Editing Pap test (section)

===Practical aspects===
The endocervix may be partially sampled with the device used to obtain the ectocervical sample, but due to the anatomy of this area, consistent and reliable sampling cannot be guaranteed. Since abnormal endocervical cells may be sampled, those examining them are taught to recognize them.{{citation needed|date=November 2022}}

The endometrium is not directly sampled with the device used to sample the ectocervix. Cells may exfoliate onto the cervix and be collected from there, so as with endocervical cells, abnormal cells can be recognised if present but the Pap test should not be used as a screening tool for endometrial malignancy.{{citation needed|date=November 2022}}

In the United States, a Pap test itself costs $20 to $30, but the costs for Pap test visits can cost over $1,000, largely because additional tests are added that may or may not be necessary.<ref>{{cite journal | author = Bettigole C | title = The Thousand-Dollar Pap Smear | journal = New England Journal of Medicine | volume = 369 | issue = 16 | pages = 1486–1487 | year = 2013 | pmid = 24131176 | doi = 10.1056/NEJMp1307295 }}</ref>
