Accredited Drug Testing offers comprehensive hair follicle drug testing services in Laureles, Texas. If you're in need of a hair drug or alcohol test, our expertise in hair testing is unmatched. We have testing centers across the nation that can conduct a hair test. Typically, you need 1.5 to 2 inches of hair from the crown or body for most cases. Hair testing can be configured to check for drugs, alcohol/ETG, or other customized options.
Recently, hair follicle drug testing has become a preferred method for detecting drug use. Many employers, judicial systems, and substance abuse professionals are now opting for this method over traditional urine testing. Employers with strict no-drug policies, courts, and those on probation often use hair tests. The advantage of hair follicle tests is their extended detection window—up to 90 days—through an observed collection that is nearly impossible to tamper with. However, for drug use within the past 5 days, urine tests remain the most accurate.

Using hair as a testing medium has become increasingly recognized for its efficacy in identifying drug and alcohol consumption. Hair retains a comprehensive record of substances by capturing biomarkers within the strands as they develop. When the hair is sampled near the scalp, it can offer a detection timeframe of up to nearly three months for various substances. The collection of hair is straightforward, challenging to manipulate, and convenient to transport.
An ideal sample consists of a 1.5-inch section of approximately 200 hair strands (roughly equivalent to the thickness of a #2 pencil) located closest to the scalp, resulting in about 100mg of hair which is optimal for both screening and confirmation processes. For enhanced tests such as EtG, additional panels, or tests exceeding 10 categories, a 150mg sample is advisable. Using a jeweler’s scale to weigh the specimen is recommended. In the absence of scalp hair, a comparable quantity of body hair can be utilized. "Head hair" specifically refers to scalp hair, while "body hair" encompasses all other types, including facial and axillary hair.
Process Overview
The laboratory procedure for processing drug test results comprises four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the step where a sample is initially entered into the laboratory’s workflow. This phase involves confirming that the sample has been appropriately sealed and shipped, assigning it a unique LAN (Laboratory Accessioning Number), and completing any extra data entry not already addressed by an electronic chain of custody system.
Screening entails a preliminary examination for drugs of abuse. While this step is a cost-efficient method to dismiss most drug usage cases, a positively screened result requires confirmation to be legally valid. Any samples classified as presumptively positive during Screening need to undergo additional verification.
When a sample tests as presumptively positive during the Screening phase, additional hair is taken from the original sample and readied for Extraction. In this phase, the concentration of drugs extracted from hair is significantly lower compared to other techniques (e.g., urine or oral fluid), which is why hair drug screening is among the most complex methods to execute.
Confirmation of any positive findings from the Screening process is carried out through methods like GC/MS, GC/MS/MS or LC/MS/MS. Before confirmation, all samples marked as presumptively positive are washed accordingly. The complete laboratory protocol from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the accreditation standards of ISO / IEC 17025.
Advantages of hair drug testing:
Limitations:
Note: Although commonly called "hair follicle tests", the analysis targets the hair strand 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.
