Accredited Drug Testing provides comprehensive hair follicle testing services in Guasti, California. For those requiring a hair drug or alcohol assessment, our company excels in this area with locations across the nation ready to conduct such tests. Typically, 1.5 to 2 inches of crown or body hair is necessary. These tests detect drugs, alcohol/ETG, or other tailored options through hair analysis.
Recently, hair follicle testing has become a more common method for drug screening. Many workplaces, courts, and substance abuse specialists now prefer hair drug tests over the standard urine test. Companies with zero-tolerance drug policies, legal institutions, and probation cases choose this method. Its primary advantage is the extended detection period of up to 90 days, with observed collection, making it hard to tamper with. However, urine tests remain the most precise for identifying recent drug use (within five days).

Hair testing is regarded as an effective method for identifying drug and alcohol use. Hair captures a prolonged history of alcohol and other drugs by embedding biomarkers within the strands of hair as they grow. When taken from near the scalp, hair can indicate drug and alcohol use over a period of up to around three months. The collection process for hair is straightforward, hard to tamper with, and convenient to transport.
A sampled length of 1.5 inches of approximately 200 hair strands (comparable to a #2 pencil in size) taken nearest the scalp yields 100mg, which is the optimal sample size for both screening and follow-up testing. For EtG, additional tests, and/or tests beyond 10 panels, a specimen weight of 150mg is recommended. It is advisable to use a jeweler’s scale to weigh the specimen. If scalp hair is inaccessible, an equivalent quantity of body hair can be procured. 'Head hair' specifically refers to scalp hair alone. 'Body hair' encompasses all other types, including facial and axillary hair.
Process Overview
The procedural stages in the lab processing of a drug test result consist of Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves initially entering a sample into a laboratory’s system. This step includes checking the sample for proper sealing and shipment, assigning it a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not covered by an electronic chain of custody system.
Screening entails a prompt preliminary check for drug abuse. Screening serves as a cost-effective strategy to eliminate drug use in most samples. However, if the screen is positive, it must be confirmed to be legally valid. Any samples showing a presumptive positive in Screening require a subsequent confirmation.
Where a sample shows a presumptive positive during the Screening phase, additional hair is extracted from the initial specimen and prepared for Extraction. Here, drugs are extracted from hair at a much lower concentration than with other techniques (e.g., urine or oral fluid), which is why hair drug screening stands as the most challenging methodology to conduct.
Confirmation of any positive result is carried out by means of GC/MS, GC/MS/MS, or LC/MS/MS. Every presumptive positive sample undergoes washing before confirmation if necessary. The entire lab process, from Accessioning to Confirmation, adheres to both the CAP (College of American Pathologists) Hair designation and accreditation per ISO/IEC 17025 standards.

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.
