Drug testing is a method used to detect the presence of drugs or their metabolites in biological samples, typically to ensure compliance with legal, workplace, or athletic standards. It involves various techniques and technologies that differ in sensitivity, specificity, and the types of substances they can detect.

Biological samples are critical for understanding and analyzing the biological processes of organisms, enabling advancements in fields such as medicine, genetics, and environmental science. These samples, which include tissues, cells, blood, and other bodily fluids, must be collected, stored, and processed under specific conditions to maintain their integrity and reliability for research and diagnostic purposes.

Compliance refers to the adherence to laws, regulations, guidelines, and specifications relevant to an organization's business processes. It ensures that organizations operate within legal frameworks and ethical boundaries, thereby minimizing risks and enhancing trust with stakeholders.

compliance

Legal standards are established criteria within the legal system that guide the behavior of individuals and organizations, ensuring fairness, consistency, and justice. They serve as benchmarks for legal decisions and are often derived from statutes, regulations, and case law, influencing the interpretation and application of the law.

Legal Standards

Workplace standards are essential guidelines that ensure a safe, equitable, and productive environment for all employees. They encompass legal requirements, ethical practices, and organizational policies aimed at fostering respect, safety, and efficiency in the workplace.

Sensitivity refers to the ability of a system or individual to detect or respond to subtle changes, signals, or stimuli in their environment. It is a critical parameter in fields like medicine, psychology, and engineering, where it influences diagnostics, perception, and system performance.

sensitivity

Specificity refers to the ability of a test to correctly identify those without the condition, minimizing false positives. It is a crucial metric in diagnostics, ensuring that healthy individuals are not misclassified as having a disease.

types of substances

Metabolites are small molecules that are intermediates and products of metabolism, playing critical roles in various biological processes. They are essential for growth, development, and homeostasis in living organisms, and their study is crucial for understanding disease mechanisms and developing therapeutic strategies.
