Macroscopic haematuria is Urology

Microscopic haematuria is Nephrology, or in people over say 40-50 may be urological. It is common in healthy people and investigation should be limited and proportionate. Microscopic haematuria can be detected by testing urine with a urine dipstick test. These are commercially available biochemical tests on a strip. This is an example of a near-patient test.

Actual confirmation of dipstick detected microscopic haematuria by light microscopy may not be helpful as erythrocytes may lyse in acidic urine and after prolonged storage.[2] The Papanicolaou staining process also includes a fixation step with glacial acetic acid, that also causes haemolysis.
