Accredited Drug Testing offers full-service hair follicle drug testing in Belvedere, CA. For those needing a drug or alcohol hair test, our specialized centers provide hair testing across all major cities nationwide with proficiency in conducting hair tests. Generally, 1.5 to 2 inches of hair from the scalp or body can be used. Hair testing can detect drugs, alcohol/ETG, or be tailored for other specific hair analysis.
Nowadays, hair follicle drug testing has become more prevalent in drug screening methods. Employers, legal courts, and substance abuse professionals now frequently opt for hair drug tests over traditional urine tests. Organizations with zero-tolerance policies, legal systems, and probation services rely on hair follicle screenings, which offer a longer detection window of up to 90 days, conducted under supervision to minimize tampering risks. However, for recent usage within 5 days, urine tests remain more effective.

Hair analysis is now regarded as a potent method for identifying drug and alcohol consumption. Hair offers an extended timeline by capturing markers in the strands of growing hair. Collected near the scalp, hair can reveal alcohol and drug presence for up to roughly 3 months. It's straightforward to collect, somewhat resistant to tampering, and easy to transport.
A sample measuring 1.5 inches of roughly 200 hair strands (comparable to a #2 pencil) near the scalp provides 100mg, which is ideal for evaluation and validation. For EtG, additional tests, and/or those exceeding 10 panels, a specimen of 150mg is advised. We advise using a jeweler’s scale for weighing the sample. If scalp hair isn't available, an equivalent amount of body hair can be used. In discussing head hair, we mean scalp hair only, while body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The lab processing of drug test results involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial integration of a sample into a lab's system. This covers confirming the sample's proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing additional data entry not covered by an electronic chain of custody.
Screening offers a preliminary check for drug abuse. Screening is a low-cost method to eliminate drug usage in most samples, but a positive screen requires confirmation for court validity. Samples that test potentially positive in Screening need a further confirmation.
If Screening indicates a presumptive positive, more hair is extracted from the initial sample for Extraction. In this phase, drugs are isolated from hair at a significantly lower concentration than other methods (like urine or oral fluid), making hair drug testing the most challenging method to perform.
Confirmation of positive screening outcomes is performed via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed before confirmation as necessary. The entire lab sequence from Accessioning to Confirmation is verified under both the CAP (College of American Pathologists) Hair designation 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. 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.
