Accredited Drug Testing provides comprehensive hair follicle drug tests in Agency, Iowa. For anyone requiring a hair drug or alcohol screening, our expertise lies in hair testing. We maintain testing facilities nationwide, including all cities, ready to conduct hair analyses. Typically, 1.5 to 2 inches of hair from the crown or body is necessary. Hair samples can be examined for drugs, alcohol/ETG, or other custom testing options.
Recently, drug testing methods have increasingly utilized hair follicle tests. Many employers, legal systems, and substance abuse professionals now prefer hair testing over traditional urine tests. Employers with zero-tolerance policies, courts, and individuals on probation favor this method. The major advantage of hair follicle tests is the extensive detection range—up to 90 days—collected under observation, nearly eliminating the chance of tampering. For detecting usage within the past 5 days, urine tests remain unrivaled.

When you're searching for hair drug testing near me or hair drug testing locations, we provide a simple and convenient process to find a drug and alcohol testing location near you that is certified to provide all of your drug and alcohol testing needs.
Hair tests have emerged as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged history of substances by encasing biomarkers within the fibers of the growing hair shaft. When taken near the scalp, hair offers nearly a 3-month detection timeframe for alcohol and drug use. Hair collection is straightforward, challenging to tamper with, and easy to transport.
A 1.5-inch segment of roughly 200 hair strands (comparable to the size of a #2 pencil) closest to the scalp will yield 100mg of hair, which is the perfect sample size for both screening and confirmation. For EtG, additional tests, and/or assessments exceeding 10 panels, 150mg of the hair sample is advised. We suggest using a jeweler’s scale for weighing the sample. If scalp hair is inaccessible, a similar weight of body hair can be gathered. When discussing head hair, we mean scalp hair strictly. Body hair includes every other hair type (facial, axillary, etc.).
Process Overview
There are four crucial stages in the lab process for evaluating a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the introductory processing of a sample into a lab's framework. It encompasses confirming that the sample was correctly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and filling out any extra data entry not facilitated by an electronic chain of custody system.
Screening performs an initial swift assessment for drugs of abuse. While Screening offers a cost-efficient means to eliminate drug use in the majority of samples, a positive screen needs verification to be valid in legal settings. Any samples that test tentatively positive in Screening need a follow-up confirmation.
If a sample proves tentatively positive during Screening, more hair is taken from the initial sample and prepared for Extraction. During this phase, drugs are withdrawn from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluids), making hair drug testing the most complex methodology.
Verification of any positive screening outcome is done using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results are cleansed before confirmation as required. The entire lab process, from Accessioning to Confirmation, is scrutinized 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.
