What can urine test reveal

Urine test is a common test among many tests. In fact, a lot of things can be checked in urine, because the substances contained in urine can determine whether the body is healthy and if there are any abnormal conditions. Urine tests can detect a variety of diseases such as cystitis, nephritis, diabetes, etc. In addition to detecting diseases, urine tests can also check whether the body is pregnant.

Urinalysis is one of the “three major routine” items in medical examinations. Proteinuria or formed elements in urine sediment can be seen in the early stages of many kidney diseases. It also has important reference value for the diagnosis of certain systemic diseases and diseases of other organs in the body that affect urine changes, such as diabetes, blood diseases, liver and gallbladder diseases, hemorrhagic fever, etc. At the same time, urine tests can also reflect the treatment effect and prognosis of some diseases.
