What issues you should cover

Haematuria is defined as ≥3 red blood cells in the urine per high power field. Macroscopic haematuria means that the urine is visibly red. However, red, pink, tea coloured, brown, or black urine may, on microscopic examination, contain no red blood cells. Although usually benign and associated with urinary tract infection or kidney stones, and often self limiting and not having any identifiable cause, haematuria may also be a sign of malignancy or kidney disease.
