Edema (American English), also spelled oedema (British English), and also known as fluid retention, dropsy and hydropsy, is the build-up of fluid in the body's tissue, [1] a type of swelling. [4] Most commonly, the legs or arms are affected. [ 1 ]
If the drop retains its shape, stays attached to the surface or slowly floats down to the bottom of the tube (drop- or jelly-fish-like), the Rivalta's test is defined as positive. The Rivalta's test had a high positive predictive value (86%) and a very high negative predictive value for FIP (96%) in a study in which cats that presented with ...
Fluid retention can be a symptom of underlying conditions such as kidney disease, heart failure and liver disease, says Badgett. Certain cancers and cancer treatments can cause edema. “Sometimes ...
Water retention can refer to: Water retention (medicine), an abnormal accumulation of fluid in the circulatory system or within the tissues or cavities of the body Edema, an abnormal accumulation of fluid beneath the skin, or in one or more cavities of the body; Premenstrual water retention, a common phenomenon associated with the menstrual cycle
Fluid balance is an aspect of the homeostasis of organisms in which the amount of water in the organism needs to be controlled, via osmoregulation and behavior, such that the concentrations of electrolytes (salts in solution) in the various body fluids are kept within healthy ranges.
A fluid or water deprivation test is a medical test [1] which can be used to determine whether the patient has diabetes insipidus as opposed to other causes of polydipsia (a condition of excessive thirst that causes an excessive intake of water). The patient is required, for a prolonged period, to forgo intake of water completely, to determine ...
The false positive rate (FPR) is the proportion of all negatives that still yield positive test outcomes, i.e., the conditional probability of a positive test result given an event that was not present. The false positive rate is equal to the significance level. The specificity of the test is equal to 1 minus the false positive rate.
Water retention curve is the relationship between the water content, θ, and the soil water potential, ψ. The soil moisture curve is characteristic for different types of soil, and is also called the soil moisture characteristic. It is used to predict the soil water storage, water supply to the plants (field capacity) and soil aggregate stability.
