Is a Pap smear safe when you're pregnant? Pap smears aren't just safe during pregnancy, they're actually a routine part of prenatal care. Your doctor will need to know if you're at risk for cervical cancer and will check to see if you have any STDs, which can cause premature births or even blindness. You'll probably have a Pap at your first pregnancy checkup.
The Pap test is generally used as a screening test. A certain percentage of abnormalities in women may go undetected with a single Pap test, which is why it is important to have Pap test done regularly. A significant limitation of the test has to do with sample collection. The Pap test represents a very small sample of cells present on the cervix and in the vaginal area. Even for the most experienced health practitioner, sample collection can be occasionally inadequate and a repeat Pap may be required.
