Accredited Drug Testing offers comprehensive hair follicle drug screening services in West Bexar, Texas. Whether you're in need of a hair-based drug or alcohol test, our expertise in this area is unmatched, with a nationwide network of testing facilities capable of conducting such tests. Typically, a hair length of 1.5 to 2 inches is required, and both scalp and body hair are viable for testing substances including drugs and alcohol/ETG, among other specialized options.
Hair follicle drug testing has become increasingly common in recent times as a preferred method over standard urine tests. It's particularly favored by employers, courts, and substance abuse experts for its ability to provide extended detection of drug use, often encompassing up to a 90-day history. This method is ideal for organizations upholding drug-free policies due to the near-impossible likelihood of evading the test and its supervised collection process. Nevertheless, for identifying drug use within a shorter timeframe, such as the last five days, urine tests remain highly precise.

Hair analysis is now viewed 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 expanding hair strand. When obtained from near the scalp, hair can reveal a detection window of up to around 3 months for alcohol and drug use. Hair is straightforward to collect, not easily tainted, and simple to transport.
A 1.5-inch segment of roughly 200 hair strands (similar in size to a #2 pencil) closest to the scalp provides 100mg, which is the optimal amount for testing and validation. For EtG, additional tests, or tests exceeding 10 panels, 150mg of the sample is advised. We suggest measuring the sample with a jeweler’s scale. If scalp hair is not available, an equivalent quantity of body hair can be used. By "head hair," we specifically mean scalp hair. Body hair encompasses all other hair types (e.g., facial, axillary, etc.).
Process Overview
The key laboratory procedures for processing a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the step of integrating a sample into a laboratory system. This step verifies whether the sample was properly sealed and dispatched, assigns a LAN (Laboratory Accessioning Number), and completes any extra data entry absent from an electronic chain of custody system.
Screening entails a preliminary examination for drugs of abuse. Although Screening is an economical approach to eliminate drug usage in most samples, a positive result must be verified for court acceptance. Samples showing a presumptive positive in Screening need subsequent verification.
If a sample shows a presumptive positive result during Screening, additional hair is extracted from the original sample and readied for Extraction. In this phase, drugs are removed from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), explaining why hair drug screening is among the most complex procedures.
Verification of any positive Screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as needed. The complete laboratory process from Accessioning to Confirmation is evaluated according to both CAP (College of American Pathologists) Hair standards and ISO/IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: Often labeled as "hair follicle tests," the analysis actually focuses on the hair strand rather than 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.
