Accredited Drug Testing offers comprehensive hair follicle drug tests in Circleville, Texas. If you're in need of a drug or alcohol hair test, we specialize in these tests, with centers located in cities across the nation capable of conducting them. Generally, you need 1.5 to 2 inches of hair on your head or body. Hair testing can detect drugs, alcohol/ETG, and other custom hair test options.
Lately, hair follicle drug testing has become more common in drug testing protocols. Many employers, court systems, and Substance Abuse Professionals now prefer hair drug tests over urine tests. These tests are chosen by employers with strict drug-free policies, legal entities, and probationary monitoring agencies. The main advantage of hair testing is the extended detection window for drug use, typically up to 90 days. This method is done under observation and is almost impossible to tamper with. However, for detecting drug use within the past 5 days, urine tests remain the most accurate.

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. It offers a comprehensive timeline of alcohol and drug intake by capturing biomarkers within the fibers of the growing hair shaft. When sampled near the scalp, hair allows for an approximate 3-month timeframe for detecting substances. Hair is straightforward to collect, not easily tampered with, and convenient for shipping.
An optimal sample consists of a 1.5-inch section with roughly 200 hair strands (about #2 pencil thickness) closest to the scalp, amounting to 100mg of hair, which is ideal for both screening and confirmation. For EtG tests, add-ons, or panels exceeding 10, a specimen weighing 150mg is advised. Utilizing a jeweler's scale for weighing the hair is suggested. If scalp hair is unavailable, a similar quantity of body hair can be used. "Head hair" refers exclusively to scalp hair, whereas "body hair" includes all other types (facial, axillary, etc.).
Process Overview
The key stages in the lab analysis of a drug test result involve Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the preliminary processing of a sample into the lab's system. This process ensures the sample is properly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and finalizes any additional data input if not already covered by an electronic chain of custody.
Screening provides a preliminary check for drug abuse. Although cost-effective for ruling out drug use in most samples, any positive findings in Screening need confirmation for legal admissibility. Samples testing presumptively positive in Screening necessitate additional verification.
Presumed positive samples in the Screening phase require extra hair extraction from the original sample for the Extraction stage. During this stage, drug traces are extracted from hair at much lower concentrations compared to other methods (ex. urine or oral fluid), which explains why hair drug screening is among the most complex methodologies.
Positive screening results are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives receive a wash prior to confirmation as needed. The complete laboratory workflow from Accessioning to Confirmation undergoes review under both CAP (College of American Pathologists) Hair criteria and accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Referred to commonly as "hair follicle tests", the actual test examines the hair strand, not the follicle below the scalp.

The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.
It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.
Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. 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.

This is by far the easiest way to get my lab work ordered and paid for. The phone calls are short and to the point. They don’t try to push extra sales on you and when I walk in to the clinic I simply show my donor pass and with in a matter of minutes I’m done. I will continue to use ADT in the future.
