Accredited Drug Testing provides comprehensive hair follicle drug testing services in Plano, Texas. Whether you require a hair drug or alcohol test, Accredited Drug Testing is a leader in hair testing, and operates testing facilities in cities across the United States capable of conducting a hair test. Generally, 1.5 to 2 inches of hair from the scalp or body is necessary. Hair tests offer the ability to check for drugs, alcohol/ETG, or other specific testing options.
More recently, the technique of performing drug tests has increasingly included hair follicle drug testing. A growing number of employers, judicial systems, and substance abuse professionals are opting for hair drug tests over traditional urine tests. Employers with zero-tolerance policies on drug use, legal institutions, and individuals on probation commonly utilize hair follicle drug tests. The key advantage of hair follicle drug testing is its extended detection range for drug consumption, typically up to 90 days, collected under inspection, making it nearly foolproof. However, when it comes to detecting drug use within the past 5 days, urine tests remain the gold standard.

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 recognized as a robust method for identifying drug and alcohol consumption. Hair effectively captures biomarkers within its fibers, providing a comprehensive, long-term record of substance use. When sampled near the scalp, hair can offer a detection time frame of up to about three months for both alcohol and drugs. The collection process for hair is straightforward, resistant to tampering, and shipping is uncomplicated.
Taking a 1.5-inch segment, comprising roughly 200 hair strands (similar in diameter to a #2 pencil) from close to the scalp will yield 100mg of hair, which is the optimal quantity for both screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, a specimen weight of 150mg is advised. Using a jeweler’s scale to weigh the specimen is recommended. If scalp hair is not an option, a comparable quantity of body hair can be collected. When we mention head hair, we refer exclusively to scalp hair, whereas body hair encompasses all other varieties (e.g., facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result comprises four pivotal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage, where a sample is integrated into a laboratory's system. This step involves verifying proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any necessary data entry that an electronic chain of custody system does not provide.
Screening provides a preliminary assessment for substances of abuse. Though an economical approach to ruling out drug use in most samples, any positive screening result must be validated to hold up in legal settings. Samples that indicate a presumptive positive in Screening need an additional confirmation step.
Should Screening suggest a presumptive positive, additional hair is sourced from the original sample for Preparation for Extraction. During this stage, substances are extracted at a notably lower concentration from hair compared to other methods (such as urine or oral fluid), highlighting the complexity of performing hair drug screenings.
Confirmation is executed via GC/MS, GC/MS/MS, or LC/MS/MS for any positive screening results. Prior to confirmation, all presumptive positive samples undergo washing when necessary. The entire laboratory process, from Accessioning through to Confirmation, is conducted under the oversight of both the CAP (College of American Pathologists) Hair designation and accreditation to ISO/IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although these are often termed "hair follicle tests," the analysis is performed on the hair strand itself, not on 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.
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. The manuscripts provide valuable insights into novel analytical techniques, biomarkers, pharmacokinetics, forensic applications, and ethical considerations.
