In Grand Terrace, California, Accredited Drug Testing offers comprehensive hair follicle drug testing. Specializing in hair testing for drugs and alcohol, we have centers nationwide capable of performing these tests. Typically, at least 1.5 to 2 inches of hair from the scalp or body is required. These tests can detect drugs, alcohol/ETG, or other custom options.
Recently, hair follicle drug testing has become a more popular method for conducting drug screenings. Employers, court systems, and Substance Abuse professionals increasingly choose hair tests over traditional urine tests. This test is favored by those with zero-tolerance policies for its extended detection period of around 90 days, offering an observed process that is difficult to tamper with. Nonetheless, for recent drug use within the last 5 days, urine tests remain most accurate.

Hair analysis is increasingly esteemed as an effective method for identifying substance and alcohol consumption. Hair offers an extensive timeline of substance markers by capturing them within the hair’s structural fibers. Acquired near the scalp, hair can present an approximate 3-month detection span for alcohol and drugs. Hair is straightforward to procure, challenging to tamper with, and simple to dispatch.
A 1.5-inch hair sample comprising about 200 strands (approximately the girth of a #2 pencil) near the scalp yields 100mg of hair, an optimal amount for testing and validation. For EtG, supplementary, and/or tests exceeding 10 panels, 150mg of the sample is advised. Utilizing a jeweler’s scale to weigh the sample is suggested. Should scalp hair be lacking, an equivalent quantity of body hair is permissible. Reference to head hair pertains exclusively to scalp hair. Body hair encompasses all other hair classifications (facial, axillary, etc.).
Process Overview
The principal procedures entailed in laboratory processing of a drug test include Accessioning, Screening, Extraction, and Confirmation.
Accessioning constitutes the preliminary processing of a sample into a lab’s system. This process ensures the sample was correctly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and completes any supplemental data entry absent in an electronic chain of custody setup.
Screening comprises a preliminary inspection for substances of misuse. While Screening is economical to dismiss drug utilization in a majority of samples, a positive indication needs validation for courtroom acceptance. Samples presumptively positive during Screening necessitate a successive confirmation.
A presumptive positive sample during Screening prompts additional hair extraction from the main sample preparing it for Extraction. Here, drugs are extracted from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), making hair drug testing formidable to conduct.
Confirming any positive screen result occurs via GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples undergo cleansing prior to Confirmation if needed. The entire lab procedure from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair definition 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.
