As a result of microorganisms breaking down the urea in the urine, the urine begins to smell like ammonia. Its pH is raised, turning it alkaline. Any existing bacteria or cells will keep consuming the glucose (sugar) in the urine. Testing for glucose levels in your urine will likely produce erroneous results. Along with changing color, the urine also gets hazy or cloudy. A urine examination is recommended within 30 minutes of collection.
