Accredited Drug Testing provides extensive hair follicle drug testing in Danville, CA. If a hair drug or alcohol test is required, we specialize in hair testing and have centers across all cities nationwide capable of performing these tests. Generally, 1.5 to 2 inches of hair from either the head or body is needed. Hair tests can screen for drugs and alcohol/ETG, or customized hair testing options are available.
Recently, hair follicle drug tests have become a popular method for drug testing. Employers, courts, and Substance Abuse professionals now often prefer hair drug tests over traditional urine tests. Hair follicle drug tests cater to zero-tolerance drug policies, court mandates, and probation requirements. The major advantage is their longer detection window, often up to 90 days, with observed collection minimizing cheating. However, for drug use detected within 5 days, urine tests remain more accurate.

Regarded as an effective method, hair testing is instrumental for identifying substance and alcohol consumption. Hair acts as a long-term record by embedding biomarkers within the fibers of the hair strand as it grows. When cut near the scalp, hair can show evidence of drug and alcohol use for up to three months. Collecting hair samples is straightforward, challenging to tamper with, and easy to transport.
A 1.5-inch length consisting of roughly 200 strands of hair (approximately matching the size of a #2 pencil) from close to the scalp will yield 100mg of hair, which is the perfect quantity for screening and verifying results. For EtG, additional testing, or tests exceeding 10 panels, 150mg of hair is advised. It is beneficial to measure the sample using a jeweler’s scale. In cases where scalp hair isn't available, body hair can be gathered in an equivalent amount. When we mention head hair, we specifically mean scalp hair. Body hair encompasses other types like facial and axillary hair.
Process Overview
The primary stages in laboratory drug test analysis are Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample undergoes initial processing into the laboratory’s database. This step ensures the sample is properly sealed and sent, assigns a random LAN (Laboratory Accessioning Number), and handles any extra data entry not managed through an electronic custody chain system.
Screening features a first rapid assessment for drug abuse presence. Although Screening offers a cost-effective approach to dismiss drug use in most samples, positive outcomes require confirmation for legal validity. Samples with presumptive positives in Screening necessitate follow-up confirmation.
In cases of presumptive positives in the Screening, more hair is extracted from the original sample for the Extraction step. In this phase, drugs are drawn from hair at a more diluted concentration compared to other methods (e.g., urine or oral swabs), making hair drug screening the most challenging technique to execute.
Any screening positive result undergoes confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation, as required. The overall process from Accessioning to Confirmation is conducted with oversight from both the CAP (College of American Pathologists) Hair requirements and the ISO / IEC 17025 standards.

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.
