hi @nbmehelp. if you are confused about a comment or unhappy with an explanation, please pose a specific question so we can help answer or clarify. thanks!
But malignancy effusion also has glucose < 60 mg/dL so I was between that and increased protein. My reasoning was that cancer cells have high metabolic rate so they require increased energy/glucose
I thought the same thing @rthavranek , all exudative effusions should have increased protein. That being said, still picked decreased glucose

Pt has malignant effusion, which you would expect to be exudative. Exudative is characterized by protein pleural/serum > 0.5 LDH pleural/serum >0.6, and a LDH >2/3 upper limit of normal. So that would be increased protein or increased LDH, LDH is not an answer, so easy to rule out.
