Transudate

As a transudate emerging non-inflammatory body fluids are known in medicine by passing epithelia and from vessels. The process of separation of such liquids is called transudation. A distinction they are of the inflammatory conditions exudates. Transudates occur in healthy and pathological bodily processes.

Properties

Transudates are relatively poor in cells and usually contain only desquamated mesothelial cells and a few leukocytes. The protein content is small and is usually less than 30 g / L. The specific gravity is less than 1.012. Transudates are usually clear, possibly with a light yellow color.

Physiological transudates

Physiologically occur transudates than exudates of epithelia. Here they form a fine film of liquid, so it is only small amounts of liquid. Such transudates are for example the vaginal or the liquid film on the serosa.

Pathological transudates

Possible causes pathological transudates are:

• Too little water-binding capacity of the blood due to a lack of blood proteins ( albumin ) and thus decreasing colloid osmotic pressure.
• Congestion and associated increase in pressure in the blood stream or the lymphatics

The transudates can as effusion ( hydrops, ascites, pleural effusion) in a body cavity or as edema, ie, an accumulation of fluid in the interstitium occur.
