Accredited Drug Testing provides comprehensive hair drug testing services in Knowles, Oklahoma. Whether you require a drug or alcohol hair test, we're experts in hair testing. With nationwide testing centers in every city, Accredited Drug Testing can conduct a hair test. Typically, 1.5 to 2 inches of hair from the head or body is needed for testing, which can identify drugs, alcohol/ETG, or other specific requirements.
Recently, drug testing methods have increasingly involved hair follicle drug tests. These tests are preferred by many employers, courts, and Substance Abuse professionals over traditional urine tests. Employers with strict no-drug policies, courts, and probation officers turn to hair drug tests. A hair test's significant advantage is its extended drug detection period of up to 90 days. Moreover, it involves an observed collection process, making tampering almost impossible. However, for detecting recent drug use within 5 days, urine tests remain the most precise option.

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 has emerged as an effective instrument for identifying drug and alcohol consumption. By capturing biomarkers within the fibers, hair delivers an extensive retrospective account of alcohol and other drug usage. Collected from near the scalp, hair can offer up to a roughly 3-month timeframe for detection concerning alcohol and substances. Hair is easy to gather, relatively tamper-proof, and simple to transport.
A sample of 1.5 inches consisting of roughly 200 hairs (approximately the width of a #2 pencil) closest to the scalp will provide 100mg of hair, which is the optimal sample for both screening and confirmation. For EtG, extra tests, and/or assessments exceeding 10 panels, a specimen of 150mg is advised. It's suggested to weigh the specimen using a jeweler’s scale. If scalp hair is unavailable, an equivalent amount of body hair can be collected. When mentioning head hair, it refers exclusively to scalp hair. Body hair refers to any other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is about the preliminary incorporation of a sample into a lab’s system. This phase ensures the sample was sealed and shipped correctly, allocates a random LAN (Laboratory Accessioning Number), and finishes any extra data entry not furnished by an electronic chain of custody system.
Screening provides an initial swift assessment for drugs of abuse. Though Screening is a budget-friendly method to exclude drug usage in most samples, a positive screen needs validation for court admissibility. Samples that are presumptively positive during Screening require secondary confirmation.
When a sample is presumptively positive during Screening, more hair is withdrawn from the initial specimen and readied for Extraction. In this process, drugs are isolated from hair at significantly lower concentrations compared to other techniques (e.g., urine or oral fluid), thus making hair drug screening the most challenging method to execute.
Confirmation of any positive screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed before confirmation as necessary. From Accessioning to Confirmation, the whole laboratory procedure is evaluated under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although sometimes termed "hair follicle tests," the analysis is conducted on the hair strand itself, not the follicle beneath the scalp.
Hair follicle testing in Knowles, OK, offers superior detection accuracy compared to traditional urine tests. This method provides a detailed view of substance use, covering a longer period. It effectively identifies both drug and alcohol consumption, offering better insight for informed decisions than conventional urine testing.
One key advantage of hair testing over urine tests is its increased reliability. Hair follicle tests are harder to tamper with, which enhances test integrity while also detecting substances consumed over a more extended timeframe.
In Knowles, OK, hair follicle testing offers an extended detection window, evaluating substance use over a lengthy period of up to 90 days. This duration provides a comprehensive understanding of an individual’s substance history.
This extended window helps employers gauge an applicant or employee's long-term behavior, offering insights beyond more immediate, short-term testing methods. Thus, they make informed decisions based on accurate data.
The tamper-resistant nature of hair follicle testing in Knowles, OK, provides reliable results that are hard to challenge. Unlike urine tests, hair samples resist adulteration, ensuring that tests reflect actual substance use and not manipulated results.

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.
