Accredited Drug Testing offers comprehensive hair follicle drug assessments in Johnstonville, California. If a hair drug or alcohol assessment is needed, Accredited Drug Testing focuses on hair evaluations, with facilities nationwide proficient in executing hair assessments. Generally, 1.5 to 2 inches of head or body hair is required. These assessments are applicable for drug and alcohol/ETG analysis, alongside other specialized testing options.
Recently, drug testing methods have increasingly integrated hair follicle tests. Numerous employers, legal entities, and Substance Abuse experts now mandate hair tests instead of typical urine tests. These hair tests are favored by entities with strict drug policies, judicial systems, and probationary services. A significant advantage is the extended drug detection period, spanning up to 90 days, with supervised collection, making it highly tamper-resistant. Nonetheless, for recent drug use analysis up to 5 days, urine tests remain more precise.

Hair analysis is increasingly viewed as a potent method for identifying drug and alcohol consumption. Hair captures a prolonged history of substance use by embedding biomarkers within the fibers of the growing strand. When hair is taken close to the scalp, it can offer an approximate 3-month detection span for substances. Hair is easy to collect, somewhat challenging to tamper with, and simple to ship.
A sample measuring 1.5 inches with roughly 200 hair strands (similar to a #2 pencil in size) closest to the scalp yields 100mg of hair, which is the perfect sample size for both screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, collecting 150mg of the specimen is advisable. It is advised to use a jeweler’s scale to weigh the specimen. If scalp hair is not available, a similar quantity of body hair may be used. When speaking about head hair, we mean only scalp hair. Body hair encompasses all other types of hair (facial, axillary, etc.).
Process Overview
The primary steps in the laboratory handling of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial handling of a specimen within a lab’s system. This process involves confirming the proper sealing and shipment of the sample, allotting a random LAN (Laboratory Accessioning Number), and completing any further data entry not covered by an electronic chain of custody system.
Screening consists of a preliminary fast check for substances. While this is a cost-effective means to negate drug use in the majority of instances, a positive result must be verified for legal admissibility. Any samples that test presumptively positive in Screening require additional confirmation.
If a specimen tests presumptively positive during Screening, more hair is taken from the original sample for Extraction. This process extracts substances from hair at a much lower concentration compared to other methods (e.g., urine or oral fluid), which makes hair drug analysis the most challenging method to execute.
The Confirmation of any positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are presumptively positive undergo a wash before confirmation if necessary. The entire lab operation from Accessioning to Confirmation is scrutinized under the guidelines of both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 accreditation.

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.
