Accredited Drug Testing offers comprehensive hair follicle drug testing services in Town West, Texas. For hair drug or alcohol testing, Accredited Drug Testing specializes in these services with facilities available nationwide for hair testing. You typically need 1.5 to 2 inches of hair from your head, though body hair may also be used. Hair testing can screen for drugs, alcohol/ETG, or other customized options.
Recently, drug testing often includes the hair follicle method. Employers, courts, and substance abuse professionals prefer this over standard urine tests. Hair follicle exams are ideal for zero-tolerance employers, courts, and probationary individuals due to their long detection period, up to 90 days. They are nearly foolproof to cheat when collected under observation, though for drugs consumed in the last 5 days, urine tests remain more precise.

Hair testing is now regarded as a robust method for identifying the use of drugs and alcohol. Hair acts as a historical record for alcohol and other drugs by incorporating biomarkers within the fibers of the hair as it grows. When harvested near the scalp, hair can offer a detection period of nearly three months for alcohol and drugs. The process of collecting hair is straightforward, relatively tamper-resistant, and convenient for shipping.
A 1.5-inch length of roughly 200 hair strands (equivalent to the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, which serves as the optimal sample for both screening and confirming results. For EtG, additional components, and/or tests exceeding 10 panels, a specimen weighing 150mg is advised. Measuring the specimen on a jeweler’s scale is recommended. In the absence of scalp hair, an equivalent quantity of body hair can be used. "Head hair" specifically refers to scalp hair, while "body hair" encompasses all other hair types (such as facial or axillary hair).
Process Overview
The laboratory processing of a drug test result encompasses four key steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is initially incorporated into the laboratory’s system. This step includes confirming the sample was properly sealed and sent, generating a random LAN (Laboratory Accessioning Number), and finalizing any extra data entry not facilitated by an electronic chain of custody system.
Screening provides an initial scan for substances of abuse. While it serves as a cost-efficient method to eliminate drug use across most samples, a positive screen necessitates confirmation to be legally valid. Samples deemed presumptively positive during Screening require further confirmation.
Should a sample indicate a presumptive positive in the Screening phase, more hair is taken from the original specimen to prepare for Extraction. In this phase, hair yields drugs at a much lower concentration compared to other methods (such as urine or oral fluid), making hair drug screening particularly challenging.
Confirmation of any positive screening results is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive specimens undergo a washing process prior to confirmation as required. The complete laboratory process from Accessioning through Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

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. As we embrace these advancements, we pave the way for a safer, healthier society, where drug testing and analysis serve as powerful tools in protecting public health and maintaining integrity in various sectors. The research presented in this special issue will undoubtedly shape the future of drug testing and analysis, fostering collaboration and inspiring further innovation in this crucial area of scientific inquiry.
