There are no symptoms for kidney disease until it becomes quite advanced, therefore it's possible to live with the condition without realising.
But research has shown that some people are at higher risk of developing kidney disease than others and should therefore have their kidney function checked even if they feel well.
Early diagnoses of kidney disease ensures patients are given treatment to relieve symptoms when they do appear.
Treatment can also help slow or prevent progression of the condition, and reduce the risk of developing related problems.
Use the below test, created by the NHS, to see if you're at high risk of developing kidney disease and should have your kidney function checked.
