Offering comprehensive hair follicle drug evaluations in Tryon, Oklahoma, Accredited Drug Testing excels in both hair and alcohol testing with nationwide testing centers. Generally, either 1.5 to 2 inches of head or body hair is needed. Hair testing can detect drugs, alcohol/ETG, or accommodate specific testing needs.
Increasingly, hair follicle tests have supplanted traditional methods for drug screenings. Employers and legal systems now favor hair testing for its enhanced detection period of up to 90 days, offering a nearly foolproof collection process. Although hair tests excel in long-term detection, urine tests remain more precise within a recent 5-day window.

Hair analysis is regarded as a potent means for identifying drug and alcohol consumption. Hair captures a long-lasting record of alcohol and drug presence by embedding biomarkers within the fibers of the emergent hair strand. Harvested near the scalp, hair can offer a detection period up to roughly 3 months for alcohol and drugs. Hair is easy to gather, less prone to tampering, and simple to transport.
A sample of 1.5 inches consisting of roughly 200 hair strands (similar to a #2 pencil's diameter) next to the scalp yields 100mg, which is the perfect amount for testing and verifying. For EtG testing, add-ons, and/or analysis above 10 panels, it is advised to use 150mg of the sample. It's advisable to weigh the sample using a jeweler’s scale. If scalp hair is absent, an equal volume of body hair can be collected. "Head hair" specifically denotes scalp hair. "Body hair" includes all other hair types (face, underarm, etc.).
Process Overview
The four essential phases in the lab processing of a drug test record are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the primary processing of a specimen into a lab's database. This step verifies proper sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any remaining data entry not managed by an electronic chain of custody system.
Screening is a preliminary rapid assessment for drug misuse. Although Screening is a budget-friendly technique for excluding drug use in most specimens, a positive result must be confirmed for legal admissibility. Samples that are tentatively positive in Screening necessitate secondary verification.
In case a sample tests tentatively positive during Screening, additional hair is extracted from the initial sample and readied for Extraction. Here, drugs are extracted from the hair at significantly lower levels than other techniques (e.g., urine or saliva), thus making hair drug analysis the most challenging method to execute.
Verification of any positive screen outcome is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All tentatively positive samples undergo washing before confirmation as necessary. The complete lab process from Accessioning to Confirmation is overseen under both the CAP (College of American Pathologists) Hair verification and the certification to ISO / IEC 17025 criteria.
Advantages of hair drug testing:
Limitations:
Note: Although commonly called "hair follicle tests", the test itself examines the hair strand and not 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.
