Pleural fluid analysis (cell differential and chemistry) results.

Investigation	Result	Reference range
WBC∗	225/uL	<1000/uL
RBC	200/uL	0–10,000/uL
LDH	111 U/L	<200 U/L
pH	7.54	7.60–7.66
Protein†	61 g/L	<25 g/L
Glucose	16.3 mmol/L	4.0–5.4 mmol/L

LDH = lactate dehydrogenase, RBC = red blood cells, WBC = white blood cells.

^∗Lymphocyte predominance 89%, neutrophils 5%, eosinophils 3%, and mesothelial cells 3%.

^†High protein suggestive of exudative pleural effusion.
