Accredited Drug Testing offers thorough hair follicle drug examinations in Agua Nueva, Texas. For those needing a hair drug or alcohol test, we excel in hair analysis, with facilities present in every city nationwide capable of conducting these tests. Typically, 1.5 to 2 inches of hair from the head or body suffice for analysis, which can detect drugs, alcohol/ETG, or other specialized tests.
Recently, hair follicle tests have increasingly become a standard method for drug screening. Many organizations, judicial systems, and substance abuse experts favor hair tests over urine analysis. Those with zero-tolerance drug policies, courts, and probationary individuals often undergo this test due to its advantage of an extended detection period of up to 90 days, along with an irrefutable process. Yet, urine tests remain most accurate for identifying drug use within 5 days.

Hair testing is increasingly regarded as a robust method for identifying drug and alcohol consumption. Hair can capture long-term data on alcohol and drug usage by embedding biomarkers within the fibers of the hair strand as it grows. When collected near the scalp, hair can offer a detection window of up to roughly three months for alcohol and drugs. The collection process is straightforward, resistant to tampering, and easy to transport.
A 1.5-inch segment consisting of about 200 hair strands (similar in size to a #2 pencil) near the scalp will yield 100mg of hair, which is optimal for both screening and confirmation. For EtG extensions, additional tests, or those exceeding 10 panels, a 150mg sample is advised. It's recommended to use a jeweler’s scale for precise measurement. If scalp hair is not available, the same amount of body hair can be utilized. "Head hair" refers exclusively to scalp hair, whereas "body hair" encompasses all other hair types (such as facial or axillary hair).
Process Overview
The lab processing of a drug test result involves four crucial stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial entry of the sample into the lab's system. It involves ensuring the sample was appropriately sealed and shipped, allocating a random LAB (Laboratory Accessioning Number), and finishing additional data entry not provided by an electronic chain of custody system.
Screening constitutes a preliminary check for drug use. Although it offers a cost-effective approach to exclude drug usage in most samples, a positive result from screening needs confirmation to be valid in legal settings. Presumptively positive screening samples require further confirmation.
In cases of presumptive positivity during Screening, additional hair is extracted from the original specimen and prepared for Extraction. During Extraction, drugs are retrieved from hair at concentrations that are much lower than other methods (e.g., urine or oral fluid), making hair drug screening an intricate process.
Confirmation of a positive screening result is performed through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples that test presumptively positive undergo a cleaning process prior to confirmation as needed. The comprehensive lab procedure from Accessioning to Confirmation is assessed under the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: Though commonly termed "hair follicle tests," these tests analyze the hair strand rather than the hair follicle beneath the scalp.
Comparatively, hair follicle testing in Agua Nueva, TX stands out over traditional urine analysis.

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.
