Transudate

A transudate is a collection of fluid that has a relatively low specific gravity and protein concentration. They occur secondary to increased hydrostatic pressure or reduced colloid oncotic pressure:

• left ventricular failure (increased hydrostatic pressure)
• hypoalbuminemia (decreased colloid oncotic pressure)
  • ​cirrhosis
  • nephrotic syndrome (proteinuria)
