Sometimes the appendix is “white”.
A diagnosis of acute appendicitis is made on clinical grounds. That means that the surgeon takes a history and examines the patient and comes to a diagnosis of acute appendicitis. Investigations (tests) are additional procedures that are used to rule out other diagnoses, that is to make sure that the cause of the pain is not something else, eg. urinary stone or infection, ovarian cyst, ectopic pregnancy, etc. Or to assist to make a diagnosis when there is doubt. The treatment for acute appendicitis is appendicectomy (removal of the appendix).

A “white” appendix
Occasionally, another explanation for the pain may be found during the operation. The appendix is actually not inflammed (not appendicitis). We call it “white” (as opposed to a “red” inflammed appendix.) A common cause of pain in the right lower quarter of the abdomen, which mimics appendicitis, is a ruptured right ovarian cyst. The blood and fluid from the cyst causes pain similar to appendicitis.

An cyst on the right ovary.
So there’s the answer.
