A concerned male athlete brings a clear red urine specimen to the physician's office The patient reported that the urine appeared cloudy when he collected it the previous evening, but it was clear in the morning. Is this possible? Explain your answer.

Yes.

The kidney is the part of the internal organ that help in the production of urine. And a normal urine should be yellowish in color.

Therefore, in a situation whereby the urine is seen to contain some red tiny droplets, specifically means the presence of an infection to the kidney.

In this case, a cloudy urine might mean the presence of white blood cell which stipulates the presence of infection.
