In Driscoll, Texas, Accredited Drug Testing offers comprehensive hair follicle drug assessments. For hair drug or alcohol analysis, Accredited Drug Testing focuses on hair evaluation and features testing sites nationally capable of conducting these tests. Generally, 1.5 to 2 inches of head or body hair suffices. Hair examinations can identify drug use, alcohol/ETG, or other bespoke hair evaluations.
In recent times, drug testing trends have increasingly shifted toward hair follicle analysis. Numerous employers, judicial systems, and substance abuse experts now favor hair drug tests over typical urine tests. These are preferred by organizations with strict drug policies, courts, and probationary programs. The key advantage is the extended detection potential for drug use, usually up to 90 days, with observation collections nearly impervious to tampering. Nevertheless, for detecting recent drug usage within the last five days, urine tests remain exceptionally accurate.

Hair analysis is recognized as an effective method for identifying the usage of drugs and alcohol. Hair captures extended records of these substances by holding biomarkers within the fibers as the hair grows. Acquiring samples near the scalp can offer a detection period of roughly 3 months for various drugs and alcohol. The process of gathering hair samples is straightforward, difficult to tamper with, and simple to transport.
A 1.5-inch segment consisting of around 200 hair strands (similar in thickness to a #2 pencil) closest to the scalp will yield 100mg, which is the optimal sample size for both screening and confirmation tests. For EtG, additional tests, or tests exceeding 10 panels, a sample weight of 150mg is advised. We suggest using a jeweler’s scale for accurate measurement. If head hair is inaccessible, an equivalent amount of body hair can be used. "Head hair" specifically refers to scalp hair, while "body hair" includes all other hair forms (facial, axillary, etc.).
Process Overview
The procedure for processing a drug test result in the lab includes four principal stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into the laboratory framework. This process guarantees the sample's seal and shipment integrity, assigns a random LAN (Laboratory Accessioning Number), and completes any outstanding data entry not covered by an electronic chain of custody.
Screening provides an initial rapid check for drugs of abuse. Though Screening is an economical method to exclude drug use for most samples, a positive outcome must be validated for legal admissibility. Samples that appear positive during Screening necessitate further verification.
For samples indicated as positive in Screening, additional hair is extracted from the starting sample to undergo Extraction. In this phase, drugs are separated from the hair at much lower concentrations than in methods like urine or oral fluids, highlighting the challenge in hair drug screening.
Positive screening results undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS methods. Any samples presumed positive are cleansed before confirmation as necessary. The full lab process, from Accessioning to Confirmation, is evaluated following both the CAP (College of American Pathologists) Hair standards and the ISO / IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: Although commonly called "hair follicle tests", the test examines the hair strand and does not involve the follicle beneath 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.

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.
