Accredited Drug Testing offers comprehensive hair follicle drug testing in Gainesville, Texas. For those in need of hair drug or alcohol screening, our expertise ensures precise hair analysis, with facilities located in every major city across the nation. Typically, 1.5 to 2 inches of hair from the head or body is required. Our hair tests can screen for drugs, alcohol/ETG, or be tailored for specific needs.
The hair follicle testing method has gained popularity in recent years for drug detection. A growing number of employers, judicial systems, and substance abuse experts are opting for hair tests over traditional urine tests. These hair tests are favored by entities with strict anti-drug policies, offering the distinct advantage of a longer detection timeline, up to 90 days, and are collected under direct supervision, making them almost impossible to counterfeit. Nevertheless, for recent drug use within a five-day window, urine tests retain their accuracy.

Hair analysis has emerged as a robust method for detecting drug and alcohol use. Hair offers a comprehensive history of alcohol and other substances by embedding biomarkers in the strands of the growing hair. When taken near the scalp, hair can reveal a detection window of up to approximately three months for alcohol and other substances. Hair is straightforward to collect, moderately hard to tamper with, and convenient to transport.
A sample of 1.5 inches comprising around 200 strands of hair (similar to the thickness of a #2 pencil) close to the scalp will produce 100mg of hair, which is the optimal sample for both screening and verification. For EtG, additional tests, and/or panels above 10, a sample size of 150mg is suggested. It is advisable to weigh the sample using a jeweler's scale. If scalp hair is not present, an equivalent amount of body hair may be gathered. When mentioning head hair, we are specifically referring to scalp hair. Body hair encompasses all other forms of hair (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase where a sample is entered into a lab’s system. This step includes verifying that the sample was properly sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional data entry not covered by an electronic chain of custody.
Screening performs a preliminary check for substance abuse. While it offers a cost-effective method for ruling out drug use on most samples, a positive screen must be confirmed to hold up in legal proceedings. Any samples that are initially positive in Screening require secondary confirmation.
If a sample is initially positive during Screening, additional hair is extracted from the original sample and processed for Extraction. During this phase, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug testing the most challenging methodology.
Confirmation of any positive screen is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All initially positive samples undergo washing before confirmation if necessary. The full laboratory process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Despite being commonly referred to as "hair follicle tests", the test actually examines the hair strand instead of the hair 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.
