In Crowell, Texas, Accredited Drug Testing provides comprehensive hair follicle drug assessments. If you're seeking a hair drug or alcohol evaluation, Accredited Drug Testing excels in this area, with locations across every city nationwide capable of conducting a hair analysis. Typically, a sample length of 1.5 to 2 inches from the crown or body is needed. Hair tests can detect drugs, alcohol/ETG, or be customized for specific analyses.
Nowadays, hair follicle tests are increasingly common for substance screening. Employers, judicial systems, and substance abuse counselors often prefer hair tests to urine tests. This method supports strict drug-free policies, legal requirements, and probation compliance. Its primary advantage is an extended detection period of up to 90 days, ensured by a closely supervised collection that is hard to manipulate. Nevertheless, urine tests remain the best for identifying recent usage within five days.

Hair testing has garnered recognition as an effective method for detecting the use of drugs and alcohol. Within the growing hair strand, biomarkers get trapped, providing a long-term record of drug and alcohol use. When taken near the scalp, a hair sample can reveal alcohol and drug presence for a period of up to about three months. Collecting hair is straightforward, relatively difficult to tamper with, and convenient for shipping.
Securing a sample of approximately 1.5 inches and about 200 strands (comparable in size to a #2 pencil) nearest to the scalp will supply 100mg of hair, which is ideal for both screening and confirmation. For EtG, additional tests, and/or analyses beyond 10 panels, it is advisable to gather 150mg of the hair sample. We advise using a jeweler's scale to measure the specimen weight. In the absence of scalp hair, a similar amount of body hair can be taken. Life when we mention head hair, we mean scalp hair specifically. Body hair encompasses all other types of hair (facial, axillary, etc.).
Process Overview
The fundamental steps in lab processing of drug test results consist of Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the primary processing of a specimen into the lab's system, ensuring proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any missing data entry that electronic methods didn’t cover.
Screening performs an initial fast assessment for drug abuse. Although it offers a cost-effective method to exclude drug use in many specimens, confirmation is imperative for court admissibility of positive screens. Samples indicated as presumptively positive in Screening must undergo secondary confirmation.
In cases where samples appear positive during Screening, additional hair is extracted from the original sample for preparation during Extraction. Drugs are retrieved from hair in this stage at significantly reduced concentrations compared to other techniques (e.g., urine or oral fluid), contributing to the complexity of hair drug screening.
GC/MS, GC/MS/MS, or LC/MS/MS methods validate any positive screening outcomes. Presumptive positive samples undergo necessary washing before confirmation. The complete lab process, spanning from Accessioning to Confirmation, adheres to both CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Although often termed "hair follicle tests", the procedure examines the hair strands, not the follicle located under 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.
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.
