Proteins leak out; capillaries opened up

Malignancy, pneumonia, TB (most common cause of pleural effusion worldwide)

3

Imaging

A

Lateral decubitus position

Q

Light’s criteria

A

LDHf (fluid comes first)
LDHf/LDHs (fluid/serum)
TPf/ TPs (total protein)

A ratio closer to 1 indicates that it is exudate (fluid contains more protein)

ALL HAVE TO BE NEGATIVE FOR IT TO BE A TRANSUDATE

5
