Fluorescence in situ hybridization
A process in which a small section of fluorescently labeled DNA (a DNA probe) is linked with (hybridized to) the DNA from a chromosome of interest. This technique is used to identify the location of specific genes on chromosomes or areas in which chromosomes have been damaged or duplicated. FISH is used in amniocentesis to…

Fluorescein-dilaurate test
An indirect test of pancreatic function in which fluorescein bound to dilaurate is given orally to a patient and its excretion in the urine is measured. Patients with markedly abnormal pancreatic function fail to excrete the fluorescent tracer in the urine.

Fluorapatite
A compound formed when tooth enamel is treated with appropriate concentrations of the fluoride ion. The modified hydroxyapatite is less acid soluble and therefore resistant to caries. Fluorapatite is formed in bone and in enamel and dentin of teeth when fluoride is taken systemically.

Flumina pilorum
The curved lines along which the hairs of the body are arranged, especially in the fetus.
-
Lung fluke
A fluke that infests lung tissue. Only one species, Paragonimus westermani, is common in humans.
-
Intestinal fluke
One of several species of flukes infesting the intestine in humans. They include Gastrodiscoides hominis, Fasciolopsis buski, Heterophyes heterophyes, and Metagonimus yokogawai.

Risk for imbalance fluid volume
A risk of a decrease, increase, or rapid shift from one to the other of intravascular, interstitial, and/or intracellular fluid. This refers to the loss, gain, or both of body.
-
Risk for deficient fluid volume
At risk for experiencing vascular, cellular, or intracellular dehydration.
-
Excess fluid volume
The state in which an individual experiences increased isotonic fluid retention.
-
Deficient fluid volume
Decreased intravascular, interstitial and/or intracellular fluid. This refers to dehydration, water loss alone without change in sodium.
