Accredited Drug Testing provides comprehensive hair follicle analysis in Mertzon, Texas. If a hair drug or alcohol screening is required, we specialize in these tests, with locations nationwide ready to conduct them. A minimum of 1.5 to 2 inches of head or body hair is usually necessary. Hair testing can uncover substances, alcohol/ETG, or offer bespoke options.
In recent years, the trend for screening has shifted towards hair follicle drug testing. Employers, courts, and substance abuse experts increasingly favor it over traditional urine analysis. Hair tests benefit zero-tolerance workplaces, legal systems, and probationers, thanks to their extended detection period—up to 90 days—and difficult-to-tamper characteristics. Nevertheless, urine tests remain unmatched for detecting recent usage within the last five days.

When you're searching for hair drug testing near me or hair drug testing locations, we provide a simple and convenient process to find a drug and alcohol testing location near you that is certified to provide all of your drug and alcohol testing needs.
Hair testing is widely regarded as an effective method for identifying drug and alcohol usage. Hair retains a lengthy record of alcohol and other substances by capturing biomarkers within the fibers of the growing hair shaft. Collected near the scalp, hair may offer a detection timeframe of up to roughly 90 days for alcohol and various drugs. It is easy to collect, relatively resistant to tampering, and convenient to ship.
A 1.5-inch portion comprising around 200 strands of hair (similar in size to a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal sample size for analysis and verification. For EtG, additional testing, and/or examinations beyond 10 panels, 150mg of the sample is advisable. Use of a jeweler’s scale is suggested for specimen measurement. If scalp hair cannot be obtained, a comparable amount of body hair is an alternative. By head hair, we mean scalp hair only. By body hair, we refer to all other hair types (facial, axillary, etc.).
Process Overview
The lab processing of drug test outcomes includes the following four core steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary processing of a sample into a laboratory’s system. It entails confirming that the sample was correctly sealed and transported, assigning an arbitrary LAN (Laboratory Accessioning Number), and finishing any needed data input absent from an electronic chain of custody system.
Screening is an initial swift assessment for drugs of abuse. While it is a cost-efficient approach to exclude drug consumption in most samples, a positive screening must be verified to be admissible in legal proceedings. Presumptively positive samples in Screening necessitate a secondary confirmation.
If a sample tests presumptively positive during Screening, more hair is extracted from the original sample and prepared for Extraction. In this stage, drugs are withdrawn from hair at significantly lower levels than in other methods (e.g., urine or oral fluid), highlighting why hair drug screening is the most challenging methodology to execute.
Confirmation of any positive screening outcome is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples are washed as required. The whole laboratory procedure from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair categorization and accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Even though commonly called "hair follicle tests", the analysis targets the hair shaft and not the hair 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.
