At Accredited Drug Testing, we provide comprehensive hair follicle drug testing services in Houston, Minnesota. If you're in need of a hair drug or alcohol test, our expertise in hair testing is unparalleled. We operate testing centers across the nation, ready to conduct a hair test wherever you are. Typically, 1.5 to 2 inches of hair from the head or body is sufficient for analysis. These tests can detect drugs, alcohol/ETG, and offer other personalized testing options.
Nowadays, hair follicle drug tests are becoming more prevalent as a method for drug testing. Many employers, judicial systems, and substance abuse experts prefer hair testing over traditional urine tests. This test is utilized by those enforcing zero-tolerance drug policies and is nearly impossible to manipulate. The key advantage is a much longer detection range, generally up to 90 days, which is collected under strict observation. However, for detecting recent drug use within the past five days, urine tests remain more reliable.

Hair analysis has emerged as an effective means for identifying drug and alcohol consumption. Hair captures a comprehensive timeline of alcohol and substance use by embedding biomarkers within the strands of growing hair. When taken near the scalp, hair can offer an approximate 3-month window for detecting substances. Collecting hair is straightforward, challenging to tamper with, and convenient to transport.
A sample measuring 1.5 inches long and approximately 200 hairs (resembling the thickness of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is ideal for both screening and confirmation. For EtG enhancements and/or tests exceeding 10 panels, a specimen of 150mg is advised. It's recommended to weigh the sample using a jeweler’s scale. In the absence of scalp hair, collect a similar quantity of body hair. When referring to head hair, it denotes scalp hair exclusively. Body hair includes any other types (facial, axillary, etc.).
Process Overview
The entire laboratory processing of drug testing comprises four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase, introducing a sample to a laboratory’s system. This step involves ensuring the sample’s proper sealing and shipping, allotting a random LAN (Laboratory Accessioning Number), and finalizing any missed data entry omitted by an electronic chain of custody system.
Screening comprises a rapid preliminary check for drug abuse indicators. While efficient for ruling out drug use for most samples, a positive screen must be validated to be considered in court. Samples testing presumptively positive in Screening must undergo further confirmation.
Presumptive positivity during the Screening stage requires additional hair from the original sample for Extraction. Extraction involves retrieving drugs from hair at a far lower concentration than other methods (e.g., urine or oral fluid), which accounts for hair drug screening's complexity.
Positive screening confirmation involves techniques like GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as needed. The entire lab process, from Accessioning to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair certification and alignment with ISO / IEC 17025 standards.

Note: Although termed "hair follicle tests", the actual analysis pertains to the hair shaft 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.
