Whether you require a hair drug or alcohol test, Accredited Drug Testing specializes in this area, with locations in all cities Nationwide capable of conducting hair tests. Generally, samples require 1.5 to 2 inches of hair from the crown or other body areas for assessment. These tests can screen for drugs, alcohol/ETG, or other tailored hair testing needs.
Recently, drug testing methods increasingly incorporate hair follicle tests. Hair drug tests are preferred by various employers, judicial entities, and Substance Abuse professionals over typical urine tests. These tests benefit employers with zero-tolerance policies, courts, and those on probation due to their extensive detection window for drug use, typically up to 90 days, and because collections occur under supervision, making them nearly foolproof against cheating. Nonetheless, urine tests remain the most accurate for detecting recent drug use within the past five days.

The analysis of hair samples has gained recognition as an effective method for identifying drug and alcohol consumption. Hair acts as a chronic record of substances by encapsulating biomarkers within the shaft of the elongating hair. When strands are cut near the scalp, they can reveal drug and alcohol usage for up to a 90-day period. Collecting hair is straightforward, relatively tamper-resistant, and can be easily transported.
A strand sample of 1.5 inches consisting of about 200 hairs (comparable to the thickness of a #2 pencil) near the scalp yields 100mg of hair, which is optimal for both screening and confirming. For testing expansions like EtG or assays over 10 panels, 150mg of the sample is advisable. Measuring the sample with a jeweler’s scale is suggested. If hair from the scalp cannot be collected, an equivalent volume of body hair is acceptable. By "head hair," we specifically mean hair from the scalp, while "body hair" covers all other types (e.g., facial, axillary).
Process Overview
The comprehensive laboratory procedure for processing a drug test result includes Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the primary integration of a specimen into the laboratory framework. This step involves checking that the specimen was properly sealed and delivered, generating a unique LAN (Laboratory Accessioning Number), and completing any supplementary data input not facilitated by an electronic chain of custody system.
Screening provides an initial rapid assessment for the presence of drugs. Though Screening offers an economical way to identify drug consumption in most samples, any positive result must be verified to stand in a legal context. Samples yielding a positive result during Screening require a secondary verification.
For samples indicated as positive during Screening, additional hair is extracted from the initial collection and undergoes the Extraction process. Here, drugs are isolated from the hair at significantly lower concentrations than alternative methods (such as urine or saliva), making it the most challenging testing approach.
Verification of any positive Screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS technology. Every preliminary positive sample undergoes washing ahead of verification if necessary. The whole laboratory operation from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation alongside the ISO / IEC 17025 standards accreditation.

Note: Although often known as "hair follicle tests," the procedure actually evaluates the hair shaft and not the root below 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.
