Accredited Drug Testing offers comprehensive hair follicle drug assessments in De Smet, South Dakota. For those needing a hair-based drug or alcohol screening, our expertise in hair testing spans our nationwide network of testing sites. Typically, hair samples of 1.5 to 2 inches from the scalp or body are required. These tests can detect substances, including drugs and alcohol/ETG, with custom options available.
In recent times, hair follicle testing has increasingly become a favored method for drug screenings. Many employers, judiciary circuits, and addiction specialists now prefer hair drug tests over traditional urine analyses. Hair follicle testing is chosen by organizations with strict anti-drug regulations, courts, and those under probation. Its notable advantage is the extended detection window, capturing drug use over approximately three months, made robust by the observed collection process and its resistance to manipulation. However, for drug consumption within five days, urine tests still remain the gold standard for accuracy.

Hair testing is increasingly recognized as a significant method for detecting drug and alcohol usage. The hair can provide an extended timeline of alcohol and drug presence by incorporating biomarkers within the strands of the growing hair. When sampled close to the scalp, hair can offer a detection period of up to roughly three months for alcohol and other drugs. Collecting hair is straightforward, moderately challenging to tamper with, and convenient for shipping.
A 1.5-inch sample consisting of around 200 hairs (comparable to a #2 pencil in thickness) near the scalp yields 100mg of hair, which is the optimal amount for analysis and verification. For EtG, add-ons, and/or examinations exceeding 10 panels, a specimen amount of 150mg is advised. It is suggested to measure the sample on a jeweler’s scale. If scalp hair isn't present, a comparable quantity of body hair may be used. When referring to head hair, it specifically refers to scalp hair alone. Body hair encompasses all other hair types (such as facial, axillary, etc.).
Process Overview
The main laboratory procedures in processing a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is related to the initial handling of a sample within a lab's system. This process verifies that the sample was adequately sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data input not covered by an electronic chain of custody system.
Screening is a preliminary rapid assessment for drugs of abuse. It is an economical technique to eliminate drug usage in most samples, but a positive screen requires confirmation to be court-acceptable. Any samples showing presumptive positivity during Screening require a follow-up confirmation.
If a sample shows a presumptive positive in the Screening phase, additional hair is taken from the original specimen for Extraction. At this point, drugs are extracted from hair at much lower concentrations than in urine or oral fluid, contributing to the complexity of hair drug screening.
Confirmation of positive screening results is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are presumptively positive are cleansed before confirmation as necessary. The entire lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation 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. 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.
