Accredited Drug Testing provides comprehensive hair follicle drug exams in Arcata, California. For those requiring a hair drug or alcohol test, our expertise is in hair testing, with centers nationwide. Typically, 1.5 to 2 inches of hair from the head or body suffices. Hair samples can be examined for drugs, alcohol/ETG, or other tailored testing choices.
Hair follicle drug tests have become increasingly common in recent years. Employers, legal systems, and Substance Abuse experts are opting for hair testing instead of urine. These tests are favored where zero-tolerance policies apply, by courts, and for probationary checks. A key advantage is its extended detection time, spanning up to 90 days, with supervised sample collection that's virtually tamper-proof. However, urine tests remain the most precise for recent drug use within 5 days.

Hair analysis is now regarded as an effective means for identifying drug and alcohol consumption. It offers a prolonged history of substance use by capturing biomarkers within the hair's fibers as it grows. By gathering hair near the scalp, a potential detection window of up to three months for alcohol and various drugs is created. Hair collection is straightforward, challenging to tamper with, and easy to transport.
A 1.5-inch section of about 200 hair strands (equivalent to the diameter of a #2 pencil) nearest to the scalp can yield 100mg, which is the optimal amount for testing and confirmation. For EtG, additional tests, or analyses requiring over 10 panels, 150mg is advised. We suggest using a jeweler’s scale for measuring the sample weight. If head hair is inaccessible, a comparable amount of body hair can be used. The term "head hair" specifically refers to hair from the scalp, whereas "body hair" encompasses all other hair forms (facial, axillary, and so on).
Process Overview
Four primary phases are involved in the lab processing of a drug test: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial set-up of a sample into a laboratory's database. This step verifies the sample was correctly sealed and sent, assigns it a random Laboratory Accessioning Number (LAN), and finalizes any extra data input absent from an electronic chain of custody system.
Screening acts as a preliminary drug abuse check. Despite being a budget-friendly strategy to eliminate drug use in most samples, any positive results from Screening must be corroborated for courtroom validity. Samples that test positive in Screening undergo further confirmation.
Should a presumptive positive arise during Screening, additional hair is drawn from the original sample for Extraction. Here, substances are isolated from hair at a concentration notably lower than that used in other methods (e.g., urine tests or saliva testing), making hair drug analysis the most complex method to execute.
Confirmation of any positive finding occurs via GC/MS, GC/MS/MS, or LC/MS/MS. Each presumptive positive sample is cleansed prior to confirmation if necessary. The entire lab sequence, from Accessioning through Confirmation, is evaluated under the College of American Pathologists Hair criteria and ISO / IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: Despite often being called "hair follicle tests," the assessment examines the hair strand rather than the follicle beneath the scalp.
Compared to conventional urine tests, hair follicle testing in Arcata stands out for its superior detection capabilities. Unlike urine tests, which have a limited detection window, hair tests capture a broader history of substance use, resulting in enhanced accuracy.
Hair testing's reliability surpasses traditional methods, making it a preferred option for thorough examination. It reduces the risk of false negatives, ensuring complete and accurate detection of drug use.
Hair follicle testing in Arcata boasts an extended detection period, capturing drug use over up to 90 days. This comprehensive view provides employers with a detailed understanding of an individual’s substance history, beyond the scope of standard tests.
Employers gain significant insights into long-term drug habits, ensuring informed decisions. This extended window is invaluable for detecting substance patterns over months rather than days.
In Arcata, hair follicle testing provides a tamper-resistant solution, minimizing the risk of sample adulteration. These tests are challenging to manipulate, offering a high level of reliability and unquestionable results, essential in maintaining testing integrity.
The process greatly reduces the chance of testing interference, ensuring droplet samples are legitimate. This tamper-resistant nature builds trust and delivers dependable results.

The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.
It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.
Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. 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.
In conclusion, the special issue of Drug Testing and Analysis, featuring manuscripts from the SoHT–GTFI meeting in Verona 2022, reflects the remarkable advancements achieved in this field. The manuscripts provide valuable insights into novel analytical techniques, biomarkers, pharmacokinetics, forensic applications, and ethical considerations.
