The Test Sample
|
| |
What is being tested?A Pap smear is a test used to detect abnormal or potentially abnormal cells from the vagina and uterine cervix. Various bacterial, fungal, and viral infections of the uterus may also be detected using this test.
How is the sample collected for testing?
The conventional method consists of sampling cells from the cervical area. The sample is obtained using a type of wooden “spatula,” cotton swab, or brush. Relatively new liquid-based methods are available that are modifications of the conventional Pap smear. The specimen is collected as noted above, but is not “smeared” onto a glass slide. Rather, it is put into a special liquid preservative. This cell suspension is processed onto a glass slide, stained, and examined.
NOTE: If undergoing medical tests makes you or someone you care for anxious, embarrassed, or even difficult to manage, you might consider reading one or more of the following articles: Coping with Test Pain, Discomfort, and Anxiety, Tips on Blood Testing, Tips to Help Children through Their Medical Tests, and Tips to Help the Elderly through Their Medical Tests.
Another article, Follow That Sample, provides a glimpse at the collection and processing of a blood sample and throat culture.
Is any test preparation needed to ensure the quality of the sample?
You may be instructed not to douche or tub bathe during the 24 hours before the Pap smear is to be performed. You may also be asked to refrain from sexual intercourse for 24 to 48 hours before the test.
