Accredited Drug Testing provides comprehensive hair follicle drug testing services in Alpine, Texas. If you're seeking a hair drug or alcohol test, Accredited Drug Testing is a specialist in hair testing, with facilities available nationwide, including every city. Typically, 1.5 to 2 inches of hair is required, though body hair might be used alternatively. Tests can examine drugs, alcohol/ETG, or be customized for other needs.
Increasingly, drug testing has incorporated hair follicle tests in recent years. Many workplaces, judicial systems, and substance abuse experts now demand hair testing over traditional urine tests. Hair analysis is preferred by employers with strict drug-free policies, courts, and probation officers, due to its extensive detection period of up to 90 days. This test is conducted with a supervised collection, making deception nearly impossible. However, for detecting recent usage within 5 days, urine tests remain most effective.

When you're searching for hair drug testing near me or hair drug testing locations, we provide a simple and convenient process to find a drug and alcohol testing location near you that is certified to provide all of your drug and alcohol testing needs.
Hair testing is now regarded as a potent instrument for identifying drug and alcohol intake. By capturing biomarkers within the hair fiber, hair presents a long-term record of alcohol and drug use. When taken from near the scalp, it offers approximately a 3-month window for detecting alcohol and drug use. Hair collection is straightforward, relatively tamper-resistant, and convenient for transportation.
A 1.5-inch segment of around 200 hairs near the scalp (akin to a #2 pencil dimension) amounts to 100mg — the perfect quantity for screening and verification. For EtG applications, supplementary tests, and analyses over 10 panels, a 150mg sample is advisable. We suggest using a jeweler’s scale for specimen weighing. If head hair isn't available, an equivalent amount of body hair can be used. References to head hair pertain to scalp hair only, whereas body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The procedure for lab processing of drug test outcomes involves four essential stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the primary handling of a specimen into a lab’s database. It involves confirming the sample’s proper sealing and transport, allotting a random LAN (Laboratory Accessioning Number), and filling any additional data not covered by an electronic chain of custody framework.
Screening is a preliminary, rapid evaluation for drugs of abuse. Although Screening is an economical approach to exclude drug use for most specimens, court-admissibility requires positive results to be validated. Specimens with presumptive positives in Screening necessitate a follow-up confirmation.
If a specimen shows a presumptive positive during Screening, additional hair from the initial sample is subjected to Extraction. At this phase, drugs are extracted from hair at significantly lower concentrations than in methods like urine or oral fluid, making hair drug testing one of the most challenging methodologies to execute.
Positive results from Screening undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Necessary presumptive positive specimens receive a wash before Confirmation. The full laboratory process from Accessioning to Confirmation is subject to scrutiny under both the CAP (College of American Pathologists) Hair accreditation and ISO / IEC 17025 standards.

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.
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.

I needed a quick drug test for visitation with my children. I called at 6am they answered and set me up with a place a couple miles from my house to go get the test done, that was on Wednesday, I had the results on Friday afternoon and was able to see my kids on Saturday. Thank you for the help!
