A rapid urine test is the quickest way to test urine. This involves dipping a test strip with small square colored fields on it into the urine sample for a few seconds. After that you have to wait a little for the result to appear. However, they are not intended for self-diagnosis purposes, and should be used in consultation with a doctor.
