Accredited Drug Testing provides comprehensive hair follicle drug assessments in Dallas, Pennsylvania. If a hair drug or alcohol examination is needed, Accredited Drug Testing excels in these evaluations, with available centers nationwide capable of conducting hair tests. Typically, 1.5 to 2 inches of hair from the head or body is required. Hair samples may be analyzed for drugs, alcohol/ETG, or other custom options.
Recently, the approach to drug testing has increasingly incorporated hair follicle assessments. Many employers, judicial systems, and Substance Abuse experts are opting for hair testing over the standard urine method. This test is favored by employers with strict no-drug policies, courts, and probation individuals. The chief advantage of hair follicle tests is a longer drug detection timeframe, spanning up to 90 days, with an observed collection process, and it is nearly immune to tampering. However, for drug usage within the past 5 days, the urine test remains the most precise.

Hair testing is now regarded as an effective method for recognizing drug and alcohol consumption. Hair offers a prolonged record of alcohol and drugs by capturing biomarkers within the fibers of the hair as it develops. When collected close to the head, hair can offer up to a three-month period for detecting alcohol and other drugs. Hair is straightforward to collect, not easily tampered with, and simple to transport.
A 1.5-inch segment of approximately 200 strands of hair (similar in size to a #2 pencil) nearest to the scalp yields 100mg of hair, which is the perfect sample for both screening and confirmation purposes. For EtG, additional tests, and/or analyses exceeding 10 panels, a 150mg specimen is advised. We suggest using a jeweler's scale for weighing the sample. If no scalp hair is available, an equivalent amount of body hair is acceptable. When mentioning head hair, we exclusively refer to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The procedure for processing a drug test result in the laboratory consists of four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a lab’s workflow. This comprises validating that the sample was securely sealed and shipped correctly, generating a random LAN (Laboratory Accessioning Number), and performing any extra data entry that isn't handled by an electronic chain of custody system.
Screening involves a preliminary rapid assessment for drugs of abuse. Although Screening offers a cost-effective strategy to eliminate drug use in most samples, legal cases require a positive screen to be confirmed. Samples that appear positive in Screening need subsequent confirmation.
If a sample tests presumptively positive in the Screening process, additional hair is extracted from the initial sample and set up for Extraction. In this step, drugs are retrieved from hair at lower concentrations than in other techniques (such as urine or oral fluid), which renders hair drug screening as the most intricate method to conduct.
Confirmation of any positive screen result is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumed positive samples are cleansed before confirmation if necessary. The entire process from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair designation and in accordance with ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Frequently termed as "hair follicle tests", the test primarily analyzes the hair shaft, 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.
