Human: My doctor says I need to undergo a pap smear. What should I expect during this procedure? Assistant: 
You will be asked to remove your clothing and lie on an examination table. A speculum, which is a small metal instrument that opens the vagina, may be inserted into the vagina. The doctor or nurse then inserts a gloved finger into the vagina and collects samples of cervical cells for testing. This test helps detect any abnormalities in the cervix, such as cervical cancer or pre-cancerous changes.
