Accredited Drug Testing provides comprehensive hair follicle substance checks in Clark, South Dakota. If you're seeking a hair-based drug or alcohol examination, our expertise is in hair assessments, available through our nationwide centers. A hair length of 1.5 to 2 inches from the head or body is generally required. These tests can detect drugs, alcohol/ETG, or be tailored for other hair testing needs.
Recently, drug testing methods have increasingly embraced the hair follicle approach. Many employers, legal systems, and addiction specialists are opting for hair drug analyses over traditional urine tests. Hair tests appeal to employers with strict no-drug-use policies, legal bodies, and those overseeing probation. Their primary advantage lies in extending detection to about 90 days, with observed sample collection making deception nearly impossible. Yet, for drug use within a 5-day frame, urine tests remain the most precise.

Considered a robust method, hair testing serves to detect drug and alcohol usage effectively. The strands of hair, by capturing biomarkers within their fibers, give a long-term insight into alcohol and other drug use. Hair taken close to the scalp can reveal a detection timeframe of nearly three months for these substances. Collecting hair is straightforward, challenging to tamper with, and convenient to send off.
For screening and confirmation, a 1.5-inch sample comprising roughly 200 hair strands (similar to the thickness of a #2 pencil) adjacent to the scalp will yield approximately 100mg of hair, an optimal sample size. In cases of EtG, add-ons, and/or tests exceeding 10 panels, a specimen quantity of 150mg is suggested. Utilizing a jeweler’s scale for weighing the sample is advisable. Should scalp hair be unavailable, equivalent body hair may be collected. When we mention head hair, it pertains strictly to scalp hair. Alternatively, body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The primary four steps in laboratory processing for a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning signifies the first-step processing of a sample within a laboratory's system. This phase ensures the sample was properly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data input not covered by an electronic chain of custody system.
Screening represents an initial swift exam to detect drug abuse. While Screening is a cost-effective method for eliminating drug use across most samples, a positive screen must be substantiated to be permissible in court. Any samples showing presumptive positivity in Screening necessitate further confirmation.
If Screening suggests a sample is positive, additional hair is extracted from the original specimen for the Extraction phase. During this stage, drugs are drawn out from hair at a concentration lower than seen in other methods (such as urine or oral fluid), thus marking hair drug screening as the most complex methodology to execute.
Confirmation of any positive screening outcome is performed utilizing GC/MS, GC/MS/MS, or LC/MS/MS. Any presumingly positive samples are cleansed before confirmation as required. The comprehensive laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 accreditation.

Note: Although termed as "hair follicle tests", the analysis actually involves the hair strand and not the 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 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.
