What does liquid-based cytology test for?
However, liquid-based cytology rinses cervical cells in preservatives so that blood and other potentially obscuring material can be separated. It also allows for additional testing of the sample, such as for human papillomavirus (HPV).
What is liquid-based cytology technique?
Liquid-based cytology is a technique that enables cells to be suspended in liquid medium and spread in monolayer and thus better morphological assessment is possible. It includes the preparation and evaluation of cells collected in a liquid fixative.
Why is liquid-based cytology better?
Liquid-based cytology (LBC) has advantages of fewer unsatisfactory smears, faster and more efficient method, more accurate interpretation, less obscuring materials such as blood, mucous, inflammatory cells in smears and the use of residual cell suspension for testing human papillomavirus (HPV) DNA and …
How do you take liquid-based cytology?
LBC is a new method of cervical cell sample preparation. Samples are collected in the usual way, but using a brush-like device rather than a spatula. The head of the device is rinsed or broken off into a vial of preservative fluid so that most or all of the cervical cells are retained.
What are cytology results?
The test helps identify and diagnose cancerous and noncancerous cells. Test results may also help classify the disease. If something is detected on a screening cytology test that requires further information, your doctor may order more tests, such as a repeat cytology or a biopsy.

How is cervical cytology performed?
The method consists of sampling cells from the cervix. A doctor or nurse inserts an instrument (a speculum) to open the woman’s vagina so that they can see the cervix. The sample of cells from the surface of the cervix is obtained using a small brush.
Is cytology the same as Pap smear?
Cervical cancer screening is used to find changes in the cells of the cervix that could lead to cancer. Screening includes cervical cytology (also called the Pap test or Pap smear), testing for human papillomavirus (HPV), or both. Most women should have cervical cancer screening on a regular basis.
What is liquid base pap smear?
In a liquid-based Pap test, the cells are rinsed into a small container of liquid. The cells are then placed onto slides by a special machine and examined under a microscope to see if the cells are abnormal.
How do you screen for HPV?
During an HPV test, your doctor or nurse puts a metal or plastic speculum into your vagina. The speculum is opened to separate the walls of your vagina so that they can see your cervix. Your doctor or nurse then uses a small sampler — a tiny spatula or brush — to gently take a small number of cells from your cervix.
