How do you perform a cytological smear?
- Using a pencil, label the frosted end of a microscope slide with the patient’s name.
- Remove cells from the oral mucosa with a Cytobrush or tongue blade and spread them evenly on the microscope slide.
- Repeat procedure on a second microscope slide.
- Spray the slides lightly with a fixative.
What is a cytology test for?
Cytology is the exam of a single cell type, as often found in fluid specimens. It’s mainly used to diagnose or screen for cancer. It’s also used to screen for fetal abnormalities, for pap smears, to diagnose infectious organisms, and in other screening and diagnostic areas.
What is cytological technique?
Cytological techniques are methods used in the study or manipulation of cells. These include methods used in cell biology to culture, track, phenotype, sort and screen cells in populations or tissues, and molecular methods to understand cellular function.
What is a cytological specimen?
Cytology: A specimen is ordered as a “cytology” when no core biopsy has been obtained. This is when the aspirate is used to make cytology smears and placed in the cytojar ONLY. Examples of cytology specimens include fine needle aspirations of thyroid, pancreas, cysts etc.
What are the two types of cytology?
There are two main kinds, or branches, of cytology: exfoliative cytology and intervention cytology. Healthcare providers can use cytology tests for almost all areas of your body. Some common types of cytology tests include: Gynecologic cytology.
What is an example of cytology?
For example, a common example of diagnostic cytology is the evaluation of cervical smears (referred to as the Papanicolaou test or Pap smear). In order for cytologic evaluation to be carried out, the material to be examined is spread onto glass slides and stained.
How accurate are cytology test?
Many studies have evaluated the accuracy of urine cytology in the detection of bladder cancer. Overall, the reported sensitivity ranges from 20% to 97.3%; specificity ranges from 74% to 99.5%.
What is the most important tools of cytology?
The most famous ones are FNA, fine needle aspiration biopsy (FNAB), and needle aspiration biopsy cytology (NABC). All of them mean the same thing; aspirating cellular material using a fine needle to make a diagnosis.
What is difference between cytology and cytopathology?
Cytology is the study of individual cells and cytopathology is the study of individual cells in disease. Sampled fluid/ tissue from a patient is smeared onto a slide and stained (see techniques).
What is cytopathology used for?
Diagnosing diseases by looking at single cells and small clusters of cells is called cytology or cytopathology. It’s an important part of diagnosing some types of cancer.
