Accredited Drug Testing offers comprehensive hair follicle drug screening services in Bellaire, TX. Whether seeking a hair drug or alcohol test, our expertise in hair testing is unparalleled, with facilities available in every city across the country to carry out such tests. Typically, 1.5 to 2 inches of hair from the head or body are required. This method can detect drugs, alcohol/ETG, and tailor other specific testing options to suit needs.
Recently, the preference for conducting drug screenings has shifted toward using hair follicle tests. They are becoming the go-to choice for many employers, legal entities, and addiction specialists opposed to traditional urine tests. Hair follicle testing is adopted by those with strict no-drug policies, judiciary bodies, and probation cases due to their extensive detection period—often reaching 90 days—and the secure observation process during collection, making them very difficult to manipulate. Conversely, for detecting drug use within the last five days, urine testing remains superior.

Hair analysis is regarded as a robust method for identifying drug and alcohol consumption. Hair retains a long-term chemical history of substances by capturing biomarkers within the fibers of the growing strand. When acquired near the scalp, hair can provide a detection period of up to around three months for alcohol and other drugs. Collecting hair is straightforward, challenging to tamper with, and simple to mail.
Acquiring a 1.5-inch segment of roughly 200 hair strands (comparable to the width of a #2 pencil) adjacent to the scalp will yield 100mg of hair, which is considered the optimal amount for both screening and confirmation. For EtG, additional tests, and tests beyond 10 panels, collecting 150mg of the sample is advisable. It’s recommended to use a jeweler’s scale for measuring the sample weight. If scalp hair isn’t an option, an equivalent amount of body hair can be used. References to head hair specifically imply scalp hair, whereas body hair encompasses all other types (such as facial, axillary, etc.).
Process Overview
The drug test result process in the laboratory is composed of four key phases: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample undergoes initial system processing in the lab. This phase includes ensuring the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any required data entry not encompassed by an electronic chain of custody protocol.
Screening constitutes a preliminary evaluation for drugs of abuse. Although Screening serves as a cost-effective method to dismiss drug use for most samples, a positive screen necessitates confirmation for legal admissibility. Samples that are suspected to be positive in Screening require further confirmation.
Upon a presumptive positive result in Screening, additional hair is retrieved from the initial sample and set up for Extraction. In this phase, drugs are extracted from hair at a much lower concentration compared to other methodologies (for example, urine or oral fluid), which contributes to hair drug testing being the most challenging method to execute.
Confirmation of positive Screening outcomes is executed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples are washed before confirmation if necessary. The comprehensive laboratory process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Although commonly referred to as "hair follicle tests," the analysis actually examines 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 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.
