transudate

 [tran´su-dāt]
a fluid substance that has passed through a membrane or has been extruded from a tissue; in contrast to an exudate, a transudate is characterized by high fluidity and a low content of protein, cells, or solid matter derived from cells.

tran·su·date

(tranz'yū-dāt),
Any fluid (solvent and solute) that has passed through a presumably normal membrane, such as the capillary wall, as a result of imbalanced hydrostatic and osmotic forces; characteristically low in protein unless there has been secondary concentration. Compare: exudate.
Synonym(s): transudation (2)
[trans- + L. sudo, pp. -atus, to sweat]

transudate

1. A fluid that has passed through a membrane.
2. A collection of fluid resulting from increased capillary pressure in capillary beds or decreased osmosis from reduced blood protein.

transudate

any substance that passes through a membrane, especially through the wall of a capillary

Transudate

The type of pleural effusion seen with heart failure or other disorders of the circulation. It features clear fluid containing few cells and little protein.
