In Modesto, California, Accredited Drug Testing offers complete hair follicle drug testing services. If you require a hair test for drugs or alcohol, our centers specialize in hair testing and are located in cities across the nation. For a precise analysis, 1.5 to 2 inches of hair is necessary, either from the scalp or body. Our hair tests can detect drugs, alcohol/ETG, and other tailored testing options.
Recently, hair follicle drug testing has increasingly become the preferred method for drug screening. Many employers, courts, and Substance Abuse professionals now mandate hair drug tests instead of standard urine tests. These tests are favored by employers with zero-tolerance policies, courts, and those on probation due to their extended detection period of up to 90 days, their observed collection process, and difficulty in tampering. Despite this, urine tests remain most accurate for detecting recent drug use within five days.

Hair analysis has emerged as a robust method for identifying drug and alcohol consumption. It offers a comprehensive record of substance use by capturing biomarkers within the strands of growing hair. When obtained near the scalp, hair samples can reveal a detection period stretching up to roughly three months for alcohol and drugs. Hair is easy to gather, not easily tampered with, and straightforward to transport.
A 1.5-inch segment comprising roughly 200 hair strands (similar in size to a #2 pencil) nearest the scalp yields approximately 100mg, considered optimal for both screening and confirmation. For EtG, additional tests, or panels exceeding 10, a 150mg sample is suggested. We advise using a jeweler’s scale to measure the sample. In cases where scalp hair is not accessible, an equivalent amount of body hair can be sourced. When referring to head hair, we mean scalp hair exclusively. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
There are four pivotal steps in processing a drug test result in the lab: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of integrating a sample into the laboratory's system. This process includes confirming the sample's proper sealing and shipping, allotting a random LAN (Laboratory Accessioning Number), and completing any outstanding data entry that isn't provided by an electronic chain of custody system.
Screening involves an initial rapid assessment for drugs of abuse. Though it is a cost-effective method to eliminate drug use in most samples, any positive screen results must be verified to be acceptable in court. Samples that return a presumptive positive in Screening must undergo a secondary confirmation.
If a sample tests presumptively positive during Screening, additional hair is retrieved from the original sample and prepped for Extraction. During Extraction, drugs are extracted at lower concentrations than in other methods (e.g., urine or oral fluid), making hair drug testing the most challenging methodology.
Confirmation of any positive screen result occurs through techniques like GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleaned prior to confirmation as required. The entire lab procedure from Accessioning to Confirmation is overseen by both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Commonly termed "hair follicle tests", the analysis targets the hair strand itself, 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.

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.
