A cytology exam of urine is a test used to detect cancer and inflammatory diseases of the urinary tract.
Alternative NamesUrine cytology
How the test is performedA clean catch (midstream) urine sample is needed. For information on how to obtain the sample, see clean catch urine specimen.
The urine sample can also be collected during an examination of the inside of your bladder called cystoscopy.
The urine sample is processed in a laboratory and examined under a microscope to look for abnormal cells.
How to prepare for the testNo special preparation is needed.
How the test will feelThere is no discomfort with a clean catch urine specimen.
Why the test is performedThe test is done to detect cancer of the urinary tract. It is often done when blood is seen in the urine.
It is also useful for monitoring patients who have a history of urinary tract cancer. The test may sometimes be ordered for people who are at high risk for bladder cancer.
This test can also detect cytomegalovirus and other viral diseases.
Normal ValuesThe urine shows normal cells and is free of debris.
Note: Normal value ranges may vary slightly among different laboratories. Some labs use different measurements or test different samples. Talk to your doctor about the meaning of your specific test results.
What abnormal results meanAbnormal cells in the urine may be a sign of inflammation of the urinary tract or cancer of the kidney, ureters, bladder, or urethra.
Special considerationsCancer or inflammatory disease cannot be diagnosed with this test alone. The results need to be confirmed with other tests or procedures.
A technique called fluorescent in situ hybridization (FISH) can be used to test the genetic material in cells shed in the urine to better detect cancers.

What are the three basic parts of the typical urine examination?
The three basic parts of a typical urine examination are physical examination (color, clarity, odor), chemical examination (testing for specific compounds like glucose, protein, and ketones), and microscopic examination (analyzing urine sediments for cells, crystals, and other particles).
How is PXE determined?
The presence of calcium in elastic fibers, as revealed by microscopic examination of biopsied skin, unequivocally establishes the diagnosis of PXE.
What is meant by pus cells in microscopic examination of centrifuged deposit during routine urine examination?
pus cells in microscopic examination means urinary tract infection (UTI). upto 5 pus cells are normal. above 5 cells indicates moderate to severe infection. take advise of ur physician or uro surgeon. ashish rastogi
What is a tissue sample for microscopic examination called?
It is a biopsy
Why must urine be centrifuge for microscopic?
Urine must be centrifuged before microscopic examination to separate any cells, bacteria, and other solid components from the liquid portion, or supernatant. This allows for a clearer view of the cells and other elements present in the urine sample under a microscope, making it easier to detect abnormalities or infections.
What is the preferred urine specimen for microscopic examination of urine sediment?
Using a standardized Urinalysis System
What is urinaltsis?
urinalysis: or UA is a physical, chemical, and microscopic examination of urine.
What can be revealed by microscopic examination of bone marrow?
Microscopic examination of bone marrow can reveal leukemia, granulomas, myelofibrosis, myeloma, lymphoma, or metastatic cancers, bone marrow infection, and bone disease.

Is the microscopic examination of urine sediment would fall under waived testing true?
true
How is PXE determined?
The presence of calcium in elastic fibers, as revealed by microscopic examination of biopsied skin, unequivocally establishes the diagnosis of PXE.
What is a normal urinalysis?
A normal urinalysis typically includes clear urine with a pale yellow color, a specific gravity within a normal range, no presence of blood, protein, glucose, or ketones, and a pH level around 4.5 to 8.0. It also usually has no bacteria, crystals, or abnormal cells present.
What the difference between gross and microscopic examination?
Gross examination is performed without the aid of magnification. Microscopic examination is performed on slides of tissue samples on the microscope.
What is urine R and M mean?
Urine R and M stands for Urine Routine and Microscopic examination. It is a laboratory test that involves chemical, physical, and microscopic analysis of a urine sample to check for various substances such as proteins, glucose, red and white blood cells, and bacteria. This test is commonly used to diagnose urinary tract infections, kidney disease, and other urinary system-related conditions.
What is urine FEME?
Ah, urine FEME stands for urine full examination. It's a simple test where the doctor checks your urine for things like blood cells, protein, sugar, and bacteria to see if everything is healthy and working well inside your body. It's just a way for your doctor to make sure you're feeling your best, like painting a beautiful landscape to make sure all the colors are just right.
What is the the microscopic structure of the functional unit of the kidney and the of urine production?
The microscopic, functional unit of the kidney and the site of urine-production is the Nephron.
What are three parts of a routine urinalysis?
Three parts of a routine urinalysis include physical examination (color, clarity, odor), chemical examination (pH, protein, glucose), and microscopic examination (red blood cells, white blood cells, bacteria).
