Gross haematuria is obvious to the patient and is usually followed up, appropriately, by a complete urological work up. The much commoner microscopic haematuria, however, may not always receive the attention that it deserves. Dealing with this symptom adequately in the general practitioner's surgery requires a substantial body of knowledge. Recent developments warrant a re-examination of this topic.

Microscopic haematuria is rare before the age of 50 (occurring in fewer than one in 100 people of this age); after 50 the prevalence rises sharply and varies from 2% to 18% ^{1 2} (with some of this variation explained by different definitions). The commonly used dipstick test gives a yes or no answer to the question of whether microscopic haematuria is present and semiquantitative information at the same time.
