Accredited Drug Testing offers comprehensive hair follicle drug assessments in Keystone, South Dakota. If you're seeking a hair or alcohol drug test, we are experts, with facilities in cities across the nation that can facilitate hair testing. Generally, a hair length of 1.5 to 2 inches on the scalp or body is required. Hair samples can be evaluated for drugs, alcohol/ETG, or custom options.
Recently, the trend for drug testing methods increasingly involves hair follicle testing. Many companies, legal systems, and addiction specialists now favor hair drug tests over standard urine analysis. Employers with strict anti-drug policies, judicial systems, and probationers utilize these tests. The main advantage is a longer detection window, typically up to 90 days, conducted under supervision, making it highly tamper-proof. Nevertheless, for drug use detection within five days, urine tests remain the gold standard.

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 acknowledged as a potent means for identifying drug and alcohol consumption. Hair offers an extensive timeline by capturing biomarkers within the fibers as hair grows. When taken near the scalp, it can deliver up to a 3-month window of detection for drugs and alcohol. Hair collection is straightforward, challenging to tamper with, and simple to transport.
A 1.5-inch section of roughly 200 hair strands (comparable in size to a #2 pencil) nearest to the scalp will yield 100mg of hair, the perfect sample for both screening and confirmation. For EtG, additional tests, or panels exceeding 10, a 150mg sample is advisable. We suggest weighing the sample using a jeweler’s scale. If scalp hair is not accessible, an equivalent amount of body hair can be obtained. Head hair specifically refers to scalp hair, while body hair includes all other types (facial, axillary, etc.).
Process Overview
Key stages in the laboratory processing of drug tests include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial processing of a sample within a lab’s system. This step ensures the sample was properly sealed and shipped, allocates a random LAN (Laboratory Accessioning Number), and completes any additional data entry not offered by an electronic chain of custody system.
Screening entails a preliminary brief check for drugs of abuse. Although Screening effectively rules out drug usage in most samples, a positive screen must be verified for legal admissibility. Samples with a presumptive positive in Screening necessitate secondary confirmation.
If a sample shows a presumptive positive during the Screening phase, additional hair is taken from the original sample and prepped for Extraction. Here, drugs are extracted from the hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), thus making hair drug testing an intricate methodology.
Confirmation of any positive screening finding is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with a presumptive positive outcome are cleaned prior to confirmation if necessary. The entire lab process, from Accessioning to Confirmation, is audited under both the CAP (College of American Pathologists) Hair category and the accreditation to ISO / IEC 17025 standards.

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.

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.
