In Saint Johns, Ohio, Accredited Drug Testing offers full-spectrum hair follicle drug tests. Whether you're in need of a hair drug or alcohol assessment, we are proficient in hair testing with facilities available in every city throughout the country capable of performing such tests. For most assessments, 1.5 to 2 inches of hair from the crown of the head or body is required. Hair analysis can reveal presence of drugs, alcohol/ETG, or provide custom testing options.
Recent trends in drug testing increasingly favor hair follicle assessments. Employers, judiciary, and substance abuse specialists often opt for hair tests instead of standard urine analysis. Hair follicle testing is prevalent among employers enforcing zero-tolerance policies and is utilized by courts and for probation monitoring. The key advantage of a hair test is its capability to detect drug use over a prolonged duration—usually up to 90 days—and the process is reliable as it involves direct supervision, reducing chances of tampering. Conversely, urine tests still offer greater accuracy for detecting drug use in the prior 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 recognized as an effective method for identifying drug and alcohol consumption. The fibers of growing hair strands encapsulate biomarkers, offering a long-term record of alcohol and drug use. When taken from near the scalp, hair can provide a detection window of up to about three months for alcohol and drugs. It is easy to collect, relatively hard to tamper with, and simple to transport.
A 1.5-inch sample containing about 200 strands of hair (approximately the diameter of a #2 pencil) taken from the scalp will yield 100mg of hair, which is the ideal amount for analysis and confirmation. For EtG, add-ons, or tests surpassing 10 panels, a 150mg sample is advised. We recommend using a jeweler's scale to weigh the sample. If scalp hair is not available, an equivalent amount of body hair can be collected. When we mention head hair, we refer to scalp hair only. Body hair includes all other types of hair (such as facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves initially processing a sample into a laboratory’s system. This step ensures the sample was sealed and transported correctly, assigns a unique LAN (Laboratory Accessioning Number), and completes any extra data entry that an electronic chain of custody system does not provide.
Screening is a quick preliminary test for drugs of abuse. Although Screening is an economical way to dismiss drug use in most samples, a Scanning positive test must be confirmed for it to be court-admissible. Any samples with presumptive positive results in Screening require further confirmation.
If a sample is presumptive positive during Screening, more hair is taken from the original sample and readied for Extraction. At this stage, drugs are extracted from hair at significantly lower concentrations compared to other methods (such as urine or oral fluid), making hair drug screening the most challenging method to execute.
Confirmation of any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed as required before confirmation. The complete laboratory process from Accessioning to Confirmation is reviewed under the CAP (College of American Pathologists) Hair designation and accredited to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: While often termed "hair follicle tests", the analysis is conducted on the hair strand rather than the hair follicle beneath the scalp

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.
