Is immunohistochemistry a cytology?
Conclusions: Immunochemistry can be used to increase the predictability of a cytology diagnosis if care is taken with the cytology sample preparation methodology and there is judicious use of select monoclonal antibody panels to support a specific cytology diagnosis.
How cytology smear was done?
In cytological smear, the sample is either smeared on a glass slide or made on a monolaye, and it is subsequently stained with the following stains- Papanicolaou, Diff quick and heamatoxylin and eosin. Samples of CB are fixed in 10% neutral buffered formalin and then treated as a tissue block.

What is meant by immunohistochemistry?
Immunohistochemistry (IHC) is the most common application of immunostaining. It involves the process of selectively identifying antigens (proteins) in cells of a tissue section by exploiting the principle of antibodies binding specifically to antigens in biological tissues.
What is the difference between histology and immunohistochemistry?
is that histopathology is (biology) the microscopic study of tissue, especially of abnormal tissue as a result of disease while immunohistochemistry is (biology|chemistry) the analytical process of finding proteins in cells of a tissue microtome section exploiting the principle of antibodies binding specifically to …
Why do you get Pap smears?
A Pap smear is used to screen women for cervical cancer. Years ago, women had a Pap smear at each annual visit, but today Pap smears have improved and we know cervical cancer takes many years to develop. Women should start Pap smear screening at age 21.
Is cytology a Pap smear?
For many years, cytology-based screening, known as the Pap test or Pap smear, was the only method of screening. Its use reduced cervical cancer incidence and deaths in countries where screening is common.
