Accredited Drug Testing offers comprehensive hair follicle drug testing in Weston Lakes, Texas. If a hair drug or alcohol test is required, Accredited Drug Testing specializes in hair testing, with testing centers available in every city nationwide to conduct a hair test. To use hair, you must have 1.5 to 2 inches of hair on the crown or body in most cases. Hair samples can be examined for drugs, alcohol/ETG, or other specialized testing options.
In recent years, the methods for drug testing often include hair follicle drug tests. Many employers, courts, and Substance Abuse professionals opt for hair drug tests over traditional urine tests. These tests are favored by employers with zero-tolerance policies for drug use, courts, and individuals on probation, as they offer an extended detection window of up to 90 days. The tests are gathered under observation and are difficult to falsify. However, urine tests remain the best choice for detecting drug use within the last 5 days.

In recent years, hair analysis has become an effective method for identifying the usage of drugs and alcohol. Hair strands capture and preserve biomarkers as they grow, offering an extended timeline of substance intake. When obtained near the scalp, hair can indicate drug or alcohol consumption for up to roughly 90 days. Collecting hair is straightforward, hard to tamper with, and convenient for transportation.
A 1.5-inch section containing approximately 200 hair strands (similar in size to a #2 pencil) near the scalp yields 100mg of hair, which is optimal for both screening and confirmation procedures. For tests focusing on EtG, add-ons, or those exceeding 10 panels, 150mg is advised. It is best to weigh the hair using a jeweler’s scale. Should scalp hair be unavailable, an equivalent portion of body hair can be gathered. When mentioning head hair, we specifically refer to scalp hair. Body hair encompasses all other types, including facial and axillary hair.
Process Overview
The laboratory evaluation of a drug test result involves four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage where a sample is logged into a laboratory's tracking system. This step includes confirming that the sample was securely sealed and properly shipped, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any data entry missing from an electronic custody chain.
Screening is a preliminary assessment to detect potential drug abuse. Although screening offers a cost-efficient method to discount drug use in most specimens, any positive screen must be verified to be valid in legal contexts. Samples that yield a presumptive positive result during screening require further confirmation.
In cases where a sample tests presumptively positive at the Screening stage, additional hair from the original sample is used for Extraction. During Extraction, drugs are isolated from hair at much lower concentrations compared to other testing techniques (like urine or oral fluid), making hair drug evaluation notably challenging to execute.
Confirmation of any screening positives is carried out using GC/MS, GC/MS/MS, or LC/MS/MS procedures. Before Confirmation, all presumptive positive samples are cleansed as necessitated. The comprehensive lab process, from Accessioning to Confirmation, is rigorously reviewed following both the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

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.
