Accredited Drug Testing provides comprehensive hair follicle drug testing services in Alhambra Valley, California. Specializing in hair analysis for drugs and alcohol, our nationwide testing facilities, including those in all cities, can accommodate your testing needs. Typically, a hair length of 1.5 to 2 inches is necessary, though body hair may also be used. Our hair tests can detect drugs, alcohol/ETG, and offer other tailored analysis options.
Recently, the trend in drug testing methods has shifted towards hair follicle analysis. Employers, courts, and substance abuse professionals often prefer hair tests over traditional urine tests. This preference is due to hair follicle testing's longer detection period of up to 90 days, lack of easy cheating, and the observation during sample collection. However, for identifying recent drug use within five days, urine testing remains optimal.

Hair analysis has become recognized as an effective means for detecting substance use. Hair offers a chronicle of alcohol and drugs by encapsulating indicators within the strands’ fibers. Positioned near the scalp, hair can reveal a detection history extending up to three months for various substances. Hair is straightforward to collect, not easily tampered with, and simple to transport.
A 1.5-inch sample consisting of about 200 hair strands (comparable to a #2 pencil's size) near the scalp yields 100mg of hair, which is optimal for evaluation and validation. For EtG, additional tests, and/or those exceeding ten panels, a sample of 150mg is advised. We suggest using a jeweler's scale for weighing the sample. If scalp hair isn't available, a similar quantity of body hair can be gathered. When we reference head hair, we mean only scalp hair. Body hair encompasses all other types such as facial or axillary hair.
Process Overview
The four primary steps in a laboratory’s drug test processing involve Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the primary processing of a test sample into the lab's system. This involves confirming that the sample was appropriately sealed and transported, generating a random LAN (Laboratory Accessioning Number), and completing any data entry not covered by an electronic custody system.
Screening involves an initial swift assessment for substance abuse. While Screening is an economical method to exclude drug usage in most samples, any positive finding requires confirmation for courtroom acceptability. Samples with presumptive positives in the Screening stage necessitate further confirmation.
Should a sample show a presumptive positive during Screening, additional hair from the initial sample is utilized for Extraction. Here, substances are isolated from hair at considerably lower concentrations compared to alternate methods like urine or oral fluid, rendering hair drug screening the most challenging method to execute.
Confirmation of any positive outcome in Screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS technology. Positive samples are cleansed before confirmation as necessary. The comprehensive lab progression from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair guidelines and ISO/IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: While commonly termed as "hair follicle tests", the analysis itself is conducted on the hair strand not 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.
