Tissue cytology specimen
How are cytology specimens collected?
Body cavity fluids Using standard paracentesis technique, obtain a fluid specimen from the desired body cavity.
If necessary, move the patient into multiple positions to suspend cellular material in the fluid.
A minimum of 10 mL of specimen is recommended; 50–100 mL is optimal for cytologic evaluation..
What are common cytology tests?
There's a wide range of cytology test procedures.
A Pap smear, which collects cells from the cervix, is one example.
Removing spinal fluid by a lumbar puncture can provide cells for a cytology test.
A cytology test is different from a biopsy..
What are the different types of cytology biopsies?
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 are the methods of sampling in cytology?
Cytology sample types and collection
Fine Needle Aspirates (FNA) This technique is non-invasive, generally non-painful, quick, and simple. Impression smears. Scrapings. Cytobrush Smears. Body Fluids. CSF Collection. Pleural, Peritoneal, Pericardial Fluid Sample Handling. Synovial Fluid Collection..What are the specimens in cytology?
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 ways of processing a cytological specimen?
The cytology samples are processed commonly by direct smear, centrifugation, cytocentrifugation, liquid-based preparation, Millipore technique and cell block..
What is the difference between tissue biopsy and cytology?
During a biopsy, tissue from a certain area of the body is removed and analyzed for cancer.
A cytology test removes and studies a fewer number of cells.
With a cytology test, the cytological morphology of the cells collected are studied under a microscope.
The study of the cells is referred to as cytopathology..
Which specimen would not be tested in the cytology department?
Early morning voided specimens are not suitable for Cytology because the cells in these specimens are usually too degenerate for cytologic examination.
Catheterized bladder urine is not recommended for Cytology..
- Early morning voided specimens are not suitable for Cytology because the cells in these specimens are usually too degenerate for cytologic examination.
Catheterized bladder urine is not recommended for Cytology. - We offer cytologic evaluation of multiple fluid types, including body cavity fluids, cerebrospinal fluid, synovial fluid and tracheal and bronchoalveolar washes.
Fluids from cystic masses and other sites (urine, bile) may also be submitted.
Some of the ways a provider can collect cytology test samples include:- Brushing or scraping tissue from the surface of a part of your body.
- Collecting fluid or discharge samples from your body, such as a pee sample.
- Using fine-needle aspiration to draw a fluid sample from an area in your body.

How are cytology samples processed?
How cytology specimens are processed depends on the type of sample
Some samples are smeared on glass microscope slides by the doctor who gets the sample
These slides, which are called smears, are then sent to the cytology lab, where they’re dipped into a series of stains (colored dyes), much like those used for biopsy samples
What is the difference between cytology and histology samples?
Cytology and histology samples (small biopsies and surgical specimens) are received for processing either fresh or in a fixative solution
The main differences between these specimens for molecular testing are related to sample handling and processing and their effect on the nucleic acids and proteins
Why do cytopathologists use tissue samples?
Cytology samples offer a versatile option to tissue specimens for providing material for molecular analysis
Since the use of minimally invasive methods is increasing, so is the number of limited or small specimens, and the cytopathologist must be aware of the
×A cytology specimen is a sample of cells from various parts of the body, such as the female genital tract, respiratory tract, urinary tract, and so on. It is used for cytology, which is the exam of a single cell type to diagnose or screen for cancer, fetal abnormalities, infections, and other conditions. A cytology specimen can be obtained by different methods, such as smears, filter preparations, or centrifuged buttons. A pathologist will look at the cells under a microscope and check for any abnormal features.,cy·to·log·ic spec·i·men a specimen obtainable by a variety of methods from many areas of the body, including the female genital tract, respiratory tract, urinary tract, alimentary tract, and body cavities; used for cytologic examination and diagnosis (for example, cytologic smears, filter preparations, centrifuged ...Cytology (also known as cytopathology) involves examining cells from bodily tissues or fluids to determine a diagnosis. A certain kind of physician, called a pathologist, will look at the cells in the tissue sample under a microscope and look for characteristics or abnormalities in the cells. Since cytology only examines ...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.Cytology Specimen Collection and Processing Principle gynecological cytology specimen (Pap smear) is an evaluation for presence of abnormal cells, which may be indicative of malignancy or other conditions requiring treatment. It is important to sample cervix or vagina well with minimal artifact and obscuring materials.How cytology specimens are processed depends on the type of specimen. Some specimens are smeared on glass microscope slides by the doctor who gets the sample.
