For comprehensive hair follicle drug testing in Hico, Texas, turn to Accredited Drug Testing. Whether testing for drugs or alcohol, our specialization in hair testing connects you with centers nationwide ready to assist. With just 1.5 to 2 inches of hair from the scalp or body, substances like drugs and alcohol/ETG are detectable, offering flexible hair testing choices tailored to your needs.
Hair follicle drug tests have become increasingly prevalent for substance detection in recent years. Preferred over urine tests by employers, courts, and Substance Abuse experts, these tests benefit from better reliability. With a zero-tolerance policy, employers trust hair tests, as they span a detection period of up to 90 days, are collected with oversight, and are incredibly hard to manipulate. On the other hand, urine tests are still favored for catching recent drug use within five days.

Hair assessments are now recognized as an effective method for detecting substance and alcohol usage. The hair captures a lasting record of these substances by embedding biomarkers within the strands' fibers as they grow. Proximity to the scalp during collection allows hair to offer almost a three-month span of detection for both alcohol and other substances. The collection process is straightforward, with minimal risk of tampering and ease of transport.
Acquiring a sample of hair measuring 1.5 inches and comprising around 200 strands (comparable to a #2 pencil) directly from the scalp yields 100mg, which is the optimal amount for both initial screening and follow-up confirmation. For EtG, additional tests, or panels exceeding ten, a specimen of 150mg is advisable. It's beneficial to measure the sample's weight using a jeweler's scale. In instances where scalp hair isn't available, an equivalent volume of body hair may be substituted. It's important to note that references to head hair pertain exclusively to scalp hair, while body hair encompasses all other forms (such as facial or axillary).
Process Overview
The laboratory processing involved in analyzing a drug test result incorporates four critical stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary integration of a sample into a lab's processing system. This step includes confirming that the sample was correctly sealed and transported, assigning a Laboratory Accessioning Number (LAN), and completing any outstanding data fields not addressed in a digital chain of custody protocol.
Screening functions as a preliminary, rapid assessment for illicit substances. Although it's an economical method to exclude drug usage in most samples, a positive finding here necessitates a confirmatory test to uphold legal scrutiny. Any samples showing initial positive results in this phase must undergo further verification.
In cases of preliminary positive results during Screening, additional hair from the original batch is used for the Extraction phase. Here, substances are isolated from the hair at much lower concentrations compared to other methods (like urine or saliva testing), highlighting the complexity of hair drug analysis.
Final Confirmation of positive screenings is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All initially positive samples are cleaned before final confirmation, as the process demands. The complete procedural chain, from Accessioning to Confirmation, is scrutinized per both the CAP (College of American Pathologists) Hair classification and accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Often termed as "hair follicle tests", the analysis is performed on the hair strands and not on 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.
