Accredited Drug Testing provides comprehensive hair follicle drug testing services in Valinda, California. If you're seeking a drug or alcohol analysis, we excel in hair testing and have facilities across the nation capable of conducting these tests. Generally, 1.5 to 2 inches of hair from your head or body is needed. Hair tests can identify drugs, alcohol/ETG, or other custom testing requests.
Recently, the preference for drug testing methods has leaned towards hair follicle tests. Employers, courts, and substance abuse experts now often favor these over traditional urine tests. Such tests are particularly beneficial for organizations enforcing strict no-drug policies, judicial systems, and probation. The main advantage is the extended detection range, up to 90 days, using an observed collection process that's difficult to bypass. Urine tests, however, remain the top choice for detecting recent drug use within 5 days.

Hair analysis is now recognized as an effective method for detecting substance use. By capturing biomarkers in the hair strand's fibers, hair reflects a prolonged record of alcohol and drug exposure. If extracted near the scalp, hair can reveal drug and alcohol presence over an approximate 90-day timeframe. Collection is straightforward, tampering is challenging, and shipping is uncomplicated.
A sample around 1.5 inches long and consisting of roughly 200 strands (about the thickness of a #2 pencil) close to the scalp provides 100mg of hair, which is optimal for both initial testing and confirmation. For EtG, extra checks, and/or tests exceeding 10 panels, a specimen of 150mg is advisable. Using a jeweler’s scale to weigh the sample is suggested. Absent scalp hair, a comparable quantity of body hair may suffice. "Head hair" refers exclusively to scalp hair, while "body hair" encompasses all other hair types (facial, axillary, etc.).
Process Overview
Drug test results undergo four primary lab processing steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is initially processed into the lab's system. This involves checking proper sealing and shipping, allocating a random LAN (Laboratory Accessioning Number), and fulfilling additional data entry that an electronic chain of custody system might lack.
Screening is an initial and swift evaluation for illicit substances. While an economical option to discount drug use in most cases, a positive Screening result must be validated for court eligibility. Any samples with a presumptive positive in Screening require subsequent confirmation.
When presumptive positivity arises during Screening, more hair is sourced from the first specimen for Extraction. Here, drugs are retrieved from hair in lower concentrations than with other techniques (e.g., urine or oral fluid), explaining hair drug screening's complexity.
Positive Screening results undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive specimens are cleansed prior to Confirmation if necessary. The comprehensive lab procedure, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 standards’ 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. 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.
