Accredited Drug Testing offers thorough hair follicle drug testing services in Lynwood, California. If a hair drug or alcohol test is needed, our expertise lies in hair testing, and we offer testing centers nationwide, including in all cities, to conduct a hair test. Typically, 1.5 to 2 inches of hair from the scalp or body hair may be used. Tests can detect drugs, alcohol/ETG, or other tailored hair testing choices.
The use of hair follicle drug testing has become more common in recent years. Various employers, courts, and Substance Abuse professionals opt for a hair drug test over the standard urine test. Hair follicle tests are favored by employers with zero-tolerance policies, courts, and individuals on probation because they provide a longer detection window for drug use of up to 90 days, involve an observed collection process, and are nearly impossible to falsify. However, urine tests remain the most accurate for detecting recent drug use within the past five days.

Hair testing is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair offers a prolonged record of alcohol and drug use by capturing biomarkers within the fibers of the developing hair strand. When gathered near the scalp, hair can reveal an estimated 3-month detection period for alcohol and drugs. Collection is straightforward, it is relatively challenging to tamper with, and shipping is uncomplicated.
A 1.5-inch section containing about 200 hair strands (comparable to the circumference of a #2 pencil) nearest to the scalp provides 100mg of hair, which is the preferred sample for examination and validation. For EtG, supplementary tests, or tests exceeding 10 panels, a recommendation of 150mg of the specimen is made. Using a jeweler’s scale for weighing the sample is advised. Should scalp hair be unavailable, an equivalent amount of body hair might be collected. Our reference to head hair pertains solely to scalp hair. Body hair encompasses all other types (such as facial, axillary, etc.).
Process Overview
The laboratory assessment of drug test outcomes comprises four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning covers the initial integration of a sample into a laboratory’s framework. This process involves checking that the sample was duly sealed and shipped, giving it a random LAN (Laboratory Accessioning Number), and completing any further data requirements not fulfilled by a digital chain of custody system.
Screening serves as an initial rapid assessment for substance abuse. Although it is an economical means to rule out drug use for most samples, a positive screen must be confirmed for legal admissibility. Samples that test presumptively positive during Screening necessitate further verification.
When a sample shows a presumptive positive during Screening, additional hair is extracted from the original specimen and readied for Extraction. During Extraction, drugs are isolated from hair at a significantly lower concentration compared to other methods (e.g., urine or oral fluid), accentuating why hair drug testing presents the greatest challenge among methodologies.
Affirming any positive screen outcome is conducted using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive specimens are cleansed as needed before affirmation. The comprehensive lab process from Accessioning to Confirmation is evaluated under CAP (College of American Pathologists) Hair accreditation and adheres to ISO/IEC 17025 standards.

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.
