Accredited Drug Testing offers a comprehensive hair follicle drug screening service in Walnut Grove, Missouri. Whether you require a hair test for drugs or alcohol, our expertise in hair testing is available in every city throughout the nation, where tests can be conducted. Generally, hair from the crown that measures 1.5 to 2 inches, or body hair, is adequate for most scenarios. Hair tests can detect drugs, alcohol/ETG, or other personalized hair testing programs.
Recently, hair follicle drug testing has become a more prevalent method of substance screening. Numerous employers, judicial systems, and substance abuse experts prefer hair drug tests over typical urine tests. Employers with zero-tolerance drug policies, courts, and individuals under probation supervision often employ hair follicle tests. A hair follicle drug test's key advantage is its longer detection period, which usually extends up to 90 days. The tests are observed during collection, making them extremely difficult to falsify. For detecting drug use within the preceding five days, however, urine tests still provide the greatest accuracy.

Hair analysis is recognized as an effective method for identifying drug and alcohol consumption. Hair retains a chronological record of alcohol and drug use by incorporating biomarkers into the hair's growing fibers. When cut close to the scalp, hair can offer a potential detection period of around three months for alcohol and drugs. Collection is straightforward, adulteration is challenging, and shipping is efficient.
An ideal sample comprises a 1.5-inch length of approximately 200 hair strands (about the thickness of a #2 pencil) from near the scalp, yielding 100mg of material suitable for both initial screening and subsequent confirmation. For EtG, add-ons, and tests beyond 10 panels, 150mg is ideal. It's advisable to measure the sample using a jeweler’s scale. In the absence of scalp hair, an equivalent quantity of body hair can be used. By "head hair," we specifically mean scalp hair. "Body hair" encompasses all other types (facial, axillary, etc.).
Process Overview
The lab processing of a drug test result includes four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the entry of a sample into a lab's system. This entails confirming the sample was properly sealed and transported, assigning a LAN (Laboratory Accessioning Number), and completing any necessary data entry absent from an electronic custody system.
Screening constitutes an initial simple test for drugs of abuse. While it's a practical way to eliminate drug use in most cases, a positive screen requires confirmation for court validity. Any Screening presumptively positive samples must undergo further confirmation.
If a sample is presumptively positive in Screening, further hair is extracted from the original sample for the Extraction phase. Drugs are then extracted from hair at a lower concentration than detected through other methods (such as urine or oral fluids), reflecting the complexity of hair testing.
Confirmation of any positive screening is done using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples are washed pre-confirmation as appropriate. The full procedure from Accessioning through Confirmation is audited under both CAP (College of American Pathologists) Hair protocols and the ISO / IEC 17025 accreditation standards.

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.
