If you're seeking a hair drug or alcohol test, Accredited Drug Testing is an expert in hair testing, with locations in all cities nationwide equipped to perform hair tests. Generally, you need 1.5 to 2 inches of hair from the crown or body. Hair tests can detect drugs, alcohol/ETG, or other tailored testing options.
In the past few years, drug testing methods have increasingly involved hair follicle tests. Numerous employers, courts, and Substance Abuse professionals now prefer hair drug tests over traditional urine tests. Hair follicle tests cater to employers with zero-tolerance policies, judicial bodies, and probation compliance. Their main advantage is a longer detection timeframe, typically up to 90 days, and a monitored collection process that is nearly foolproof. Nevertheless, for detecting recent drug use within the last 5 days, urine tests still excel in accuracy.

Hair evaluations have emerged as an effective mechanism for identifying alcohol and drug consumption. Hair serves as a chronological record of alcohol and other drug usage by encapsulating biomarkers within the strands of growing hair. When obtained near the scalp, it can provide a detection period of up to roughly three months for both alcohol and various drugs. Collection of hair is straightforward, somewhat tamper-resistant, and simple to transport.
An ideal screening and confirmation hair sample consists of a 1.5-inch section of roughly 200 hair strands (comparable in size to a #2 pencil) nearest the scalp, providing about 100mg of hair. For EtG, additional tests, and/or panels exceeding 10, a 150mg specimen is advisable. Specimen measurement using a jeweler’s scale is recommended. If scalp hair is not available, an equivalent body hair amount can be collected. When discussing head hair, it specifically refers to scalp hair, while body hair encompasses all other types (like facial or axillary hair).
Process Overview
The fundamental stages in a laboratory's drug testing process include Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial integration of a sample into the laboratory's framework, which includes confirming that the sample was correctly sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry not facilitated by a digital chain of custody system.
Screening serves as a preliminary assessment for substances of abuse. Although Screening provides an economical means to rule out drug use in most samples, any positive reading must be corroborated for legal acceptance. Samples indicated as presumptive positives in Screening necessitate secondary verification.
For presumptive positives identified in Screening, more hair is extracted from the initial sample and readied for Extraction. In this phase, drugs are drawn from hair at much lower concentrations than other methods (e.g., urine or oral fluid), highlighting why hair drug screening represents a complex methodology.
The Confirmation of positive screening outcomes is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples considered presumptive positives are cleansed prior to confirmation where required. The entirety of the laboratory's process from Accessioning through Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and the 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. The manuscripts provide valuable insights into novel analytical techniques, biomarkers, pharmacokinetics, forensic applications, and ethical considerations.
