What does it mean when urine occult blood is negative?

A negative urine occult blood test indicates that no abnormal red blood cells are detected in the urine analysis, meaning there is no blood component in the urine. This is typically a normal test result. 1. Normal condition: In healthy individuals, urine normally contains no red blood cells or only trace amounts (0–2 per high-power field), so a negative occult blood result may simply reflect normal physiology. 2. Disease resolution or mild condition: In certain urinary system disorders—such as urinary tract infections, kidney stones, or pyelonephritis—the occult blood test may yield a negative result when inflammation is mild or after the condition has resolved. 3. Specimen issues: Improper urine sample collection, inadequate storage of the specimen, or excessive intake of vitamin C may lead to false-negative results.
