Label specimen cup with patient’s name and today’s (specimen collection) date. 4. Fill specimen cup ¾ full with second voided urine. 5. Screw on specimen cup lid tightly.
How do you collect a urine specimen?
During the procedure. A urine cytology test requires a urine sample, which you provide by urinating into a sterile container. In some cases, a urine sample is collected using a thin, hollow tube (catheter) that's inserted into your urethra and moved up to your bladder.
How do you do a urine cytology test?
Urine cytology is a more specific test that involves looking at cells in a sample of urine under a microscope. A pathologist most commonly looks for cancer cells specifically. A urinalysis is a urine screening test.
What is the difference between a urinalysis and cytology?
Fill specimen cup ¾ full with second voided urine. 5. Screw on specimen cup lid tightly. 6. Complete Cytology Request Form.
How to fill specimen cup with second voided urine?
What are the 4 methods of collecting a urine sample?
Diagnosis requires collection of urine generally by 1 of 4 methods: sterile urine bag, urethral catheterization (CATH), suprapubic aspiration (SPA), or clean-catch (CC).
What is procedure for cytology test?
The most common type of intervention cytology is fine-needle aspiration (FNA). A healthcare provider will inject a thin needle into the area that they need to sample and draw out fluid. A pathologist then examines the cells in the fluid under a microscope.
How much urine is needed for urine cytology?
Although 10 mL of fresh voided urine might achieve sufficient cellularity, higher volume (≥30 mL) is recommended in order to maximize the chance of detecting a high-risk diagnosis. Nevertheless, the presence of high-grade urothelial carcinoma can still be detected in low-volume (<20 mL) specimens.
What are the 3 methods of retrieving a urine sample?
For a urinalysis, your urine sample is evaluated in three ways: visual exam, dipstick test and microscopic exam.
How accurate is urine cytology?
The accuracy of urine cytology depends on several factors that are mainly related to tumor grade, the nature of specimen, and sampling. It has long been known that urine cytology is accurate in the diagnosis of high-grade urothelial carcinoma (HGUCA) with cytohistologic correlation reported as high as 98%.
What is the difference between urinalysis and urine cytology?
Urinalysis can help find some bladder cancers early, but it has not been shown to be useful as a routine screening test. Urine cytology: In this test, a microscope is used to look for cancer cells in urine. Urine cytology does find some cancers, but it's not reliable enough to make a good screening test.
What is the best time of day to collect a urine sample for cytology?
Collection should be approximately 3 hours after first urine or second urine of the day.
What cancers can be detected in urine?
Bladder cancer is perhaps the most obvious cancer to find in urine, but evidence suggests that remnants of other cancers – like kidney, prostate and cervical cancer – can also get into pee.
Why is urine cytology done?
Urine cytology is a test to screen a patient's urine for cancer cells. This is one of many tools used to diagnose cancers in the urinary tract, including bladder, kidney, prostate, ureter and urethra cancers. A urine cytology test alone can't diagnose cancer.
What is the most commonly used method to collect urine samples?
Traditionally, a research team, clinician or lab will issue a specimen cup that a person uses to self-collect their midstream urine. This involves placing the specimen cup under the stream of urine to catch a sample as instructed.
When is the best time to do a urine sample?
You can collect a urine sample at any time of day, unless your GP or practice nurse advises you otherwise. The types of urine sample you might be asked for include a random specimen, first morning specimen or timed collection.
What should you not do before a urine test?
- Avoid alcohol, coffee, tea, tobacco and strenuous exercise for 24 hours prior to collection and up to collection time. - Do not consume avocados, bananas, eggplant, pineapples, plums, tomatoes or walnuts for 48 hours before the test.
How long do cytology results take?
Routine biopsy and cytology results may be ready as soon as 1or 2 days after the sample gets to the lab. But there are many reasons some take much longer to complete.
What is the purpose of cytology test?
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 are the steps involved in preparing cytology sample?
In the cytology laboratory various sample preparation steps are performed prior to analysis including centrifugation to concentrate cells in dilute samples, followed by preparation and staining of slides, and examination under a light microscope (Figure 1).
Is cytology a biopsy?
A cytology test is different from a biopsy. 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.
Who will send urine cytology results to?
Results. The pathologist will send the results of your urine cytology test to your doctor, who will report the results to you. Ask your doctor how long you can expect to wait for your results. Different labs have different ways of describing the results of a urine cytology test.
Why do we do urine cytology?
Why it's done. Urine cytology is used with other tests and procedures to diagnose cancers of the urinary tract , including: It's generally used for people who have signs or symptoms of urinary tract cancer, such as blood in the urine. Urine cytology can best detect larger and more-aggressive urinary tract cancers.
How to do a cytology test?
In some cases, a urine sample is collected using a thin, hollow tube (catheter) that's inserted into your urethra and moved up to your bladder.
What is the male urinary system?
Male urinary system. Your urinary system — which includes your kidneys, ureters, bladder and urethra — removes waste from your body through urine. Your kidneys, located in the rear portion of your upper abdomen, produce urine by filtering waste and fluid from your blood. Urine cytology is a test to look for abnormal cells in your urine.
What is the best way to check for cancerous bladder?
If atypical or cancerous cells are detected, your doctor will likely recommend a cystoscopy procedure and a CT scan to further examine your bladder and urinary tract. By Mayo Clinic Staff.
Which organs remove waste from the body?
Your urinary system — which includes your kidneys, ureters, bladder and urethra — removes waste from your body through urine. Your kidneys, located in the rear portion of your upper abdomen, produce urine by filtering waste and fluid from your blood.
What does it mean when a urine sample is unsatisfactory?
Unsatisfactory specimen. This can mean that not enough cells or the wrong types of cells were found in your urine sample. You may need to repeat the test.
What to do if you don't collect your urine?
If you feel that you didn’t collect your urine properly, obtain another urine jar and try again.
Can you take urine specimens at any time of day?
NOTE: The first specimen of urine for the day is not suitable for cytology. The specimen can be taken at any other time of the day.
Can you collect the first part of urine?
DO NOT collect the FIRST PART of the urine you pass. This urine always contains contaminating organisms. Collect the MIDSTREAM or middle flow of urine into the jar provided until the jar is at least half full. Label the container with your surname, first name, date of birth and date and time of collection.
How far in advance do you need to make an appointment for a lab?
Appointments must be made at least two hours in advance. Walk-ins are also welcome. Please note: not all lab locations offer all services
Can urothelial carcinoma be diagnosed by cytology?
Low-grade papillary transitional cell or urothelial carcinomas may not be diagnosed by cytologic examination. Calculi or recent instrumentation may produce atypical changes in urothelial cells simulating malignancy. Chemotherapy and radiation may also produce changes stimulating neoplasia. Viral culture is the method of choice for the diagnosis of CMV but cytology can provide faster results.

Risks
- Risks of urine cytology testing depend on how your urine is collected. Most often, people undergoing the test urinate into a sterile container, which carries no risk. Collecting urine by inserting a hollow tube (catheter) into your urethra carries a risk of urinary tract infection.
How You Prepare
- Schedule your test for after your first morning urination. Cells held overnight in your bladder, which are eliminated during your first morning urination, might be degraded, making them difficult to analyze in the laboratory.
