In toxicology it is specifically the highest tested dose or concentration of a substance (i.e. a drug or chemical) or agent (e.g. radiation), at which no such adverse effect is found in exposed test organisms where higher doses or concentrations resulted in an adverse effect. [3] [4] [5]
U.S. Army Public Health Center Toxicology Lab technician assessing samples. Toxicology testing, also known as safety assessment, or toxicity testing, is the process of determining the degree to which a substance of interest negatively impacts the normal biological functions of an organism, given a certain exposure duration, route of exposure, and substance concentration.
Clinical toxicology is the discipline that can be practiced not only by physicians but also other health professionals with a master's degree in clinical toxicology: physician extenders (physician assistants, nurse practitioners), nurses, pharmacists, and allied health professionals. Forensic toxicology is the discipline that makes use of ...
Medical toxicology is a subspecialty of medicine focusing on toxicology and providing the diagnosis, management, and prevention of poisoning and other adverse effects due to medications, occupational and environmental toxicants, and biological agents. [1]
The specific differences between toxicology and medicine/health care cause challenges for implementing EBT. [15] Evidence-based methodology of clinical research has been focused on a single type of study—randomized, controlled clinical trials, which are a direct measure of the effectiveness of the health care intervention under scrutiny.
In some people, administration of penicillin can induce production of specific antibodies and initiate an immune response. Activation of this response when unwarranted can cause severe health concerns and prevent proper immune system functioning. [1] Immune responses to pharmaceutical exposure can be very common in accidental contamination events.
The essentiality of exposure science research extends from the wide range of adverse health outcomes which burden the population. The World Health Organisation predicts that approximately 24% to 40% of the global disease burden is the result of environmental factors, representing the major health burden in developed countries, and indoor smoke from cooking fuels causes 3.8 million deaths every ...
Acute toxicity is distinguished from chronic toxicity, which describes the adverse health effects from repeated exposures, often at lower levels, to a substance over a longer time period (months or years). It is widely considered unethical to use humans as test subjects for acute (or chronic) toxicity research.
