Accredited Drug Testing offers comprehensive hair follicle drug tests in Northwest Harris, Texas. Whether you require a test for drugs or alcohol, our expertise is in hair testing, with facilities nationwide capable of conducting these tests. Generally, 1.5 to 2 inches of hair from the head or body is needed. Hair tests can detect drugs, alcohol/ETG, or be customized for other analyses.
Recently, hair follicle drug testing has become more prevalent. Employers, courts, and Substance Abuse experts often choose a hair drug test over the traditional urine test. Those with strict no-drug policies, as well as courts and probationers, prefer hair follicle drug tests due to their longer detection window of up to 90 days, observed collection process, and resistance to tampering. Nevertheless, urine tests are more accurate for drug use within the past 5 days.

When you're searching for hair drug testing near me or hair drug testing locations, we provide a simple and convenient process to find a drug and alcohol testing location near you that is certified to provide all of your drug and alcohol testing needs.
Hair testing is now considered an effective method for identifying drug and alcohol consumption. The hair captures biomarkers in its fibers, offering a lengthy timeline of alcohol and drug use history. When hair is collected near the scalp, it can reveal drug and alcohol usage for up to three months. This method of collection is easy, hard to tamper with, and convenient to ship.
For optimal screening and confirmation, a 1.5-inch sample, ideally weighing 100mg, from approximately 200 individual hairs near the scalp (comparable to a #2 pencil) is suggested. If testing for EtG, additional substances, or panels beyond 10, a 150mg sample is preferred. We advocate for using a jeweler’s scale to weigh the sample. If scalp hair cannot be obtained, a similar volume of body hair is acceptable. When we mention head hair, we’re specifically referring to the scalp hair. Body hair involves all other types, such as facial or axillary hair.
Process Overview
The laboratory analysis of a drug test result involves Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first phase, where a sample enters the lab system. This step includes checking that the sample was appropriately sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any remaining data entry absent from an electronic custody system.
Screening provides an initial, rapid assessment for drugs. Although Screening is an economical way to dismiss drug usage for many samples, a positive result requires confirmation for court validity. Samples flagged positive during Screening need further confirmation.
If a sample tests positive in Screening, the initial sample is used to procure more hair for Extraction. This step removes drugs from hair at significantly lower concentration levels compared to other methods (e.g., urine or oral fluid), making hair drug screening a challenging practice.
GC/MS, GC/MS/MS, or LC/MS/MS techniques are used to confirm any positive screening outcomes. All samples that are presumptively positive undergo washing as necessary before confirmation. The sequence of laboratory procedures from Accessioning to Confirmation is evaluated under both CAP (College of American Pathologists) Hair guidelines and the ISO / IEC 17025 accreditation.

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.
