At a glance

There are a number of diseases in which high-quality urine diagnosis can have a preventive, supportive or sometimes decisive function. Basically, a urine test is necessary whenever, for example, the doctor wants to determine the exact composition of the urine. Urine values that deviate from the norm may give initial indications of a underlying disease.

Many of these diseases, especially those of the kidneys, are symptom-poor and diagnosis is often only at a highly advanced stage of the disease.

However, there are some symptoms where the examination may be useful:

  • Increased drinking need (polydipsia)
  • Blood in the urine
  • Lack of ability to sweat (anhidrosis)
  • Weight loss
  • Abdominal pain
  • Cravings
  • Sugar smell of urine
  • Breakthrough pain
  • Urinary retention

In principle, medical professionals should always be consulted in the event of substantial suspicions or persistent complaints.
