Accredited Drug Testing operates comprehensive hair follicle drug assessments in Patterson, California. For those requiring hair-based drug or alcohol testing, Accredited Drug Testing is a leader, featuring testing facilities nationwide capable of administering a hair-based test. Typically, 1.5 to 2 inches of head or body hair is necessary. These tests can investigate drugs, alcohol/ETG, or be tailored for specific needs.
Recently, hair follicle drug testing has become a more favored approach. Many businesses, judicial systems, and substance abuse experts now prefer a hair drug test to the traditional urine specimen test. Employers with zero-tolerance drug policies, courts, and individuals under probation supervision opt for hair tests. The key advantage is its extended detection window, reaching up to 90 days, utilizing an observed collection process, minimizing tampering opportunities. For apprehending drug use within a 5-day window, urine tests maintain superior accuracy.

Hair testing has emerged as a significant method for identifying drug and alcohol consumption. Hair can encapsulate markers in the strands as they grow, providing a lasting record of alcohol and drug use. When hair is sourced near the scalp, it offers roughly a 3-month timeframe for detecting these substances. Gathering hair is straightforward, it's somewhat resistant to tampering, and easy to transport.
A sample of 1.5 inches, consisting of about 200 hair strands (about the size of a #2 pencil) nearest the scalp, will yield 100mg of hair, which is optimal for screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, a 150mg sample is suggested. It's advisable to weigh the sample with a jeweler’s scale. If scalp hair isn't available, an equal quantity of body hair can be used. When we cite head hair, it refers solely to scalp hair. Body hair denotes all other hair types (facial, axillary, etc.).
Process Overview
The laboratory analysis of a drug test result consists of four principal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step in processing a sample within a lab’s system. This phase includes confirming that the sample was securely sealed and sent, assigning it a random LAN (Laboratory Accessioning Number), and recording any additional information not included by an electronic chain of custody system.
Screening is the stage where a preliminary evaluation for drugs of abuse is conducted. While Screening is an economical means to eliminate most samples from being drug-positive, any positive results require confirmation for legal admissibility. Samples indicating positive in Screening necessitate a further confirmation.
When a sample shows presumptive positivity in the Screening phase, additional hair is extracted from the original sample for the Extraction phase. Here, drugs are removed from hair at a lower concentration compared to other methods (e.g., urine or oral fluid), which makes hair drug screening the most challenging method to execute.
Confirmation for any positive screen result is conducted through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation if necessary. The complete lab process from Accessioning to Confirmation is scrutinized under both CAP (College of American Pathologists) Hair accreditation and ISO / IEC 17025 standards compliance.
Advantages of hair drug testing:
Limitations:
Note: Despite often being termed "hair follicle tests", the test analyzes the hair strand rather than the follicle beneath the scalp.

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.
