Accredited Drug Testing offers comprehensive hair follicle testing services in Rockdale, Texas. Whether you need drug or alcohol testing, we are the experts in hair analysis, with locations across all major cities nationwide. Typically, 1.5 to 2 inches of hair from the scalp or body is required. This method screens for drugs, alcohol/ETG, as well as other tailored options.
In the last few years, hair follicle drug testing has become more prevalent. Employers, judicial systems, and substance abuse professionals increasingly favor hair testing over traditional urine tests. Employers with strict drug policies, courts, and probation cases rely on this method for its primary advantage—detecting drug use over an extended period of up to 90 days through observed sample collection, making it nearly foolproof. Nonetheless, for identifying recent drug use within five days, urine tests remain the most reliable.

Hair analysis is recognized as an effective means for identifying substance and alcohol consumption. Hair captures extended-term alcohol and drug history by embedding biomarkers within its strands as they grow. When taken near the scalp, it offers nearly a 3-month detection period for both alcohol and drugs. Hair is easy to gather, challenging to tamper with, and convenient to transport.
A 1.5-inch portion comprising around 200 strands of hair (nearly the width of a #2 pencil) nearest to the scalp provides 100mg of hair, which is the optimal quantity for both evaluation and verification. For EtG, supplementary, and/or tests exceeding 10 panels, 150mg of hair is advisable. We suggest measuring the specimen's weight using a jeweler’s scale. If scalp hair is not available, an equivalent quantity of body hair is acceptable. When discussing head hair, it refers exclusively to scalp hair. Body hair pertains to all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial integration of a sample into a lab’s system. This process checks if the sample was appropriately sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and completes any further data entry beyond what an electronic chain of custody system provides.
Screening is a preliminary rapid assessment for drugs of abuse. Although Screening is an economical method to rule out drug use in most samples, any positive indication must be confirmed for court admissibility. Any samples that are initially positive in Screening need follow-up confirmation.
When a sample shows a preliminary positive in the Screening stage, more hair is drawn from the set sample and prepared for Extraction. This stage involves drug extraction from hair in much lower concentrations compared to other techniques (e.g., urine or oral fluid), rendering hair drug screening the most challenging method.
Confirmation of any positive screening result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation if necessary. The complete lab routine from Accessioning to Confirmation is overseen under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

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.
