Accredited Drug Testing offers comprehensive hair follicle drug testing services in Signal Hill, California. If you're looking for a reliable hair drug or alcohol test, we specialize in hair testing and have facilities nationwide where a hair test can be performed. Generally, you need between 1.5 to 2 inches of hair on your head or body, as these can be used for various drug and alcohol tests, including customized options.
Lately, conducting drug tests has increasingly involved the use of hair follicle drug tests. Many companies, judicial systems, and substance abuse specialists are opting for hair drug tests instead of traditional urine tests. Employers with zero-tolerance drug policies, courts, and individuals on probation are now using hair follicle tests. The key advantage of this method is its extended detection period for substance use—around 90 days. It involves an observed collection process, making it nearly foolproof. However, for detecting drug use within the past five days, urine tests remain the most precise option.

Hair testing is recognized as a robust method for identifying drug and alcohol use. This method captures a prolonged record of substance intake by embedding biomarkers within the strands of hair as they grow. Testing hair collected near the scalp offers a detection span of up to three months for various substances. Hair collection is straightforward, relatively tamper-resistant, and easily transported.
Obtaining a 1.5-inch segment consisting of roughly 200 hair strands (comparable to the thickness of a #2 pencil) near the scalp yields 100mg of hair, which is optimal for both screening and confirmation stages. For tests that include EtG, add-ons, and those exceeding 10 panels, 150mg of hair is advised. It is best to measure the sample using a jeweler’s scale. If scalp hair can't be acquired, a similar volume of body hair can be used. When discussing head hair, this specifically indicates scalp hair. Body hair encompasses all other types such as facial and axillary hair.
Process Overview
Laboratory processing for drug tests includes the steps of Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of the initial processing and integration of a sample into a lab's systems. This step ensures proper sealing and shipping, assigns a random LAN (Laboratory Accessioning Number), and finalizes any additional data input absent from the electronic chain of custody.
Screening initiates a quick assessment for drug presence. Although economical for ruling out substance use in most samples, any positive results in Screening must undergo confirmation to be court-admissible. Samples showing presumptive positivity necessitate further confirmation.
Samples showing presumptive positivity in the Screening phase undergo Extraction, requiring more hair from the primary specimen. Here, drugs are extracted from hair in much lower concentrations compared to urine or oral fluid methods, making hair testing the most complex method to execute.
For validating any positive screening outcomes, GC/MS, GC/MS/MS, or LC/MS/MS methods are used. Presumptively positive samples receive washing prior to confirmation if needed. The full laboratory sequence, from Accessioning through Confirmation, adheres to both CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Despite frequently being termed "hair follicle tests", the examination focuses on the hair strand rather than the follicle itself.

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.
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.

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.
