Accredited Drug Testing offers comprehensive hair follicle drug tests in Green Valley Lake, California. If a hair drug or alcohol test is what you need, Accredited Drug Testing excels in hair testing with centers available nationwide, ready to conduct hair tests. Typically, you must have 1.5 to 2 inches of hair from the crown or body. Hair tests can assess drugs, alcohol/ETG, or custom testing needs.
Recently, drug testing methods have increasingly included hair follicle drug tests. Many companies, judicial systems, and Substance Abuse experts prefer a hair drug test over the usual urine test. Hair follicle tests are chosen by employers with no drug use policies, courts, and those on probation. The main advantage is hair follicle tests detect drug use over a longer period, up to 90 days, with observation during collection, making cheating nearly impossible. However, for recent drug use within 5 days, urine tests remain the most precise.

Hair analysis has emerged as an effective means for identifying drug and alcohol consumption. Hair strands offer a prolonged record of alcohol and drug intake by capturing biomarkers within their fibers. When taken from near the scalp, hair can reflect up to a 3-month period of alcohol and drug use. It is easy to gather, relatively tamper-resistant, and straightforward to transport.
A sample measuring 1.5 inches with about 200 hair strands (comparable to the size of a #2 pencil) near the scalp yields 100mg of hair, the optimal quantity for both screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, at least 150mg of hair is advisable. The sample should be weighed on a jeweler's scale. If scalp hair is not present, a comparable amount of body hair can be used. When mentioning head hair, it specifically refers to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The core steps in laboratory drug test evaluation include Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of the preliminary integration of a sample into the lab’s database. This process ensures the sample's proper sealing and dispatch, assigns a random LAN (Laboratory Accessioning Number), and completes any necessary data entry not managed by an electronic custody framework.
Screening is a swift preliminary evaluation for substances of abuse. Though economical, a Screening result needs confirmation to hold legal admissibility. Presumptively positive samples in Screening necessitate an additional confirmation phase.
Should a sample test presumptively positive during Screening, further hair is extracted from the initial sample and made ready for Extraction. In this phase, substances are extracted from hair at significantly reduced concentrations compared to other methods (such as urine or oral fluid), making hair drug testing particularly challenging.
Verification of any positive Screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Samples marked as presumptively positive undergo washing as required before Confirmation. The complete laboratory workflow from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair criteria and is accredited to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although commonly called "hair follicle tests," the test actually examines the hair strand, not the 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. 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.
