Accredited Drug Testing provides comprehensive hair follicle drug testing services throughout Southeast Harris, Texas. For those needing a hair drug or alcohol test, our specialized centers nationwide, including all cities, offer reliable hair testing. Typically, 1.5 to 2 inches of hair from the scalp or body can be used. These tests can screen for a range of substances, including drugs and alcohol/ETG.
Recently, there has been a shift towards hair follicle drug tests for substance detection. Employers, judicial systems, and Substance Abuse professionals are increasingly opting for hair tests over urine tests. Hair follicle testing is favored by organizations enforcing strict no-drug policies due to its extended detection window, often up to 90 days. However, urine tests remain reliable for recent drug use, as they are more accurate when detecting substances used in the past five days.

Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair captures long-term evidence of alcohol and drugs by embedding biomarkers within the fibers of the maturing hair strand. When harvested near the scalp, hair can reveal a detection window for alcohol and substances extending up to roughly three months. Hair collection is straightforward, difficult to tamper with, and convenient for transportation.
A 1.5-inch segment of around 200 hair strands (comparable to the size of a #2 pencil) from the scalp will yield 100mg of hair, which is optimal for both screening and confirmation. For EtG, additional tests, and/or more than 10 panel tests, 150mg of the sample is suggested. We advise weighing the sample with a jeweler’s scale. If scalp hair is absent, an equivalent quantity of body hair can be gathered. By head hair, we specifically mean scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial integration of a sample into a laboratory’s system. This process includes confirming that the sample was correctly sealed and sent, allocating a random LAN (Laboratory Accessioning Number), and completing any remaining data entry not covered by an electronic chain of custody system.
Screening entails a fast preliminary check for substances of misuse. While Screening is an economical approach to eliminate drug usage in most samples, any positive screen result necessitates confirmation for legal acceptability. Samples preliminarily positive in Screening need a subsequent verification.
Should a specimen test presumptively positive during the Screening phase, additional hair is extracted from the initial sample and readied for Extraction. Here, drugs are isolated from hair at a considerably lower concentration than other techniques (such as urine or oral fluid), making hair drug screening the most challenging method to execute.
Positive Screening results undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive specimens are cleansed before Confirmation as necessary. The comprehensive laboratory process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.
Advantages of hair drug testing:
Limitations:
Note: Commonly termed as "hair follicle tests", the analysis is conducted on the hair strand and not 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.
