Whether it's for drugs or alcohol, our expertise lies in hair testing, with centers nationwide ready to facilitate these tests. Typically, 1.5 to 2 inches of hair from the head or body is required. Our tests detect drugs, alcohol/ETG, and offer specialized hair testing solutions.
Recently, the hair follicle drug test has gained traction as a preferred method of drug screening. Increasingly, employers, judicial systems, and Substance Abuse experts are opting for hair tests over traditional urine tests. This test is favored by entities with strict no-drug-use rules due to its extensive 90-day detection window, strict observation during collection, and nearly foolproof resistance to tampering. However, for drug use within a 5-day period, urine tests remain the most precise option.

The analysis of hair has become recognized as an effective method for detecting drug and alcohol usage. Hair contains a long-term record of alcohol and other substances because it captures biomarkers within the fibers of the growing hair strand. When taken near the scalp, hair can present up to roughly a 3-month window for detecting alcohol and other substances. Hair is easy to collect, relatively hard to tamper with, and convenient to transport.
A sample of 1.5 inches comprising around 200 hair strands (approximately the diameter of a #2 pencil) nearest to the scalp will yield 100mg of hair, the ideal specimen for screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, a specimen of 150mg is advised. We suggest measuring the specimen with a jeweler’s scale. Should scalp hair not be accessible, an equivalent quantity of body hair can be collected. When mentioning head hair, it refers strictly to scalp hair. Body hair includes other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test encompasses four main steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial integration of a sample into a laboratory’s system. This step checks that the sample was sealed and transported correctly, assigns a random LAN (Laboratory Accessioning Number), and fills in any additional data entry absent from an electronic chain of custody system.
Screening involves an initial rapid assessment for drugs of abuse. Though Screening is a cost-efficient method to rule out drug usage for most samples, a positive screen must be validated to be acceptable in court. Any samples that are presumptively positive in Screening indeed require secondary confirmation.
If a sample turns out presumptively positive in the Screening phase, additional hair is extracted from the original specimen for Extraction. During this phase, drugs are extracted from hair at a lower concentration compared to other methodologies (e.g., urine or oral fluid), which is why hair drug screening is regarded as the most challenging methodology to execute.
Confirmation of any positive screening result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are presumptive positive are cleaned before confirmation as necessary. The complete laboratory process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.
Advantages of hair drug testing:
Limitations:
Note: Although typically referred to as "hair follicle tests", the test evaluates the hair strand and 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.
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. The manuscripts provide valuable insights into novel analytical techniques, biomarkers, pharmacokinetics, forensic applications, and ethical considerations. As we embrace these advancements, we pave the way for a safer, healthier society, where drug testing and analysis serve as powerful tools in protecting public health and maintaining integrity in various sectors. The research presented in this special issue will undoubtedly shape the future of drug testing and analysis, fostering collaboration and inspiring further innovation in this crucial area of scientific inquiry.
