Accredited Drug Testing offers thorough hair follicle drug testing services in Sierra, California. Whether you require a hair drug or alcohol test, Accredited Drug Testing is your expert, with testing facilities in all major cities across the country that can conduct hair tests. Typically, 1.5 to 2 inches of hair from the head or body can be tested. Hair analysis includes drugs, alcohol/ETG, or other personalized testing options.
Recently, hair follicle drug testing is increasingly favored for drug testing. It is frequently mandated by employers, courts, and Substance Abuse specialists in place of the typical urine test. Employers with strict no-drug-use policies, courts, and those on probation often prefer hair drug tests. The key advantage is a longer detection window for drug usage, generally up to 90 days, with an observed collection to prevent tampering. However, for drug use within the past 5 days, urine tests remain the more precise option.

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 testing is now recognized as an effective method for identifying drug and alcohol ingestion. Hair captures a prolonged history of alcohol and other substances by encasing biomarkers within the strands as they grow. When gathered near the scalp, hair offers a detection period of up to roughly 3 months for alcohol and other substances. Hair is straightforward to gather, hard to tamper with, and simple to transport.
A 1.5-inch segment of roughly 200 hair strands (equivalent to a #2 pencil width) nearest to the scalp will yield 100mg of hair, which is the optimal quantity for screening and verification. For EtG, add-ons, or tests exceeding 10 panels, 150mg of the sample is advisable. It's suggested to measure the sample using a jeweler's scale. If scalp hair can't be accessed, a comparable quantity of body hair can be collected. "Head hair" refers exclusively to scalp hair; "body hair" pertains to all other hair types (facial, axillary, etc.).
Process Overview
The testing of a drug sample is comprised of four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning concerns the initial handling of a specimen into a laboratory's database. This step involves confirming that the specimen was appropriately sealed and dispatched, allocating a unique LAN (Laboratory Accessioning Number), and filling in any remaining data entry not included within an electronic chain of custody system.
Screening pertains to an initial rapid evaluation for substances. Although Screening is an economical approach to exclude drug use in most instances, a positive result must be verified for court admissibility. Any specimens that appear positive in Screening necessitate subsequent confirmation.
If a specimen is tentatively positive during Screening, additional hair is chosen from the original sample and readied for Extraction. This phase involves extracting drugs from hair at far lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug testing the most challenging method to execute.
Verification of any positively screened outcome is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumed positive specimens are cleaned before confirmation if necessary. The entire lab process from Accessioning to Confirmation is evaluated following both the CAP (College of American Pathologists) Hair classification and the credentials to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Often named "hair follicle tests", the test itself examines 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. 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.
