Accredited Drug Testing provides comprehensive hair follicle drug testing services throughout Simi Valley, CA. If you're in need of a hair-based drug or alcohol test, our specialty centers offer hair testing nationwide, capable of conducting precise tests in various cities. A minimum of 1.5 to 2 inches of hair from the crown or body is usually required. These assays detect drugs, alcohol/ETG, or can be tailored for specific testing needs.
In recent times, hair follicle tests have become more commonplace in drug screening methods. Employers, legal systems, and substance abuse professionals are increasingly favoring hair tests over traditional urine analyses. These tests are employed by organizations with strict no-drug policies, judicial bodies, and probationary supervision. The key advantage of hair follicle tests is the extended detection window of up to 90 days, using supervised collection and making it nearly foolproof. Yet, for recent drug use (within past 5 days), urine tests remain the most accurate.

When you're searching for hair drug testing near me or hair drug testing locations, we provide a simple and convenient process to find a drug and alcohol testing location near you that is certified to provide all of your drug and alcohol testing needs.
Hair screening is now viewed as an effective means for identifying drug and alcohol usage. Hair retains a prolonged history of substances by embedding biomarkers within the strands as they grow. Hair collected near the scalp can present a detection span of up to 3 months for alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and convenient to send.
A 1.5-inch section consisting of around 200 hair strands (comparable to a #2 pencil thickness) near the scalp will yield 100mg of hair, the perfect sample for both screening and confirmation. For EtG, additional tests, or panels exceeding 10, it’s advisable to use 150mg of the specimen. We advise using a jeweler’s scale for weighing the specimen. In the absence of scalp hair, an equivalent amount of body hair can be used. When we mention head hair, we mean scalp hair specifically. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is about the initial processing of a sample within a laboratory system. This process checks that the sample was appropriately sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data entry that might be missing from an electronic chain of custody system.
Screening provides an initial rapid assessment for the presence of drugs of abuse. While screening offers a cost-efficient method to eliminate drug use in many samples, a positive outcome requires confirmation for legal admissibility. Samples with an initial positive screen need secondary confirmation.
In cases where a sample is positive in the Screening phase, extra hair is taken from the initial sample for Extraction. In this phase, drugs are isolated from the hair at much lower concentrations than other methods (e.g., urine or oral fluid), which makes hair drug screening the most challenging method to perform.
Confirmation of a positive screening result is done using GC/MS, GC/MS/MS, or LC/MS/MS. Any samples indicating a presumptive positive result are washed before confirmation as required. The entire lab process from Accessioning to Confirmation adheres to the CAP (College of American Pathologists) Hair designation and is accredited to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: While commonly termed as "hair follicle tests", the focus is on analyzing the hair strand rather than the follicle beneath the scalp.

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.
