Accredited Drug Testing provides extensive hair follicle drug evaluations in Georgetown, California. If you require a drug or alcohol hair test, Accredited Drug Testing is proficient in hair analysis and has facilities Nationwide capable of performing such tests. Generally, having 1.5 to 2 inches of hair on the scalp or body is necessary. Hair analyses can detect drugs, alcohol/ETG, or other specialized testing options.
Recently, hair follicle drug testing has become a preferred method for drug screening. Numerous employers, courts, and substance abuse professionals are opting for hair drug tests over traditional urine tests. Hair follicle drug tests are adopted by organizations with strict drug policies, judicial systems, and individuals on probation. The main advantage is the extended detection window for drug use, typically up to 90 days, through a supervised collection process that is nearly foolproof. Yet, for detecting drug use within the last 5 days, urine tests still provide the most accurate results.

Hair analysis has emerged as an effective means for identifying alcohol and drug consumption. Hair captures a comprehensive timeline of alcohol and drug usage by securing biomarkers within the strands as they grow. If collected near the head, hair offers a detection timeframe of up to 3 months for identifying alcohol and drugs. Collecting hair is straightforward, hard to tamper with, and straightforward to transport.
A sample approximately 1.5 inches long, consisting of about 200 hair strands (similar in size to a #2 pencil) nearest to the head, will yield 100mg of hair, which is the perfect amount for testing and validation. For EtG, additional elements, and tests exceeding 10 panels, 150mg of the sample is advised. Using a jeweler’s scale for weighing the specimen is suggested. Should scalp hair be inaccessible, an equivalent volume of body hair can be used. When mentioning head hair, we refer only to scalp hair. In contrast, body hair includes all other types (facial, underarm, etc.).
Process Overview
The key steps involved in the laboratory analysis of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning covers the initial input of a sample into a lab system. This encompasses ensuring that the sample was properly sealed and transported, generating a random LAN (Laboratory Accessioning Number), and completing any remaining data input not provided by an electronic documentation system.
Screening involves a preliminary assessment for substance abuse. Though cost-efficient for excluding drug usage in most samples, a positive outcome in Screening necessitates verification to be legally valid. Any samples showing potential positive results during Screening require additional confirmation.
Should a sample show a potential positive result during Screening, a larger hair portion is extracted from the original sample and readied for Extraction. In Extraction, drugs are removed from hair at considerably lower levels compared to other methods (e.g., urine or saliva), which explains why hair drug analysis is one of the most challenging methods to execute.
Confirmation of any positive outcome in Screening is performed using GC/MS, GC/MS/MS or LC/MS/MS. Before confirmation, all likely positive samples are cleansed if required. The entire processing from Accessioning to Confirmation is examined per both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Commonly mistaken as "hair follicle tests", the procedure examines the hair strand itself, excluding the follicle under the skin.

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.
