A few questions help us personalize your report.
A positive dipstick blood test on urinalysis indicates haematuria (blood in the urine) or haemoglobinuria, and always requires follow-up to identify the cause. Even microscopic haematuria — blood invisible to the naked eye — warrants investigation for kidney stones, urinary tract infection, glomerulonephritis, or, in adults over 40, bladder cancer. A positive dipstick result should be confirmed with urine microscopy to determine whether actual red blood cells are present (versus free haemoglobin from haemolysis).
Positive occult blood can originate from glomerulonephritis, kidney stones, bladder cancer, or UTI. Myoglobinuria also triggers a positive dipstick. Negative is expected.
Optimal is negative. Persistent hematuria in patients over 35 needs full urologic evaluation.
