How do you test for bladder cancer?
In a urine cytology test, a sample of the patient’s urine is analyzed under a microscope. 1,2 This test can reveal the presence of cancer cells or cells that are pre-cancerous, meaning that they are more likely to become cancer cells later. However, this test is not enough to provide a definite diagnosis on its own—it is possible for cancer cells to be present in the bladder even if no …
What is the best test for bladder cancer?
· Recent analyses indicate that urine cytology detects only around 50% of high-grade tumors and 10% of low-grade tumors, with an overall sensitivity for bladder cancer detection of approximately 40%. 1 This means that overall, approximately 60% of all bladder cancers will be missed by urine cytology. While a positive urine cytology result does reliably indicate the …
What are signs of bladder cancer?
· Urine tests: A urine test can help detect bladder cancer in a small number of cases. A urine routine and microscopic test may reveal the presence of blood in the urine. Further, a urine cytology test can be ordered. This test involves testing samples of urine for three consecutive days and is called three-day urine cytology test.
Can bladder cancer be found early?
Some doctors find these urine tests useful in looking for bladder cancers, but they may not help in all cases. Most doctors feel that cystoscopy is still the best way to find bladder cancer. Some of these tests are more helpful for finding bladder cancer that has come back in someone who has already had it, rather than first diagnosing it. Cystoscopy

What is the best test for bladder cancer?
Several types of urine test have an important role in the overall process of diagnosing bladder cancer. Among these tests, urine cytology and urine tumor marker tests are used to detect the presence or absence of bladder cancer. Urine cytology has been used to assist bladder cancer diagnosis for over 75 years and has well-established strengths and limitations which are discussed in more detail below. Molecular tumor marker tests such as Cxbladder have been more recently developed, and provide high diagnostic accuracy in both detection and rule-out.
How to collect urine samples?
Urine samples are usually obtained by spontaneous voiding, using the clean-catch, midstream urine collection method. This involves voiding the first portion of urine into the toilet, collecting the midstream portion into a clean container, then voiding the remaining portion into the toilet. This method greatly reduces the risk of contaminants entering the sample. Less commonly, an invasive method of urine collection, such as placement of a urinary catheter, may be required.

Abnormal findings in a urine test can be characteristic of certain disease processes. For instance, persistently elevated protein in urine is a common early sign of chronic kidney disease, high levels of glucose may indicate diabetes, the detection of bacteria is often associated with a UTI, and the presence of red blood cells or abnormal cells may indicate bladder cancer.
What is urine made of?
Urine is made up of several components including water and waste materials filtered from the blood by the kidneys, as well as small numbers of cells such as epithelial cells shed from the lining of the urinary tract and possibly red and white blood cells . The type and quantity of the different components and cells contained in urine can provide important information regarding an individual’s health, which can help in the diagnosis of diseases such as bladder cancer.
What is the test used to detect RNA in urine?
In recent years there has been increasing use of molecular diagnostic tests to detect specific proteins or nucleic acids (RNA or DNA) in urine to diagnose diseases such as UTIs, prostatitis, or bladder cancer. Cxbladder, for example, measures the urine concentration of messenger RNA (mRNA) expressed by five biomarker genes to determine the presence or absence of bladder cancer.
What are the physical properties of urine?
Urine samples are routinely examined for physical properties (e.g., color, clarity, odor, density), chemical composition (e.g., pH, protein, glucose; commonly determined by a simple dipstick test) and microscopic appearance (e.g., the presence of cells, crystals, or bacteria).

Cystoscopy. If bladder cancer is suspected, most doctors will recommend a cystoscopy. . A urologist uses a cystoscope, which is a long, thin, flexible tube with a light and a lens or a small video camera on the end. For details on how this procedure is done, see Cystoscopy.
What is the blue light in a cystoscopy?
Fluorescence cystoscopy (also known as blue light cystoscopy) may be done along with routine cystoscopy. For this exam, a light-activated drug is put into the bladder during cystoscopy. It’s taken up by cancer cells. When the doctor then shines a blue light through the cystoscope, any cells containing the drug will glow (fluoresce). This can help the doctor see abnormal areas that might have been missed by the white light normally used.

What is ultrasound imaging?
An ultrasound (which may also be referred to as a sonogram) uses high frequency sound waves to produce images of internal organs. Echoes, which are created as sound waves bounce off organs and tissues, produce computer images that provide information on the structure and movement of organs and the blood flow through vessels. An ultrasound does not use radiation or contrast dyes.
Can ultrasound help with bladder cancer?
An ultrasound of the urinary tract can help assess the size of a bladder tumor and whether a bladder cancer has spread. Ultrasound is able to differentiate between fluid-filled cysts and solid tumors, however, it cannot determine if a tumor is cancerous. Ultrasound can also be used to guide a biopsy needle to sample a suspected cancer.
Can imaging be used to diagnose urinary tract tumors?
Irregularities in the upper urinary tract are often assessed with imaging given its accuracy in this setting and an inability to access the region via cystoscopy. In contrast, imaging techniques are less useful for diagnosing tumors in the lower urinary tract. Small and flattened bladder tumors may also be difficult to visualize with imaging.
