Accredited Drug Testing provides comprehensive hair follicle drug testing services in Quinlan, Texas. If you're in need of a hair drug or alcohol test, Accredited Drug Testing focuses on hair testing, with facilities nationwide, including in every city, to conduct a hair test. Generally, 1.5 to 2 inches of hair from the head or body is needed. Tests can assess for drugs, alcohol/ETG, or other personalized options.
Recently, drug testing methods increasingly incorporate hair follicle tests. Many employers, legal systems, and substance abuse experts prefer hair tests over traditional urine tests. Hair follicle tests support zero-tolerance policies and probation requirements effectively. The key advantage is a longer detection window, up to 90 days, with supervised collection, making it very hard to falsify. Yet, for detecting recent drug use within 5 days, urine tests remain most reliable.

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair acts as a long-term record of alcohol and drugs, capturing biomarkers within the fibers of the hair as it grows. When taken near the scalp, hair can provide up to nearly a 3-month detection period for alcohol and drugs. Hair is straightforward to collect, challenging to tamper with, and convenient to send.
A 1.5-inch segment of roughly 200 hairs (approximately the width of a #2 pencil) next to the scalp will provide 100mg of hair, which is the optimal sample size for testing and verification. For EtG, supplemental tests, and/or panels exceeding 10, it is suggested to use 150mg of the specimen. We advise measuring the sample with a jeweler’s scale. If head hair is not available, a comparable amount of body hair can be used. When mentioning head hair, it refers exclusively to scalp hair. Body hair includes all other hair types (e.g., facial, axillary).
Process Overview
The primary stages in the laboratory processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial processing of a sample into a lab's system. This process involves verifying the sample's seal and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not included in an electronic chain of custody system.
Screening is a preliminary swift check for drug abuse. Though Screening is an economical method to exclude drug use in most samples, a positive screen must be confirmed for court admissibility. Any samples that are tentatively positive in Screening necessitate further confirmation.
If a sample is tentatively positive during the Screening phase, more hair is extracted from the original specimen and prepped for Extraction. During this stage, drugs are extracted from hair at much lower concentrations than in other techniques (e.g., urine or oral fluid), which makes hair drug screening notably challenging to conduct.
Verification of any positive Screening outcome is done using GC/MS, GC/MS/MS, or LC/MS/MS. All tentatively positive samples are cleaned as needed before Confirmation. The comprehensive lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and follows ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: While commonly called "hair follicle tests", the test analyzes the hair strand and not the 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. 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.
