Accredited Drug Testing offers comprehensive hair follicle drug screenings in Trenton, Florida. For hair drug or alcohol tests, Accredited Drug Testing is the expert in hair analysis, with centers available across the country. Candidates must have 1.5 to 2 inches of hair on the scalp or body. These tests evaluate drugs, alcohol/ETG, or other specialized testing needs.
Over recent years, hair follicle drug testing has gained popularity. Employers, courts, and substance abuse experts often opt for hair tests instead of traditional urine analysis. These are preferred by entities with strict drug policies. The key advantage is a longer drug usage detection window, typically reaching 90 days, observed collection, and near-impossibility of tampering. However, for drugs consumed in the last five days, urine tests still provide the highest accuracy.

Hair testing has emerged as a formidable method for identifying substance use, including drugs and alcohol. Hair retains a longitudinal history of these substances by embedding biomarkers within its fibers as it grows. When hair is collected from near the scalp, it offers an estimated 3-month timeframe for detecting drug and alcohol usage. The collection process is straightforward, the hair is relatively resistant to tampering, and it is convenient to ship.
A hair sample measuring 1.5 inches with about 200 strands (approximately the diameter of a #2 pencil) from the scalp yields 100mg, the perfect amount for both screening and confirming tests. For EtG, add-ons, or extended panels beyond 10, a specimen weighing 150mg is advisable. It is best to use a jeweler’s scale for weighing. Should there be no available scalp hair, a similar amount of body hair can be gathered. When mentioning head hair, it specifically pertains to scalp hair, while body hair encompasses all other types (such as facial and axillary).
Process Overview
The drug testing laboratory process consists of four main stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning constitutes the preliminary handling of a sample entering a lab's system. It involves ensuring the sample’s sealing and shipping integrity, generating a random LAN (Laboratory Accessioning Number), and finishing any extra data inputs absent from an electronic chain of custody.
Screening provides an initial but rapid inspection for illicit substance presence. While it is an affordable approach to dismiss potential drug use in most samples, a positive result requires confirmation to be legally acceptable. Samples that screen positive presumptively require additional confirmation.
Upon presumptive positivity in the Screening phase, additional hair is extracted from the original sample for further preparation in the Extraction phase. In this stage, hair releases drugs at significantly lower concentrations compared to other methods (like urine or saliva); hence, hair screening stands as one of the most challenging methodologies.
Confirmation of any positive result undergoes GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples preliminarily positive are washed before final confirmation if necessary. The complete lab process, from Accessioning through Confirmation, follows rigorous review under the CAP (College of American Pathologists) Hair criteria and is accredited per ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Often labeled as "hair follicle tests," these tests actually analyze the hair strand, not the follicle beneath the scalp.

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.
