In Florence, California, Accredited Drug Testing offers comprehensive hair follicle drug tests. If a hair drug or alcohol screening is needed, our organization excels in hair testing, with facilities across all national cities that execute these tests. Generally, 1.5 to 2 inches of hair from the head or body can be utilized. Tests can pinpoint drugs, alcohol/ETG, or be customized for other hair analysis.
In recent times, the hair follicle method for drug screening has gained traction. Numerous employers, judicial bodies, and substance abuse experts prefer this over traditional urine tests. Employers with strict no-drug policies, courts, and probation programs favor hair follicle tests. Their main advantage is an elongated detection span—usually extending up to 90 days—gathered under observed conditions and hard to tamper with. Urine tests remain more accurate within a 5-day usage window.

Hair testing is increasingly regarded as an effective means for identifying drug and alcohol consumption. Hair captures a long-term history of alcohol and other substances by embedding biomarkers within the fibers of the developing hair strand. When cut near the scalp, hair can offer up to an estimated three-month detection timeframe for alcohol as well as other drugs. Hair collection is straightforward, not easily tampered with, and convenient to transport.
A 1.5-inch sample consisting of roughly 200 hair strands (similar in size to a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal sample size for analysis and verification. For EtG, additional tests, or panels exceeding ten, 150mg of the specimen is advisable. We suggest measuring the specimen weight on a jeweler's scale. If no scalp hair is accessible, an equivalent amount of body hair may be collected. When referencing head hair, this pertains exclusively to scalp hair. Body hair encompasses all other hair varieties (facial, axillary, etc.).
Process Overview
The four key stages in the laboratory processing of a drug test result encompass Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial registration of a sample into a laboratory's system. This includes confirming that the sample was correctly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and performing any supplemental data input not supplied by an electronic chain of custody system.
Screening entails an initial rapid assessment for drugs of abuse. Screening is an economical means to exclude drug usage in most samples; however, a positive screen must be verified for court admissibility. Samples that test presumptively positive in Screening require a subsequent confirmation.
If a sample is presumptively positive during Screening, additional hair is removed from the original specimen for Extraction. In this phase, drugs are isolated from hair at a much lower concentration than in other methodologies (e.g., urine or oral fluid), underscoring why hair drug screening presents greater complexity.
Confirmation of any positive screening outcome is carried out through GC/MS, GC/MS/MS, or LC/MS/MS. All samples deemed presumptively positive are cleansed before confirmation as necessary. The entire laboratory process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Note: Though commonly referred to as "hair follicle tests", the test evaluates the hair strand rather than the hair 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.
