What causes transudate vs exudate?
“Transudate” is fluid buildup caused by systemic conditions that alter the pressure in blood vessels, causing fluid to leave the vascular system. “Exudate” is fluid buildup caused by tissue leakage due to inflammation or local cellular damage.

Which is worse transudate or exudate?
Exudates typically have higher protein concentration and LD activity and lower pH and glucose values than transudates. The protein concentration of an exudate usually exceeds 3 g/dL. Exudate LD activity is greater than 0.67 times the upper limit of normal for serum.
What is the most common cause of a transudate?
Transudates: Overwhelming the System The most common cause of a transudate is CHF. The increased pulmonary capillary hydrostatic pressure in patients with CHF results in a net flow of fluid into the pulmonary interstitium. This fluid readily moves across the leaky visceral pleura into the pleural space.
What is the cause of exudate?
Common causes of exudates include pulmonary infections like pneumonia or tuberculosis, malignancy, inflammatory disorders like pancreatitis, lupus, rheumatoid arthritis, post-cardiac injury syndrome, chylothorax (due to lymphatic obstruction), hemothorax (blood in pleural space) and benign asbestos pleural effusion.
What are the causes of transudate?
Transudative pleural effusion is caused by fluid leaking into the pleural space. This is from increased pressure in the blood vessels or a low blood protein count. Heart failure is the most common cause.

Does pleural effusion cause pain?
Patients with pleural effusion may experience sharp pains in the chest, shortness of breath, and coughing. Symptoms of pleural effusion tend to subside when the underlying condition is treated.
What is difference between exudate and transudate?
Exudates are fluids, CELLS, or other cellular substances that are slowly discharged from BLOOD VESSELS usually from inflamed tissues. Transudates are fluids that pass through a membrane or squeeze through tissue or into the EXTRACELLULAR SPACE of TISSUES.

What is the difference between transudative and exudative ascites?
Transudative ascites occurs when a patient’s SAAG level is greater than or equal to 1.1 g/dL (portal hypertension). Exudative ascites occurs when patients have SAAG levels lower than 1.1 g/dL. (See the Ascites Albumin Gradient calculator.)
What is the most common cause of transudative pleural effusion?
There are two types of pleural effusion: Transudative pleural effusion is caused by fluid leaking into the pleural space. This is from increased pressure in the blood vessels or a low blood protein count. Heart failure is the most common cause.
What is transudate vs exudate pleural effusion?
Key Points. Transudative effusions are caused by some combination of increased hydrostatic pressure and decreased plasma oncotic pressure. Exudative effusions result from increased capillary permeability, leading to leakage of protein, cells, and other serum constituents.
What is the difference between transudative and exudative fluid?
Why is SAAG high in portal hypertension?
The increase in hydrostatic pressure causes more fluid to leave the circulation into the peritoneal space (ascites). The SAAG subsequently increases because there is more free fluid leaving the circulation, concentrating the serum albumin.
