In Winthrop, Iowa, Accredited Drug Testing offers comprehensive hair follicle drug testing services. If a hair drug or alcohol test is needed, our expertise lies in hair testing. We have nationwide testing centers capable of conducting these tests. A 1.5 to 2-inch hair length on the head or body can be evaluated in most scenarios, enabling detection of drugs, alcohol/ETG, or other tailored hair testing solutions.
Recently, hair follicle drug tests have become a more common method for drug screening. Instead of standard urine tests, many employers, courts, and substance abuse experts now prefer hair drug tests. These tests are favored by employers with strict no-drug policies, courts, and individuals on probation. The main advantage is the extended detection window, which lasts up to 90 days, while also being administered through observed collection, making it very difficult to tamper with. Nevertheless, urine tests remain the most precise method for detecting drug use within the last 5 days.

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 testing is widely recognized as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged history of alcohol and drugs by embedding biomarkers in the fibers of the developing hair strand. When collected near the scalp, it can offer roughly a 3-month detection span for alcohol and drugs. Hair is straightforward to collect, somewhat resistant to tampering, and easy to transport.
A 1.5-inch segment of approximately 200 hair strands (about the diameter of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal sample size for screening and verification. For EtG, add-ons, and/or tests beyond 10 panels, a 150mg sample is suggested. We advise using a jeweler’s scale for weighing the specimen. If head hair is not available, a comparable quantity of body hair can be used. The term "head hair" refers to scalp hair only, while "body hair" pertains to all other hair types (facial, axillary, etc.).
Process Overview
The four core steps in the laboratory processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary processing of a sample within a lab’s system. This process involves ensuring the sample was properly sealed and shipped, generating a random LAN (Laboratory Accessioning Number), and completing any extra data entry not covered by an electronic chain of custody system.
Screening conducts an initial quick assessment for drugs of abuse. While Screening is a cost-friendly way to dismiss drug usage in most samples, a positive screen requires confirmation to be valid in court. Any samples deemed presumptively positive during Screening need a subsequent confirmation.
If a sample tests presumptively positive in Screening, more hair is taken from the initial sample for Extraction. During this phase, drugs are extracted from hair at a lower concentration than in other methods (e.g., urine or oral fluid), making hair drug analysis the most challenging methodology to execute.
Confirmation of any positive Screening result uses GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation as needed. The complete laboratory workflow from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Though frequently termed "hair follicle tests", the analysis actually examines the hair strand and not the follicle below the scalp.

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.
