In Novato, California, Accredited Drug Testing offers a full array of hair follicle drug testing services. Whether you require a hair drug or alcohol test, our specialization lies in hair testing. We have established testing facilities across all cities in the US that can conduct these tests. Typically, 1.5 to 2 inches of hair from your head or body is required. Our hair tests are capable of analyzing drugs, alcohol/ETG, or offering tailored hair testing solutions.
The preference for drug testing procedures has increasingly leaned towards hair follicle drug testing in recent years. This switch is driven by demands from employers, judicial systems, and substance abuse experts who favor hair tests over traditional urine tests. Companies with zero-tolerance drug policies, courts, and probation services often mandate hair follicle tests. One significant advantage of hair testing is its extended detection span, generally covering up to 90 days, coupled with an observed collection process that makes cheating nearly impossible. Despite this, urine tests retain their accuracy for detecting recent drug use within the preceding five days.

Hair analysis is regarded as a robust method for identifying drug and alcohol consumption. Hair captures a chronological record of substances by embedding biomarkers within the strands as they grow. When obtained near the scalp, hair can offer a detection period extending up to three months for alcohol and drugs. Hair is easy to gather, difficult to tamper with, and convenient to mail.
A 1.5-inch segment comprising roughly 200 hair strands (approximately equivalent to the diameter of a #2 pencil) nearest the scalp yields 100mg of hair, which is the ideal quantity for both initial screening and confirmation. For EtG, additional tests, or those surpassing 10 panels, a specimen of 150mg is advisable. We suggest weighing the sample with a jeweler’s scale. If scalp hair is absent, an equivalent quantity of body hair can be obtained. When discussing head hair, it refers exclusively to scalp hair. Body hair encompasses other types (facial, underarm, etc.).
Procedure Overview
The primary components of laboratory processing for drug test results include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a sample into a laboratory's system. This entails verifying proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data recording not provided by an electronic chain of custody system.
Screening offers a preliminary examination for drugs. Although Screening is an economical method to exclude drug usage in the majority of samples, a confirmed positive screen is necessary for legal validity. Samples that result presumptively positive in Screening require secondary confirmation.
If the Screening process suggests a positive result, additional hair from the initial sample is prepared for Extraction. In this phase, drugs are isolated from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), which is why hair drug testing is more challenging to conduct.
Confirmation of any positive screen result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed as necessary prior to confirmation. The complete laboratory procedure from Accessioning to Confirmation is overseen under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

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.
