Accredited Drug Testing offers comprehensive hair follicle drug screenings in Weldon, California. If you're in need of a hair-based drug or alcohol test, our specialty lies in hair testing. We boast testing facilities across all cities nationwide capable of administering hair tests. Generally, 1.5 to 2 inches of hair from your head or body is needed. These tests can analyze substances like drugs and alcohol, and offer tailored testing options.
In recent times, hair follicle drug testing has gained prominence for drug screenings. These tests are increasingly demanded by employers, legal systems, and substance abuse experts in place of traditional urine analyses. Employers enforcing strict no-drug policies, judicial bodies, and probation officials utilize these tests. The key advantage is its extensive detection window, reaching up to 90 days, conducted under supervision, making evasion nearly impossible. For detecting recent drug use within five days, urine tests are still considered most precise.

Hair analysis is now recognized as an effective means for identifying drug and alcohol consumption. Hair strands capture biomarkers during growth, offering an extended timeline of alcohol and drug usage. By obtaining samples near the scalp, hair testing can yield a detection span of up to three months for alcohol and drugs. Hair collection is straightforward, hard to tamper with, and simple to send.
Collecting a 1.5-inch segment comprising roughly 200 hairs (comparable to a #2 pencil) nearest the scalp provides 100mg of hair, which is optimal for both screening and confirmation. For EtG tests, supplemental tests, and/or evaluations exceeding 10 panels, it is advised to collect 150mg. We suggest using a jeweler’s scale for accuracy. If scalp hair is not an option, equivalent body hair can be utilized. When mentioning head hair, we refer specifically to scalp hair. Body hair denotes other types (facial, axillary, etc.).
Process Overview
The laboratory analysis of a drug test result involves four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary integration of a sample into the laboratory’s system, ensuring it was securely sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any outstanding data entry absent from an electronic chain of custody system.
Screening conducts a cursory assessment for drugs. Although Screening serves as a cost-efficient approach for excluding drug use across most samples, a positive screening outcome mandates confirmation for legal acceptability. Samples testing presumptively positive require further confirmation.
In instances of a presumptive positive result during Screening, additional hair is retrieved from the primary specimen for Extraction. This phase involves isolating drugs from hair at significantly lower concentrations than found in other methods (e.g., urine or saliva), portraying hair drug testing as the most intricate approach.
Confirming any positive screening outcomes occurs through GC/MS, GC/MS/MS, or LC/MS/MS procedures. All samples with presumptive positives undergo washing before confirmation as necessary. The complete lab process from Accessioning through to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair classification and adherence to ISO / IEC 17025 criteria.

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. As we embrace these advancements, we pave the way for a safer, healthier society, where drug testing and analysis serve as powerful tools in protecting public health and maintaining integrity in various sectors. The research presented in this special issue will undoubtedly shape the future of drug testing and analysis, fostering collaboration and inspiring further innovation in this crucial area of scientific inquiry.
