Accredited Drug Testing offers extensive hair follicle drug screening services in Bexar, Alabama. For those requiring a hair or alcohol analysis, we specialize in these tests, boasting nationwide centers capable of conducting them. Typically, 1.5 to 2 inches of hair from the head or body is needed. Our hair assays can detect drugs, ETG/alcohol, or other tailored testing options.
Over the past few years, hair follicle testing has become a more common method for drug assessments. A growing number of employers, judicial systems, and Substance Abuse experts now prefer this method over traditional urine analysis. Hair tests are favored by entities with strict no-drug policies, legal courts, and probation departments. The main advantage is its extended detection window, which can last up to 90 days, involves an observed collection, and is nearly impossible to tamper with. However, for detecting recent use within five days, urine tests remain the most precise.

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 analysis has emerged as an effective means to uncover both drug and alcohol consumption. Hair captures a prolonged history of substance use by embedding biomarkers within the growing strand's fibers. When collected near the scalp, it offers a detection span of nearly three months for alcohol and other substances. This sampling method is straightforward, challenging to tamper with, and convenient for transport.
A specimen consisting of a 1.5-inch cut of approximately 200 hairs (roughly the girth of a #2 pencil) closest to the scalp yields 100mg, the preferred amount for both screening and verification. For EtG, extensions, and tests exceeding 10 panels, a 150mg specimen is advisable. It is recommended to utilize a jeweler's scale for precise weighing. Should scalp hair not be available, an equivalent volume of body hair is acceptable. In reference to head hair, this pertains solely to scalp hair. Body hair denotes other varieties (facial, axillary, etc.).
Process Overview
The lab analysis of a drug test follows four pivotal stages: Accessioning, Screening, Extraction, and Verification.
Accessioning entails the initial incorporation of a sample into the lab's system. This phase verifies the sample's proper sealing and transport, generates a random LAN (Laboratory Accessioning Number), and completes any additional data processing absent from an electronic chain of custody framework.
Screening executes a preliminary scan for substance misuse. Although Screening serves as an economical measure to exclude drug use in most samples, any positive outcome necessitates confirmation for court admissibility. Presumptively positive samples in Screening need further confirmation.
In cases of presumptive positivity during Screening, additional hair is extracted from the original specimen for Extraction. During this process, substances are retrieved from hair at significantly lower densities than alternative methodologies (such as urine or oral fluid testing), underscoring why hair drug analysis remains a complex procedure.
Verification of any positive results in Screening is achieved using GC/MS, GC/MS/MS, or LC/MS/MS methodologies. Presumptive positive specimens undergo washing prior to Verification as required. The comprehensive lab sequence from Accessioning to Verification is examined through both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation.
Benefits of Hair Analysis for Drugs:
Drawbacks:
Note: Although colloquially termed as "hair follicle analyses", the examination focuses on the hair strand, not 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.
