In Marthasville, Missouri, Accredited Drug Testing offers comprehensive hair follicle drug testing services. Specializing in hair analyses, we cater to both hair drug and alcohol testing needs. Our facilities span cities nationwide, capable of conducting hair tests. Typically, 1.5 to 2 inches of hair from the head's crown or any body part is needed. Our tests can check for drugs, alcohol/ETG, or be customized for specific needs.
Lately, hair follicle drug testing has been increasingly favored for drug screenings. Employers, legal systems, and substance abuse experts often opt for hair tests over urine tests. Companies with zero-tolerance policies, courts, and probation officers find these tests invaluable. They detect drug use over a longer span—up to 90 days—with observed collection, making them tamper-proof. For recent drug use, though, urine tests remain the most precise choice within five 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.
Recognized as an effective method for detecting drug and alcohol consumption, hair testing captures a long-term record by embedding biomarkers within the strands of hair as they grow. By obtaining hair samples close to the scalp, it's possible to detect substances up to a span of three months. Hair is straightforward to collect, challenging to tamper with, and convenient for shipping.
A 1.5-inch segment consisting of roughly 200 hairs (comparable in size to a #2 pencil) cut nearest to the scalp can yield 100mg, which is ideal for initial testing and validation. For tests like EtG and those exceeding 10 panels, 150mg of the sample is advisable. It's suggested to weigh the sample using a jeweler’s scale. In the absence of scalp hair, a similar quantity of body hair is acceptable. When discussing head hair, we specifically refer to scalp hair. Body hair encompasses all other types (facial, underarm, etc.).
Process Overview
The laboratory analysis of drug test results comprises four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the foundational handling of a sample within the lab’s framework. This includes ensuring the sample was adequately sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and executing any supplementary data input not covered by an electronic chain of custody protocol.
Screening provides an initial, swift assessment for substance abuse indicators. Although Screening efficiently eliminates drug use in the bulk of samples, confirmatory testing is required for court admissibility of a positive result. Samples with presumptive positives in Screening necessitate further confirmation tests.
For samples that show presumptive positives during Screening, additional hair is taken from the initial sample for preparation in the Extraction stage. At this point, drugs are retrieved from hair at markedly lower concentrations than other methods (such as urine or saliva), presenting challenges in performing hair drug tests.
The Confirmation step for any positive results detected during screening uses GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples undergo washing before confirmation as necessary. The entire testing process, from Accessioning to Confirmation, is examined under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Limitations:
Note: Though frequently referred to as "hair follicle tests", the analysis focuses on the hair strand itself rather than the follicle beneath 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.
