Accredited Drug Testing offers comprehensive hair follicle drug screenings in Howesville, Indiana. Whether you require a hair drug or alcohol evaluation, we're experts in this field and have facilities across all cities nationwide capable of conducting hair tests. Generally, 1.5 to 2 inches of hair on the head's crown or body hair is needed. Hair tests assess for substances like drugs, alcohol/ETG, and offer tailored testing options.
Recently, hair follicle drug tests have become more prevalent in drug testing methodologies. Numerous employers, legal systems, and Substance Abuse experts prefer hair testing over urine tests. This type of testing targets employers with strict drug policies, judicial systems, and individuals under supervision. The main advantage lies in an extended detection window, lasting around 90 days, collected with oversight, and challenging to manipulate. However, for drugs taken within five days, urine testing remains the precise choice.

Hair testing now stands as an influential method for identifying drug and alcohol consumption. Hair retains a prolonged record of drugs and alcohol, trapping biomarkers within the strands' fibers as they grow. When collected near the scalp, hair can detect drugs and alcohol over a roughly three-month period. The collection process is straightforward, the risk of tampering is relatively low, and shipping is uncomplicated.
A 1.5-inch hair sample, roughly 200 strands in thickness (similar to a #2 pencil), closest to the scalp should weigh about 100mg, which is the ideal measurement for both screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, a 150mg specimen is advisable. We suggest using a jeweler’s scale for measuring. If scalp hair is unobtainable, a comparable amount of body hair may be used. "Head hair" specifically refers to scalp hair, whereas "body hair" encompasses all other hair types (such as facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result consists of four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the sample’s initial integration into a lab’s system. This step involves ensuring the sample’s seal and shipping are intact, allocating a random LAN (Laboratory Accessioning Number), and finalizing any pending data entry not covered by an electronic chain of custody system.
Screening is a preliminary test for substances of abuse. While cost-effective to rule out drug use in most samples, a positive result from Screening must be confirmed to be valid in legal proceedings. Any samples testing presumptively positive require further confirmation.
For samples that test presumptively positive during Screening, additional hair is extracted from the initial sample for Extraction. Here, drug extraction from hair occurs at much lower concentrations compared to other methods (such as urine or oral fluid), making hair drug screening the most complex method to execute.
Confirmation of any positive screen is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples are washed as necessary. The complete laboratory process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair certification and ISO / IEC 17025 accreditation standards.

Limitations:
Note: Although commonly termed as "hair follicle tests", the evaluation is made on the hair strand, not on the scalp's hair follicle.

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.
