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 ...
Blood compatibility testing is routinely performed before a blood transfusion.The full compatibility testing process involves ABO and RhD (Rh factor) typing; screening for antibodies against other blood group systems; and crossmatching, which involves testing the recipient's blood plasma against the donor's red blood cells as a final check for incompatibility.
In the United States it refers to the fluid portion of one unit of whole blood that has been centrifuged, separated, and frozen solid at −18 °C (0 °F) or colder within eight hours of collection from whole blood donation or was otherwise collected via apheresis device. [9] The phrase "FFP" is often used to mean any transfused plasma product.
An item bank Or Question Bank is a term for a repository of test items that belong to a testing program, as well as all information pertaining to those items. In most applications of testing and assessment, the items are of multiple choice format, but any format can be used.
In medicine, the fluid wave test or fluid thrill test is a test for ascites (free fluid in the peritoneal cavity). It is performed by having the patient (or a colleague) push their hands down on the midline of the abdomen. The examiner then taps one flank, while feeling on the other flank for the tap.
Hypovolemia, also known as volume depletion or volume contraction, is a state of abnormally low extracellular fluid in the body. [1] This may be due to either a loss of both salt and water or a decrease in blood volume. [2] [3] Hypovolemia refers to the loss of extracellular fluid and should not be confused with dehydration.

Interstitial fluid is essentially comparable to plasma. The interstitial fluid and plasma make up about 97% of the ECF, and a small percentage of this is lymph. Interstitial fluid is the body fluid between blood vessels and cells, [8] containing nutrients from capillaries by diffusion and holding waste products discharged by cells due to ...
The lecithin–sphingomyelin ratio is a marker of fetal lung maturity. The outward flow of pulmonary secretions from the fetal lungs into the amniotic fluid maintains the level of lecithin and sphingomyelin equally until 32–33 weeks gestation, when the lecithin concentration begins to increase significantly while sphingomyelin remains nearly the same.
