Accredited Drug Testing offers thorough hair follicle drug tests in Ravendale, California. Whether you need a test for drugs or alcohol, our expertise lies in hair testing, and our centers are located across all cities in the nation, ready to conduct a hair test. Required hair length is 1.5 to 2 inches on the crown or body hair may suffice. Tests can screen for drugs, alcohol/ETG, or other tailored options.
Hair follicle drug tests have increasingly become a part of drug testing methods in recent years. Employers, courts, and Substance Abuse professionals often choose this over the urine test. Such tests are favored by those with strict drug policies, legal systems, and for probationary monitoring. The key advantage is a broader detection window—up to 90 days—gathered under observation, thus hard to falsify, although urine tests remain most accurate for detecting recent use within 5 days.

Hair analysis has garnered a reputation as a highly effective tool for identifying drug and alcohol consumption. Hair offers an extended historical perspective on alcohol and drug use by embedding biomarkers within the strands of emerging hair. When procured near the root, hair can offer a detection duration of up to roughly three months for alcohol and drugs. The collection of hair is straightforward, relatively difficult to tamper with, and convenient to transport.
A sample measuring 1.5 inches in length with around 200 hair strands (resembling the thickness of a #2 pencil) closest to the scalp yields 100mg of hair, which is the optimal amount for testing and verification. For EtG, additional tests, and/or analyses exceeding 10 panels, 150mg of the sample is advisable. Utilizing a jeweler’s scale for specimen measurement is recommended. If scalp hair is absent, a comparable amount of body hair can be gathered. When referencing head hair, it specifically pertains to scalp hair. Body hair encompasses all other varieties (face, underarm, etc.).
Procedure Summary
The principal phases in the lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning covers the preliminary intake of a sample into a lab’s database. This phase ensures the sample was properly sealed and sent, assigns a unique LAN (Laboratory Accessioning Number), and supplements any additional data not entered by an electronic chain of custody system.
Screening pertains to an initial rapid assessment for substance abuse. Screening serves as a cost-effective means to exclude drug use for most samples, yet a positive screen necessitates verification to be admissible in legal actions. Samples deemed presumptively positive in Screening require an additional validation.
When a sample tests presumptively positive during the Screening phase, additional hair is extracted from the original sample and set up for Extraction. In this phase, drugs are separated from hair at a considerably lower concentration compared to other methods (e.g., urine or oral fluid), hence hair drug screening is the most intricate methodology to execute.
Verification of any positive screening outcome is conducted through GC/MS, GC/MS/MS, or LC/MS/MS. Samples with presumptive positives undergo washing prior to confirmation as needed. The complete lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 criteria.
Benefits of hair drug analysis:
Drawbacks:

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.
