Accredited Drug Testing offers comprehensive hair follicle drug testing services in Davis, Oklahoma. If you've been asked to undergo hair drug or alcohol testing, our expertise lies in hair testing, with centers located nationwide, including all cities. Generally, you'll need 1.5 to 2 inches of hair from the crown or body to conduct the test. These tests can check for drugs, alcohol/ETG, or other specific options.
Recently, hair follicle drug testing has grown more prevalent. Many employers, the judiciary system, and substance abuse counselors are opting for this method over traditional urine tests. Hair follicle testing is favored by employers with strict no-drug policies, legal entities, and probation officers. Its primary advantage is detecting substance use over a longer window—often up to 90 days—with observation during collection, making it nearly tamper-proof. However, for drug use within the last five days, urine tests remain the most accurate.

Recognized as an effective resource, hair testing is utilized for identifying drug and alcohol consumption. This method offers a comprehensive timeline of drug markers preserved within the strands of hair as they grow. When collected from just above the scalp, hair samples can reveal evidence of alcohol and drug use for up to a three-month timeframe. The collection process is straightforward, tampering is more challenging, and shipping is simple.
A sample measuring 1.5 inches from around 200 hair strands (approximately the size of a #2 pencil) situated near the scalp yields 100mg of hair, which is the optimal quantity for both screening and definitive testing. For EtG, supplementary tests, or those exceeding 10 panels, it's advisable to collect 150mg of hair. Using a jeweler’s scale for weighing the sample is recommended. If it's not possible to obtain scalp hair, a comparable amount of body hair may be collected. By 'head hair,' we mean only scalp hair; 'body hair' pertains to other hair types (like facial, axillary, etc.).
Process Overview
The core steps in processing a laboratory drug test result include Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is entered into the laboratory's system. This step entails checking whether the sample was sealed and shipped correctly, assigning it a unique LAN (Laboratory Accessioning Number), and completing any supplementary data tasks not managed electronically by a chain of custody system.
Screening offers an initial assessment for drug presence. This quick-check method is a low-cost approach to eliminate drug use in most samples; however, confirmed positivity is necessary for legal proceedings. All samples indicating potential positivity during Screening require additional confirmation.
In instances where Screening suggests a positive result, further hair is taken from the sample for Extraction. This phase involves extracting drugs at lower concentrations than in other methods (e.g., urine or oral fluid), making hair drug screening the most intricate method.
Confirmation of positive screenings occurs via GC/MS, GC/MS/MS, or LC/MS/MS. Preceding confirmation, samples showing potential positivity undergo thorough washing. The complete lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair category and ISO / IEC 17025 certification.
Advantages of hair drug testing:
Limitations:
Note: Commonly known as "hair follicle tests," these tests assess the hair strand itself, not the follicle beneath the scalp.

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.
