Accredited Drug Testing provides comprehensive hair follicle drug testing services in Katy, Texas. If you're in need of a drug or alcohol test via hair sample, Accredited Drug Testing is proficient in this method with facilities available across Nationwide cities to administer these tests. Typically, a sample requires 1.5 to 2 inches of hair from the head or other body parts. Hair tests can determine drug, alcohol/ETG use, or be tailored for specific tests.
Over the years, the inclusion of hair follicle drug tests in drug screening processes has surged. Many employers, judicial systems, and Substance Abuse professionals opt for hair drug tests over conventional urine tests. This test is crucial for employers with stringent drug policies, courts, and parolees. Its main advantage is a prolonged detection window for drug use, usually up to 90 days, collected under supervision, making it highly cheat-resistant. Nonetheless, urine tests remain unparalleled for detecting recent drug use within the past 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 tests are recognized as an effective method for uncovering drug and alcohol consumption. Hair captures a prolonged record of alcohol and other drug intake by embedding biomarkers within its fibers. When harvested from near the scalp, hair can indicate substance use over approximately a three-month span. Collection of hair is straightforward, tricky to tamper with, and simple to transport.
A 1.5-inch hair sample comprising roughly 200 strands (akin to the thickness of a #2 pencil) closest to the scalp yields 100mg, which is the optimal amount for both screening and confirmation. For tests including EtG, additional parameters, and those exceeding 10 panels, 150mg of hair is advised. We suggest measuring the sample with a jeweler’s scale. Should scalp hair be absent, a similar quantity of body hair may be used. When referencing head hair, this pertains solely to scalp hair. Body hair encapsulates all other hair types (such as facial, axillary, etc.).
Process Overview
The lab processing of drug test outcomes involves four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the primary integration of a sample into a lab’s database. This process ensures the sample was appropriately sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data entry absent in an electronic chain of custody system.
Screening provides an initial rapid assessment for substance abuse. Although Screening is a cost-efficient method to dismiss drug use in the majority of cases, a positive result requires confirmation to hold up in legal settings. Samples that present as presumptively positive during Screening necessitate further confirmation.
In instances of presumptive positivity in Screening, additional hair is processed from the original sample and prepped for Extraction. During Extraction, substances are retrieved from hair at a significantly lower concentration compared to alternative methods (such as urine or oral fluid), highlighting hair drug screening as the most challenging method to execute.
Confirmation of any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that initially appear positive undergo washing before confirmation as necessary. The entire lab process from Accessioning to Confirmation is evaluated in compliance with both the CAP (College of American Pathologists) Hair guidelines and the accreditation to ISO / IEC 17025 standards.
The benefits of hair drug testing include:
Drawbacks:
Note: While often termed "hair follicle tests", the analysis is performed on the hair strand itself and 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.
