Once the urine sample has been collected, a technician will keep it in favorable conditions for the reproduction of microorganisms. Under normal circumstances and in the absence of infection, only a small amount of germs are found in a person's urine. If a greater amount of germs is detected, the technician will use a microscope or chemical tests to determine the specific type of germs that are growing in the culture. In the event that the doctor diagnoses an infection, the technician will also perform tests to determine which medications will be the most effective in eliminating the detected microorganisms.
It is known as the sedimentation.. this process spreads widely (horizontally) keeping the youngest on the top and the oldest at the bottom.. hope this helps:)
