Accredited Drug Testing offers comprehensive hair follicle drug tests in Evergreen, Missouri. If a hair drug or alcohol test is required, our facility excels in this method, with testing centers available in cities across the country. Typically, 1.5 to 2 inches of hair on the scalp or body is preferred. Hair tests can analyze drugs, alcohol/ETG, or other specialized options.
In recent times, hair follicle tests have become a more popular choice for drug screening. More and more employers, judicial systems, and specialists in Substance Abuse demand a hair drug exam rather than the traditional urine analysis. This method serves those with strict drug-free policies, aiding by providing a longer detection duration, usually up to 90 days, collected through a supervised process that is very challenging to manipulate. Conversely, for identifying recent drug use within a five-day window, urine tests remain more precise.

Hair testing is recognized as a highly effective means for detecting drug and alcohol consumption. By capturing biomarkers in the fiber of growing hair, it provides a prolonged history of substance use. When obtained near the scalp, hair samples can reveal up to a three-month period of drug or alcohol detection. Additionally, hair samples are easy to collect, hard to tamper with, and simple to transport.
A 1.5-inch portion of around 200 hair strands (comparable to the width of a #2 pencil) taken nearest the scalp yields 100mg of hair, which is an optimal sample size for screening and confirmation tests. For EtG, extra tests, or tests beyond 10-panel, 150mg of the sample is advisable. It is best to weigh the hair using a jeweler's scale. In cases where scalp hair is lacking, a similar amount of body hair might be used. References to head hair specifically mean scalp hair. Body hair, on the other hand, includes all other hair such as facial or underarm hair.
Process Overview
The four key phases in a laboratory drug test result processing are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the sample's initial entry into a lab system. This step ensures the sample's proper sealing and shipment, allocates a random LAN (Laboratory Accessioning Number), and fills in any missing details not included by an electronic chain of custody system.
Screening is an initial brief examination for drugs. Although cost-effective, a Screening result must undergo confirmation to be viable in a legal setting. Any samples deemed likely positive during Screening need additional verification.
If a sample shows likely positivity in the Screening phase, a further portion of hair from the original sample is taken for Extraction. This stage extracts drugs from hair at lower concentrations compared to methods such as urine or oral fluid testing, thus positioning hair drug testing as one of the most challenging to execute.
GC/MS, GC/MS/MS, or LC/MS/MS techniques authenticate any positive Screening results. Presumptive positive samples undergo washing if necessary before confirmation. The comprehensive lab procedure, from Accessioning through Confirmation, is supervised under both CAP (College of American Pathologists) Hair designation and accredited to ISO / IEC 17025 standards.

Note: Despite commonly being called "hair follicle tests," the test focuses on analyzing the hair strand 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.
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.
