What is poison test? Definition & meaning

Poison is a substance that, when ingested, inhaled, or otherwise absorbed, can cause harm, illness, or death to living organisms. It typically contains toxic compounds that disrupt the normal functioning of the body’s systems. Poison can be found in various forms, including liquids, gases, solids, or even as microscopic particles. Some common examples of poisonous substances include certain chemicals, plants, venom from animals, and even some medications if used improperly. Poisonous effects can vary widely, ranging from mild discomfort to severe symptoms such as organ failure or paralysis. Due to its dangerous nature, caution must be exercised when handling or dealing with poisonous substances to prevent harm to oneself or others.

A test is a systematic procedure or examination performed to assess someone’s knowledge, skills, abilities, or the quality, functionality, or characteristics of a particular object, substance, or system. Tests are used in various fields, such as education, healthcare, psychology, and quality control. They are designed to measure or evaluate performance, understanding, aptitude, proficiency, or the presence of specific traits or conditions. Tests can take different forms, including written exams, practical demonstrations, interviews, physical evaluations, or scientific experiments. The results of a test are often used to make informed decisions, such as determining academic grades, diagnosing medical conditions, selecting candidates for a job, or validating the effectiveness of a product or process. Tests play a crucial role in gathering data, making assessments, and facilitating decision-making processes in a wide range of contexts.

Quality refers to the degree of excellence or superiority of something, indicating its ability to meet or exceed expectations, standards, or specifications.
