Accredited Drug Testing offers extensive hair follicle drug tests in Woodbridge, California. For those needing a hair drug or alcohol evaluation, we specialize in hair sampling, with centers across every city nationwide equipped to handle hair tests. Typically, having 1.5 to 2 inches of hair on your head or body is necessary. Hair tests can detect drugs, alcohol/ETG, or other specialized testing options.
Recently, hair follicle drug tests have increasingly been used in drug testing practices. Employers, courts, and Substance Abuse experts often require a hair test over a standard urine analysis. Hair follicle tests are preferred by employers supportive of zero-tolerance drug policies, judicial courts, and those on probation. Their main advantage lies in a longer drug detection window, usually up to 90 days, through an observed process that is almost impossible to deceive. However, urine tests remain the most precise method for detecting drug use within the previous 5 days.

Hair testing is increasingly recognized as an effective means for identifying drug and alcohol use. Hair captures a long-term record of substance consumption by embedding biomarkers within the strands as they grow. When hair is collected near the scalp, it can offer a detection timeline of up to roughly three months for various substances. The process of collecting hair is straightforward, challenging to tamper with, and simple to transport.
A hair segment measuring 1.5 inches with around 200 strands (approximately the girth of a #2 pencil) nearest to the scalp yields 100mg, the volume optimal for both initial screening and verification. For EtG, enhancements, or tests exceeding 10 panels, 150mg is ADVISED. Using a jeweler’s scale is suggested for weighing the sample. Should scalp hair be unobtainable, an equivalent mass of body hair can be used. "Head hair" specifically refers to scalp hair in these contexts, whereas "body hair" encompasses all other varieties such as facial and axillary hair.
Process Overview
The key phases in processing a drug test result in a lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning takes care of the initial sample processing within a lab’s system, making sure the sample is properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and entering any extra data not covered by an electronic chain of custody system.
Screening is about a preliminary fast analysis for substances of abuse. Even though Screening is economical for negating drug use in most cases, a positive result demands confirmation to stand in legal proceedings. Samples that screen positive presumptively require a follow-up confirmation.
Should a sample yield a presumptive positive during Screening, additional hair is taken from the original specimen and readied for Extraction. In this stage, substances are extracted from hair at considerably lower levels than with other methods (e.g., urine or saliva), highlighting the challenge of hair drug screening.
Confirmation of any positive screen involves techniques like GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation if needed. The full laboratory sequence, from Accessioning to Confirmation, is examined under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 benchmarks.
Advantages of hair drug testing:
Limitations:
Note: Although often called "hair follicle tests", the analysis focuses on the hair strand itself and not the follicle beneath the scalp.

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.

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.
