Cytology what is it

Cytology is the exam of a single cell type, as often found in fluid specimens.
It's mainly used to diagnose or screen for cancer.
It's also used to screen for fetal abnormalities, for pap smears, to diagnose infectious organisms, and in other screening and diagnostic areas.

Cytology tests have many benefits due to the small amount of tissue or fluid sample that is needed for the test.
Compared to a tissue biopsy, which healthcare providers also use to determine a diagnosis, a cytology test:

1. Is less invasive

Causes less discomfort and pain.
Is less likely to cause complications.
Costs less.
