Accredited Drug Testing provides comprehensive hair follicle drug assessments in Princeton, CA. Whether a hair or alcohol test is needed, we specialize in such services with centers in every city across the nation. For accuracy, a minimum hair length of 1.5 to 2 inches on the head or elsewhere is often required. Tests can evaluate for drugs, alcohol/ETG, and other tailored options.
Recently, using hair follicle tests for drugs has gained traction. Many employers, judicial systems, and substance abuse experts now prefer these over urine tests. The extended detection window of up to 90 days, collected in monitored environments, and difficulty in tampering make them favorable. Nonetheless, for recent drug usage in the past 5 days, urine tests remain the benchmark of accuracy.

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 analysis is recognized as an effective approach for identifying drug and alcohol consumption. Hair strands act as a record, capturing biomarkers within the fibers as they grow. Hair samples taken near the scalp can offer a detection range of up to about three months for both alcohol and drugs. Collection is straightforward, tampering is relatively challenging, and transportation is uncomplicated.
A 1.5-inch segment comprising roughly 200 hairs (approximately the thickness of a #2 pencil) nearest to the scalp yields 100mg, which is the optimal quantity for both initial tests and confirmations. For tests such as EtG, add-ons, or those exceeding 10 panels, 150mg of the sample is advised. It's suggested to weigh the sample using a jeweler’s scale. If scalp hair is not available, a comparable amount of body hair can be gathered. In discussions regarding head hair, we mean scalp hair specifically. Body hair includes all other hair types (facial, axillary, etc.).
Process Overview
The laboratory workflow in processing a drug test involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial phase of incorporating a sample into a lab's system. This stage ensures the sample’s seal and shipment are intact, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data input absent in an electronic chain of custody system.
Screening provides a preliminary assessment for potential drug presence. Although Screening is a cost-effective method to exclude drug use in most samples, any positive findings necessitate confirmation for legal admissibility. Samples testing preliminary positive in Screening require a further confirmation step.
Upon a presumptive positive result during Screening, additional hair is extracted from the original sample and prepared for Extraction. During this phase, drugs are isolated from hair at a much lower concentration compared to other methods (e.g., urine or saliva), making hair drug screening quite challenging.
Confirmation of positive screening results is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as necessary. The complete lab process, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: Commonly termed as "hair follicle tests", this test actually examines the hair strand rather than the hair follicle beneath the scalp.

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.
