Cytology is most often used to diagnose the nature of 'lumps and bumps' found on the surface of the body. However, cytology can also be used to evaluate: internal organs, such as the liver, lungs, lymph nodes, and kidneys. body fluids, such as joint fluid.
Cytology is a non-invasive diagnostic tool: Cytology investigates animal or human cells from tissues or fluids. Fine-needle aspirates, impression smears, or fluid analysis can be evaluated. It is a relatively non-invasive procedure compared to other diagnostic methods.
How Are Cells collected?
There are several different methods for collecting cells from tissues, depending on where the problem is and what type of tissue is involved.
The most common technique is called fine needle aspiration (FNA).
This simple technique involves using a sterile, fine gauge needle attached to an empty syringe.
The needle is inserted into the middle of the .

How Does This Information Help My Veterinarian Manage A Problem?
If the problem is inflammatory in nature, your veterinarian can take steps to look for a specific cause (bacteria, parasite, fungus, allergies, foreign bodies, etc.) in order to provide the appropriate treatment.
If cytology indicates neoplasia, the appearance of the cells can often indicate the type of tumor and predict how it will behave.
This is.

What Are The Limitations of Cytology?
The main limitation of cytology is that the cells collected may not tell the whole story about what is happening in the tissue.
This may happen if samples are very small, or if the most diagnostic (or representative) cells are not present in the sample.
In addition, some tumors do not play by the rules: sometimes the cells may look benign, but the .

What Information Can Cytology provide?
The most important thing cytology can tell us is whether a problem is caused by inflammation or by neoplasia (abnormal growth of tissue).
If there is inflammation, cytology can often identify the underlying cause.
If the sample appears to be neoplastic, cytology can usually determine which type of tissue is involved and whether the neoplasm is mali.

What Is Cytology?
Cytology is the microscopic examination of cells that have been collected from the body.
By examining the appearance of these cells, including their number, size, shape, color, internal characteristics, and how they fit together with their neighbors, it is often possible to make a diagnosis of a specific disease process.

What is morphology cytology?
Morphology - Cell, Structure, Function:
- The living material of most organisms is organized into discrete units called cells
- the study of their features is known as cytology

What is veterinary cytology?
The first two sections of Veterinary Cytology focus on cytology techniques, quality control, and special laboratory techniques.
Subsequent sections are organ/tissue-based and reflect what is known about the canine, feline, and equine species.

When Is Cytology Performed?
Cytology is most often used to diagnose the nature of 'lumps and bumps' found on the surface of the body.
However, cytology can also be used to evaluate: 1. internal organs, such as the liver, lungs, lymph nodes, and kidneys 2. body fluids, such as joint fluid 3. abnormal accumulations of fluids (called effusions), especially in the chest and abdom.
