Q

How do we differentiate between transudate and exudate fluid in a pleural effusion?

A

Exudate have a protein of >30g/L, transudates have a protein of <30g/L
If protein is between 25-35g/L consider the Light’s criteria (exudate if):

Pleural:Serum LDH >0.6
Pleural fluid LDH is more than 2/3rd the upper limit of normal serum LDH
