For individuals needing hair drug or alcohol tests, we at Accredited Drug Testing are experts in hair testing, with centers in every city throughout the Nation ready to perform such tests. Generally, you need 1.5 to 2 inches of hair from the crown of your head, but body hair is also acceptable in many instances.

Lately, drug testing methods have increasingly incorporated hair follicle tests. Many businesses, court systems, and substance abuse experts are opting for hair drug tests over traditional urine tests. Hair follicle tests are favored by employers with strict no-drug policies, judicial systems, and those on probation. Their main advantage is the extended detection window for drug use, which can track up to 90 days, is conducted through an observed collection process, and is almost cheat-proof. However, for detecting recent drug use within the last five days, urine tests remain more precise.

Seen as a potent method, hair analysis offers a means to uncover the history of drug and alcohol consumption. The strands serve as a record by capturing various substance indicators within the fibers of developing hair. Acquired near the skin, hair testing can reveal substance use over an approximate time frame of three months. Collecting hair is straightforward, somewhat resistant to tampering, and convenient for transportation.
A 1.5-inch lock containing roughly 200 hairs (comparable to the thickness of a #2 pencil) taken near the scalp provides 100mg, which is the prime sample amount for testing. For EtG, added on tests, or panels exceeding 10, 150mg of hair is advised. Utilizing a jeweler’s scale for weighing is recommended. Should scalp hair be unavailable, a similar amount from elsewhere on the body might be collected. Any mention of head hair is specific to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The drug test laboratory procedures comprise four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning represents the initial handling of a sample within a lab’s procedure. It ensures that the sample was sealed and sent correctly, assigns an arbitrary LAN (Laboratory Accessioning Number), and completes any pending data entries absent from an electronic custody chain system.
The Screening phase serves as a preliminary examination for substance misuse. Although Screening offers a cost-efficient method to dismiss drug use in most cases, court-validity necessitates confirming positive results from Screening. Each presumptive positive from Screening must go through a secondary confirmatory test.
Samples presuming positive in the Screening step require additional hair for the Extraction process. During Extraction, drugs are retrieved from hair at significantly reduced concentrations compared to other techniques (e.g., urine or saliva), contributing to the challenges of executing hair drug screenings effectively.
Any Screening presumptive positive leads to Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS methods. Relevant presumptive samples undergo washing before Confirmation as deemed necessary. The entire lab protocol, from Accessioning to Confirmation, complies with the CAP (College of American Pathologists) Hair designation alongside ISO/IEC 17025 accreditation.

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.
