Accredited Drug Testing offers comprehensive hair follicle drug testing services in Pittsburg, Texas. For those requiring hair drug or alcohol testing, Accredited Drug Testing excels in this field with testing centers nationwide capable of conducting hair tests. Typically, 1.5 to 2 inches of hair from the head or body is necessary. Hair tests can identify drugs, alcohol/ETG, or be customized for other hair testing needs.
Recently, drug testing methods have increasingly incorporated hair follicle drug tests over conventional techniques. Many employers, legal bodies, and Substance Abuse experts are opting for hair tests rather than urine testing. Hair follicle tests are favored by zero-tolerance employers, courts, and those on probation. They offer an extended detection period of up to 90 days, are monitored during collection, and are difficult to manipulate. For detecting recent substance use within a 5-day window, urine tests remain the most accurate.

Hair analysis is now recognized as a robust method for identifying substance and alcohol consumption. By embedding biomarkers within the hair shaft during growth, hair offers an extensive historical record of substance usage. When collected near the scalp, hair can reveal a detection period of up to around 90 days for alcohol and various other substances. Hair is straightforward to gather, relatively challenging to tamper with, and simple to transport.
A 1.5-inch segment comprising around 200 hair strands (approximately the width of a #2 pencil) situated closest to the scalp provides 100mg of hair, which is the optimal amount for both screening and confirmation procedures. For EtG, ancillary tests, and/or assessments extending beyond 10 panels, a recommended quantity is 150mg of the sample. It is advisable to assess the specimen using a jeweler’s scale. In the absence of scalp hair, a comparable quantity of body hair can be obtained. When mentioning head hair, we specifically refer to scalp hair only. Body hair encompasses all other forms of hair (facial, axillary, etc.).
Process Overview
The key stages in processing a laboratory drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the preliminary processing of a sample into a laboratory’s system. This encompasses verifying that the sample was adequately sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any additional data recording not facilitated by an electronic chain of custody system.
Screening includes a preliminary rapid test for substance misuse. Although Screening is an economical approach to eliminate drug usage in numerous samples, a positive screening necessitates confirmation to be valid in legal proceedings. Any sample that preliminarily tests positive in Screening necessitates a further confirmation.
Should a sample preliminarily indicate positivity during the Screening phase, additional hair is extracted from the original specimen for the Extraction stage. During this stage, substances are isolated from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluids), underscoring why hair drug screening is among the most challenging procedures to execute.
Confirmation of any positive screening outcomes is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo cleaning prior to confirmation as necessary. The comprehensive laboratory protocol from Accessioning to Confirmation undergoes evaluation under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Although frequently referred to as "hair follicle tests", the analysis actually examines the hair strand rather than the hair follicle beneath the scalp.

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!
