Accredited Drug Testing offers comprehensive hair follicle drug testing services in San Juan, Texas. If you're in need of a hair drug or alcohol test, Accredited Drug Testing focuses on hair testing, with centers nationwide that can conduct hair tests. Typically, 1.5 to 2 inches of hair on the crown or body is required. Tests can assess drugs, alcohol/ETG, or other custom options.
Recently, drug testing methods have shifted towards hair follicle drug tests. This type of testing is increasingly requested by employers, courts, and Substance Abuse professionals over standard urine tests. Hair follicle tests are favored by employers with strict drug-free policies, as well as in judicial settings and probation cases due to their extended detection window, which can span up to 90 days, and because they're nearly impossible to tamper with. However, for detecting recent use within five days, urine tests remain the most reliable.

Utilizing hair testing has gained recognition as a potent method for identifying drug and alcohol use. Hair offers a prolonged account of alcohol and other drugs by capturing biomarkers within the strands of hair as it grows. When collected near the scalp, hair may deliver an approximate 3-month detection duration for alcohol and other drugs. Hair is straightforward to gather, challenging to tamper with, and convenient to transport.
A 1.5-inch section consisting of roughly 200 hair strands (comparable in size to a #2 pencil) nearest to the scalp will yield 100mg of hair, which is optimal for analysis and confirmation. For tests such as EtG, add-ons, and those exceeding 10 panels, a 150mg sample is advisable. It is suggested to measure the specimen using a jeweler’s scale. If scalp hair isn't accessible, an equivalent quantity of body hair can be utilized. When mentioning head hair, we imply scalp hair exclusively. Body hair encompasses all other hair varieties (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a sample into a laboratory’s framework. This step encompasses confirming that the sample was properly sealed and shipped, assigning an arbitrary LAN (Laboratory Accessioning Number), and fulfilling any supplementary data entry absent from an electronic chain of custody system.
Screening comprises an initial rapid assessment for drug abuse. Although Screening is an economical approach to exclude drug usage in most samples, a positive screen requires confirmation for legal acceptance. Any samples presumed positive in Screening necessitate further verification.
If a sample is assumed positive in the Screening phase, additional hair is extracted from the initial specimen and processed for Extraction. During this phase, drugs are retrieved from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), establishing hair drug screening as one of the most challenging practices to execute.
Verification of any positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive undergo washing before confirmation as necessary. The complete laboratory process from Accessioning to Confirmation receives oversight under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 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.
