Accredited Drug Testing offers comprehensive hair follicle drug testing services in Queen City, Texas. Our expertise in hair testing extends across the nation with facilities ready to conduct hair and alcohol examinations. Generally, 1.5 to 2 inches of crown or body hair is necessary for sampling. Testing options are available for drugs, alcohol/ETG, and other customizable needs.
Recently, many drug testing protocols have incorporated hair follicle analysis over traditional urine tests. This method is favored by employers with zero-tolerance policies, courts, and probation officers due to its extended detection period. A hair follicle test can highlight drug use up to 90 days prior, offering a virtually foolproof collection process. For identifying recent drug use within five days, a urine test remains the most precise.

Hair analysis is now recognized as a significant method for identifying substance and alcohol consumption. Hair offers an extended timeline of substance and alcohol history by encasing biomarkers within the hair strand's fibers. When taken near the scalp, hair can offer a detection timeframe for substances and alcohol of up to around three months. Hair is straightforward to obtain, relatively challenging to tamper with, and simple to mail.
A sample measuring 1.5 inches consisting of approximately 200 hair strands (comparable to a #2 pencil's size) closest to the scalp provides 100mg of hair, which is the perfect sample amount for both screening and confirmation processes. For EtG, additional testing, and/or tests exceeding 10 panels, a sample of 150mg is advised. We suggest using a jeweler’s scale for specimen measurement. In cases where scalp hair isn't accessible, an equivalent volume of body hair might be used. When mentioning head hair, we specifically refer to scalp hair. Body hair encompasses all other hair forms (facial, axillary, etc.).
Process Overview
The key stages in processing a laboratory drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves registering a sample in a lab’s database initially. This involves verifying the sample's proper sealing and transport, assigning a LAN (Laboratory Accessioning Number), and completing any further data required outside of an electronic chain of custody framework.
Screening is the preliminary rapid assessment for drug abuse. Screening serves as a budget-friendly approach to dismiss drug consumption across most samples; however, confirming a positive screen is necessary for legal admissibility. Samples that are preliminarily positive via Screening need a subsequent confirmation.
If a preliminary positive is obtained during Screening, more hair is extracted from the original sample and prepped for Extraction. This stage involves drug removal from hair at concentrations much lower than alternative methods (e.g., urine or saliva), making hair drug screening a particularly challenging technique to conduct.
GC/MS, GC/MS/MS, or LC/MS/MS is employed for confirming any positive screening outcome. All preliminarily positive samples undergo necessary washes before confirmation. The complete laboratory protocol from Accessioning through Confirmation is scrutinized under CAP (College of American Pathologists) Hair certification and ISO / IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: Despite often being called "hair follicle tests", the actual analysis is performed on the hair strand and not on 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.
