hair, we have specialized centers available Nationwide for such purposes, including in all major cities. With at least 1.5 to 2 inches of hair from your head or body, our tests can identify drugs, alcohol/ETG, and other specific hair tests needed.
Recently, hair follicle drug tests have grown in popularity for drug screening. Employers, courts, and Substance Abuse professionals are increasingly opting for this method over traditional urine tests. Hair tests benefit those with zero-tolerance drug policies, probation cases, and more due to their 90-day detection capability, observed collection, and resistance to tampering. However, urine tests remain more accurate for detecting recent drug use within five days.

Testing using hair is now recognized as a strong method for identifying alcohol and drug usage. Hair captures a comprehensive record of substance use by embedding biomarkers within its fibers as it grows. Harvested near the scalp, hair reveals a detection period of up to approximately three months for alcohol and drugs. The collection process is straightforward, challenging to tamper with, and easy to transport.
A sample measuring 1.5 inches with about 200 hair strands (comparable to the thickness of a #2 pencil) closest to the scalp yields 100mg, an ideal quantity for testing. For EtG and tests exceeding 10 panels, a specimen of 150mg is advisable. Using a calibrated scale to weigh the specimen is suggested. If scalp hair cannot be sourced, an equivalent amount of body hair is acceptable. 'Head hair' refers exclusively to scalp hair, while 'body hair' encompasses other types of hair (such as facial or axillary).
Process Overview
The laboratory processing of a drug test result involves four main stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is initially processed into the laboratory's system. This step ensures that the sample was appropriately sealed and transported, assigns a unique LAN (Laboratory Accessioning Number), and completes any additional data input not captured by an electronic chain of custody system.
The Screening phase provides a preliminary review for substances of abuse. Though Screening serves as a cost-efficient means to eliminate drug use for most samples, any positive screening test requires confirmation to be court-admissible. Samples suggesting a positive result during Screening necessitate further verification.
Should a sample appear positive after Screening, additional hair is sourced from the original collection for Extraction. At this stage, drug elements are extracted from hair at significantly lower levels compared to other methods (e.g., urine or saliva), affirming that hair drug testing is the most challenging process to conduct.
Confirmation for any positive screening outcome is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing before confirmation as necessary. The complete lab process, from Accessioning to Confirmation, is examined under both the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation.

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.
