Accredited Drug Testing offers comprehensive hair follicle drug testing services in Big Bend, California. If you require a hair-based drug or alcohol screening, our team specializes in this field, with testing centers available nationwide in all cities. Typically, having 1.5 to 2 inches of hair is necessary either from the crown of the head or the body, suitable in most scenarios. Hair tests can be customized to detect drugs, alcohol/ETG, or other specific requirements.
In recent times, the trend for drug testing has increasingly included hair follicle analysis. Multiple employers, judicial systems, and Substance Abuse experts now prefer hair drug tests over the usual urine tests. Companies with strict no-drug policies, judicial courts, and those managing probation cases find hair tests invaluable. A significant advantage of hair follicle testing is its prolonged detection window, which generally covers up to 90 days and is collected under supervision, making it extremely difficult to falsify. However, for drug use detection within the last 5 days, urine tests remain the precise choice.

Hair testing is now recognized as an effective method for identifying drug and alcohol consumption. Hair tracks a prolonged record of alcohol and drug intake by capturing biomarkers in its fibers as it grows. When taken close to the scalp, hair offers a detection period of up to roughly three months for alcohol and drugs. Its collection is straightforward, difficult to alter, and simple to mail.
A sample measuring 1.5 inches, with around 200 hair strands (approximately the thickness of a #2 pencil) near the scalp, yields 100mg of hair, which is the preferred amount for screening and validation. For tests like EtG, add-ons, and those greater than 10 panels, a 150mg sample is advised. We suggest using a jeweler’s scale for weighing. If scalp hair is unavailable, a comparable quantity of body hair may be used. The term "head hair" specifically refers to scalp hair, while "body hair" includes all other types (facial, axillary, etc.).
Process Overview
The primary stages in processing a drug test result in a laboratory are Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of the sample's initial input into a lab system. It involves verifying the sample’s proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data not provided by an electronic chain of custody.
Screening serves as a preliminary rapid check for drug abuse. While Screening can rule out drug use for most samples economically, a positive screen must be confirmed for courtroom admissibility. Presumptive positive samples require a secondary check.
If Screening's results are presumptively positive, additional hair is taken from the initial sample for Extraction. During this process, drugs are removed from the hair at concentrations much lower than other methods (e.g., urine or oral fluids), making hair drug screening highly challenging.
Positive screening results undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples are washed as necessary. Throughout, the process from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation 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.
