In Gonzales, Texas, Accredited Drug Testing offers comprehensive hair follicle drug tests. Specializing in hair analysis for drugs and alcohol, our nationwide centers are equipped to perform these tests, requiring only 1.5 to 2 inches of hair from your head or body. We provide various testing options, including drugs, ETG/alcohol, and other custom analyses.
The popularity of hair follicle testing as a method for drug screening has surged. Preferred by employers, courts, and substance abuse authorities, it is favored over the traditional urine test. Its primary advantage is a longer detection period, capturing drug use up to 90 days past, and the collection process is conducted under observation, making manipulation difficult. Urine tests remain the most accurate for recent drug use detection within a 5-day window.

Hair testing is recognized as a significant resource for identifying drug and alcohol consumption. Hair offers a prolonged timeline of alcohol and drug usage by embedding biomarkers within the strands of growing hair. When extracted near the scalp, hair can offer roughly a 3-month detection range for both alcohol and drugs. Hair is straightforward to collect, somewhat challenging to tamper with, and convenient for transport.
A 1.5-inch hair sample consisting of around 200 strands (roughly the size of a #2 pencil) near the scalp amounts to 100mg, which is the optimal sample size for both screening and confirmation. For EtG, add-ons, and/or analyses exceeding 10 panels, 150mg of the sample is suggested. We advocate weighing the hair sample via a jeweler’s scale. If scalp hair cannot be sourced, an equivalent volume of body hair may be gathered. Note that head hair specifically refers to scalp hair. Body hair denotes all other hair types (facial, axillary, etc.).
Process Overview
The processing of a drug test outcome in the lab encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the preliminary integration of a sample into a laboratory's database. This phase covers the verification that the sample was appropriately sealed and dispatched, allocating a random LAN (Laboratory Accessioning Number), and finalizing any additional data processing not managed by an electronic chain of custody mechanism.
Screening signifies an initial rapid assessment for substance abuse. Though Screening is an economical approach to eliminating drug consumption in most samples, a positive screening result must be validated for legal admissibility. All samples yielding a presumptive positive during Screening require further confirmation.
For samples that are presumptively positive in the Screening stage, additional hair is extracted from the initial sample and set for Extraction. This stage involves retrieving drugs from hair at significantly reduced concentrations compared to other techniques (such as urine or oral fluid), marking hair drug screening as the most challenging method to execute.
Confirmation for any positive screening result is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive specimens undergo a wash before confirmation as necessary. The full laboratory sequence from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Though frequently termed "hair follicle tests", these tests assess the hair strand rather than the follicle underneath 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.
