What exactly does it mean when you have few bacteria in your urine?

Often not a concern.: When urine is studied in a lab (urinalysis and/or culture), the lab staff will study the urine under a microscope. They may see (or culture) bacteria. These may represent a true bacterial infection, or in some instances if they are very few in number and if there is no accompanying inflammation, the bacteria may be a contaminant from the skin from the time of specimen collection. Ask your doc.
