The interpretation of urinalysis takes into account the results of physical, chemical and microscopic examination and the person's overall condition. Urine test results should always be interpreted using the reference range provided by the laboratory that performed the test, or using information provided by the test strip/device manufacturer.

But a new urine test could be developed to detect the beta-catenin mutated form of liver cancer after researchers at the Cancer Research UK Beatson Institute in Glasgow found a metabolite in mice.
The test commonly checks for infection, inflammatory disease of the urinary tract, cancer, or precancerous conditions. It can be part of a broader urinalysis . If a cancerous condition is detected, other tests and procedures are usually recommended to diagnose cancers, including bladder cancer , ureteral cancer and cancer of the urethra .
A urine test is any medical test performed on a urine specimen. The analysis of urine is a valuable diagnostic tool because its composition reflects the functioning of many body systems, particularly the kidneys and urinary system , and specimens are easy to obtain. [ 1 ]
The objective of cancer screening is to detect cancer before symptoms appear, involving various methods such as blood tests, urine tests, DNA tests, and medical imaging. [ 1 ] [ 2 ] The purpose of screening is early cancer detection, to make the cancer easier to treat and extending life expectancy. [ 3 ]
The Food and Drug Administration (FDA) has recently approved a blood test screening for colorectal cancer that has an over 83% success rate at detecting the presence of this form of cancer.
The test had a 95% sensitivity among men who had a grade group 2 or greater cancer; this sensitivity improved to 99% in men with a grade group 3 or greater cancer. In practical terms, that means ...
The detection limit of a test is the concentration at which the test starts to turn from negative to positive. Although the detection limit may vary between urine samples, the detection limit is defined as the concentration of the analyte that results in a positive reaction in 90% of the examined urines.
