Urine Bacteria (Microscopy)
A microscopic look at your urine sediment counts bacteria that may be present. Small numbers can come from normal skin or genital flora picked up as the sample passes out of the body.
Bacteria seen together with white blood cells and symptoms like burning or urgency can point toward a urinary tract infection. On their own, especially in a sample that wasn't collected cleanly, bacteria are often just contamination and don't necessarily mean infection.
Many bacteria in the sediment, particularly alongside white blood cells, nitrites, or leukocyte esterase, suggest a possible urinary tract infection. A urine culture is the usual next step to confirm whether an organism is truly growing and which antibiotic would treat it.
Few or no bacteria is the expected, reassuring result and makes a urinary tract infection unlikely at the time of the sample.
Few or no bacteria is normal. Because contamination is common, your clinician interprets bacteria alongside symptoms, other urine findings, and often a culture rather than in isolation.
