Accredited Drug Testing offers comprehensive hair follicle testing services in Madisonville, Texas. If you require a test for drugs or alcohol, we specialize in hair analysis and have facilities across the country, including all cities, that can conduct these tests. You need to have 1.5 to 2 inches of hair on your head or elsewhere on your body. Hair samples can be tested for drugs, alcohol/ETG, or other tailored testing needs.
Recently, hair follicle drug tests have become more prevalent in drug testing procedures. Many employers, judiciary systems, and substance abuse experts now prefer hair drug testing over the traditional urine tests. Hair tests are favored by employers with strict drug-free policies, legal authorities, and those on probation. The notable advantage of hair drug tests is the extended drug detection period, lasting up to 90 days, with the samples being collected under supervision, making it nearly foolproof against attempts of cheating. Nevertheless, urine tests remain superior for identifying recent drug use within the past 5 days.

Hair evaluation is now regarded as an effective means for identifying substance and alcohol consumption. Hair holds an extended timeline of alcohol and substances by integrating biomarkers into the fibers of the developing hair shaft. When obtained near the scalp, hair can disclose a detection period of up to three months for alcohol and other substances. Hair collection is straightforward, relatively hard to alter, and straightforward to transport.
A 1.5-inch segment of roughly 200 hair strands (comparable to a #2 pencil) nearest to the scalp offers about 100mg of hair, which is the optimal amount for preliminary and confirmation assessment. For EtG, supplementary examinations, and/or tests exceeding 10 panels, 150mg of the sample is advisable. Using a jeweler’s scale to weigh the sample is suggested. If head hair is not available, an equivalent measure of body hair can be acquired. Scalp hair refers specifically to head hair, while body hair covers all other types like facial or axillary hair.
Process Overview
The procedure for processing a laboratory drug test entails four critical steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial integration of a specimen into a laboratory’s framework. This step includes confirming the sample’s proper sealing and shipment, allocating a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry absent from an electronic chain of custody system.
Screening involves a preliminary swift inspection for substance misuse. While Screening offers an economical method to exclude drug consumption in most specimens, a positive result requires confirmation for legal acceptability. Samples preliminarily positive in Screening necessitate subsequent corroboration.
If a specimen is preliminarily positive in the Screening phase, additional hair is extracted from the initial sample and readied for Extraction. During this stage, substances are isolated from hair at a significantly lower concentration than alternative methods (e.g., urine or oral fluid), hence hair drug screening emerges as the most challenging methodology to execute.
Affirmation of any positive Screening outcome transpires via GC/MS, GC/MS/MS, or LC/MS/MS. All items suspected positive receive washing prior to affirmation as warranted. The complete laboratory cycle from Accessioning to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 accreditation standards.

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.
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.
