Accredited Drug Testing provides comprehensive hair follicle drug testing services in Holt, Missouri. Whether for drug or alcohol analysis, we are the experts in hair testing and feature centers across various cities nationwide ready to conduct tests. Typically, you'll need to have 1.5 to 2 inches of hair on the head or body to proceed. Our hair tests encompass drugs, alcohol/ETG, and specialized testing options.
Over the years, the use of hair follicle drug testing has emerged more prominently. Many organizations, legal entities, and substance abuse experts now favor it over the traditional urine tests. It is chosen by employers enforcing strict drug-free policies, courts, and for those on probation. The key advantage of hair tests is their ability to detect drug usage over a longer period, around 90 days, with strict collection integrity, making them hard to manipulate. That said, for usage within the past 5 days, urine tests are still the gold standard.

Hair testing is increasingly recognized as an effective instrument for uncovering drug and alcohol consumption. It offers a prolonged history of substance use by entrapping biomarkers within the fibers of the developing hair strand. When obtained near the scalp, hair offers a detection period of up to roughly three months for alcohol and drugs. The collection is straightforward, difficult to tamper with, and convenient to ship.
A 1.5-inch sample containing approximately 200 hair strands (roughly the thickness of a #2 pencil) closest to the scalp yields 100mg of hair, which is optimal for screening and verification. For EtG, additional tests, and analyses exceeding 10 panels, 150mg of hair is advised. It is suggested to weigh the sample using a jeweler’s scale. If scalp hair is not present, equivalent body hair can be gathered. References to head hair specifically mean scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The primary stages in lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial processing phase where a sample is recorded into a lab’s system. This step involves checking that the sample is properly sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and performing any additional data entry not handled by an electronic chain of custody system.
Screening entails an initial rapid check for drug abuse. Although Screening is an economical approach for eliminating drug usage in most samples, a positive screen requires verification for legal admissibility. Any samples preliminarily positive in Screening need a subsequent confirmation.
If a sample shows preliminary positivity in the Screening phase, additional hair is extracted from the initial sample and prepared for Extraction. In this phase, drugs are extracted from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), making hair drug screening the most challenging method to execute.
Confirmation of any positive screening is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo a wash before confirmation, if necessary. The comprehensive lab process from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO/IEC 17025 standards.

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.
