Accredited Drug Testing offers comprehensive hair follicle drug tests in Colfax, California. For those in need of hair or alcohol testing, we are experts in hair assessments with centers across the country available for testing. Typically, 1.5 to 2 inches of hair from your head or body is required. Hair tests can evaluate for drugs, alcohol/ETG, or be tailored for specific purposes.
In recent times, hair follicle drug tests have become a more prevalent means of conducting drug testing. Many institutions, including employers, judicial systems, and substance abuse experts, now prefer a hair drug test over the traditional urine sample. Employers with strict no-drug policies, the courts, and those on probation utilize these tests for their main advantage: a detection period lasting up to 90 days. Collection is supervised, reducing the chance of deception. However, for recent drug use (within the last 5 days), urine tests remain most reliable.

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 increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair captures a long-term account of substances, encapsulating markers within the hair's developing fibers. Samples acquired near the scalp can present a detection period extending up to around three months for alcohol and other substances. Hair is straightforward to gather, relatively tough to tamper with, and simple to transport.
A sample measuring 1.5 inches, consisting of roughly 200 hair strands (similar to a #2 pencil) nearest to the scalp, yields 100mg of hair, which is the optimal amount for both screening and confirmation. For EtG, additional substances, and/or tests exceeding 10 panels, it is advised to use 150mg of the sample. Utilizing a jeweler's scale for weighing the specimen is suggested. Should scalp hair be unavailable, a comparable quantity of body hair can be collected. In the context of head hair, this exclusively pertains to scalp hair. Body hair encompasses all other hair types (such as facial hair, axillary hair, etc.).
Process Overview
The laboratory processing of a drug test outcome involves four principal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary incorporation of a sample into a lab's system. This process includes checking that the sample was correctly sealed and shipped, attributing a random LAN (Laboratory Accessioning Number), and completing any necessary data entry absent in an electronic chain of custody system.
Screening acts as an initial rapid assessment for drugs of misuse. Although Screening provides a cost-efficient means of eliminating drug usage in a majority of samples, a positive screen must be confirmed for it to hold in court. Samples suspected to be positive in Screening mandate a secondary confirmation.
If a sample indicates presumptive positivity during the Screening phase, additional specimen hair is extracted and readied for Extraction. At this stage, drugs are withdrawn from hair at significantly lower concentrations than with other methods (e.g., urine or oral fluid), which makes hair drug screening the most challenging procedure to perform.
Verification of any positive screening outcome is done through GC/MS, GC/MS/MS, or LC/MS/MS. All specimens with presumptive positive outcomes are cleansed before confirmation, if necessary. The complete lab procedure from Accessioning to Confirmation undergoes assessment under the College of American Pathologists (CAP) Hair guidelines and in compliance with the ISO / IEC 17025 standards.

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.
