Accredited Drug Testing offers comprehensive hair follicle drug testing services in Oak Valley, Texas. If you need a hair drug or alcohol test, Accredited Drug Testing is an expert in hair analysis, with testing centers nationwide that can administer a hair test. Generally, you need 1.5 to 2 inches of hair on your head or body for testing. Hair samples can be tested for drugs, alcohol/ETG, or tailored testing options.
Recently, hair follicle drug testing has become a more common method for conducting drug tests. Many employers, courts, and Substance Abuse professionals now prefer hair drug tests to the traditional urine tests. These tests are popular with zero-tolerance employers, courts, and probationers. A major advantage of hair follicle drug tests is their extended detection duration, typically up to 90 days, with observed collection, making them tamper-resistant. However, urine tests are still preferred for detecting very recent drug use within the last 5 days.

Hair testing is now recognized as an effective method for identifying drug and alcohol usage. It provides an extended record of substances by embedding biomarkers within the strands as they grow. When collected near the scalp, hair can reveal drug and alcohol consumption up to approximately three months prior. It is easy to gather, tough to tamper with, and straightforward to transport.
A hair sample measuring 1.5 inches consisting of roughly 200 strands (comparable to the girth of a #2 pencil) near the scalp can weigh 100mg, which is ideal for screenings and confirmations. For EtG, additional analyses, or tests exceeding 10 panels, 150mg is the suggested amount. Using a jeweler’s scale is advisable to weigh the hair. If head hair is inaccessible, equivalent body hair can be utilized. References to head hair pertain solely to hair from the scalp, while body hair encompasses other types (facial, axillary, etc.).
Process Overview
The core steps in lab processing for drug test outcomes are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the procedure whereby a sample is initially processed into a laboratory's system. The actions involve ensuring the sample’s seal and shipment are intact, assigning a random LAN (Laboratory Accessioning Number), and completing any other data entry not included in an electronic chain of custody system.
Screening is a preliminary check for illegal substances. While it efficiently rules out drug use in numerous instances, a positive result requires further confirmation to be legally valid. Samples yielding a presumptive positive in Screening necessitate additional verification.
If a sample shows presumptive positivity during Screening, more hair is extracted from the initial sample for the Extraction phase. Here, drugs are extracted at lower concentrations than with other techniques (e.g., urine or oral fluid), making hair drug analyses particularly rigorous to execute.
Confirmation of positive screenings is executed using GC/MS, GC/MS/MS or LC/MS/MS techniques. Any presumptive positive samples undergo a cleansing process before confirmation as necessary. The lab processing, from Accessioning to Confirmation, adheres to both the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

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.
