Haematuria refers to the presence of red blood cells in urine, which can originate from any part of the urinary system—the kidneys, ureters, bladder, or urethra. This condition is classified into two main categories: gross haematuria (visible blood that changes the urine colour) and microscopic haematuria (blood cells detectable only through laboratory testing). While often benign, haematuria warrants proper medical evaluation to rule out underlying conditions.
Gross hematuria presents as visibly discoloured urine that may appear pink, red, or dark brown like cola or tea. Small amounts of blood in urine can cause noticeable colour changes. This type often prompts immediate medical consultation due to its alarming appearance. The intensity of colour doesn’t necessarily correlate with the severity of the underlying condition.
