With cystic tumors, as with simple cysts, LFT results are normal. There may be mild abnormalities in some patients. Carbohydrate antigen (CA) 19-9 levels are elevated in some patients. Cyst fluid can be sent for CA 19-9 testing at the time of surgery as a marker for cystadenoma and cystadenocarcinoma.
