Accredited Drug Testing offers extensive hair follicle drug testing services in Violet, Texas. If a hair drug or alcohol test is necessary, our expertise in hair testing ensures precise results, and our centers are located across all cities in the U.S. with the capability to conduct hair tests. Generally, you need 1.5 to 2 inches of hair from your crown or body. Hair specimens can be assessed for drugs, alcohol/ETG, or other specialized testing.
Recently, hair follicle drug tests have become a more common method for drug screening. Many employers, courts, and substance abuse specialists prefer hair testing over standard urine tests. Hair tests are favored by zero-tolerance workplaces, courts, and individuals under probation. A key advantage of hair follicle tests is the extended detection time, capable of identifying drug use for up to 90 days, collected under observation, and being extremely hard to tamper with. Nevertheless, for detecting drug use within the past 5 days, urine tests remain the most precise.

Hair testing has become recognized as an effective method for identifying drug and alcohol usage. By trapping biomarkers in its growing fibers, hair provides a longitudinal record of alcohol and drug exposure. When taken near the scalp, hair offers a detection window of up to around three months for alcohol and drugs. Hair collection is straightforward, somewhat challenging to tamper with, and convenient for shipping.
A 1.5-inch sample containing roughly 200 hairs (comparable to the diameter of a #2 pencil) near the scalp yields 100mg, which is ideal for analysis and confirmation. For EtG, additional tests, and/or tests beyond 10 panels, 150mg of hair is advised. The specimen should be weighed using a jeweler’s scale. If scalp hair is not an option, a comparable amount of body hair can be collected. The term "head hair" exclusively refers to scalp hair. "Body hair" encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of drug test results involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial processing stage where a sample is entered into a lab's system. It involves ensuring that the sample is sealed and dispatched correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not supplied by an electronic chain of custody system.
Screening is a preliminary check for substance abuse. While Screening is a cost-efficient means of eliminating drug use in most samples, confirmed results are necessary for legal admissibility. Samples that test presumptively positive during Screening require further confirmation.
If a sample appears positive during Screening, additional hair is extracted from the original specimen for the Extraction stage. Drugs are extracted at much lower concentrations than in methods like urine or oral fluid, rendering hair drug screening one of the most intricate methodologies to execute.
Confirmation of positive results from Screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are washed as required before confirmation. The entire laboratory process from Accessioning through Confirmation is subjected to review by the College of American Pathologists (CAP) Hair designation, as well as accreditation to ISO/IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although often referred to as "hair follicle tests", the test evaluates the hair shaft rather than 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.
