Accredited Drug Testing provides comprehensive hair follicle drug evaluations throughout Chestnut, Illinois. For those needing a hair or alcohol analysis, Accredited Drug Testing is a leader in hair testing, boasting facilities in cities nationwide equipped to administer such assessments. Typically, 1.5 to 2 inches of hair on the crown or body are required. These tests can check for drugs, alcohol/ETG, or other tailored hair testing options.
The prevalence of hair follicle drug tests in drug screening has grown significantly over recent years. Many employers, judicial systems, and substance abuse professionals are now opting for hair drug testing instead of conventional urine tests. These tests are favored by zero-tolerance employers, courts, and probation officers. The superior detection range of hair follicle testing—up to 90 days—alongside its observed collection process, makes it nearly impossible to cheat. However, for drug use within the past 5 days, urine tests maintain their accuracy.

Hair analysis is increasingly recognized as an effective instrument for identifying drug and alcohol consumption. Hair retains a comprehensive timeline of substance usage by embedding biomarkers within the strands as they grow. By obtaining hair near the scalp, one can achieve a detection span of up to roughly 3 months for substances. The process of collecting hair samples is straightforward, challenging to tamper with, and convenient to transport.
A 1.5-inch segment of approximately 200 hair strands (around the thickness of a #2 pencil) nearest to the scalp provides 100mg of hair — the perfect quantity for both screening and verification. For EtG, additional tests, or panels exceeding 10, a 150mg sample is advisable. It's best to measure the sample using a jeweler's scale. If scalp hair is not present, a similar amount of body hair can be utilized. When mentioning head hair, we specifically mean scalp hair. Body hair includes all other varieties like facial and axillary hair.
Process Overview
The key phases in laboratory assessment of a drug test include Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the initial phase of incorporating a sample into a lab’s framework. It involves confirming that the sample was correctly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data input absent in an electronic custody system.
Screening is a preliminary rapid test for identifying substance abuse. While Screening serves as an efficient way to dismiss substance use for most samples, a positive result must be verified to stand in legal settings. Samples showing provisional positivity in Screening need additional confirmation testing.
Should a sample indicate presumptive positivity during Screening, additional hair is taken from the original sample for Extraction. In this step, substances are extracted at a much lower concentration compared to other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug testing procedures.
Verification of any initial positive results employs GC/MS, GC/MS/MS, or LC/MS/MS. All samples with potential positivity undergo necessary washing before confirmation. The comprehensive laboratory procedure from Accessioning to Confirmation is scrutinized according to both CAP (College of American Pathologists) Hair credentials and the ISO / IEC 17025 accreditation.

Note: Despite being often called "hair follicle tests", the analysis targets the hair strand, not the follicle 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.
