Hi. I am a 38 yr. old male in more or less good health (as far as I know). I provided a urine sample today. Please note the following results below (the normal ranges are in parenthesis). I am concerned about the RBC count, the trace ketones, and trace protein. What is the cause of this? Should I be concerned?

-RBC, Ur 6-20 /hpf (normal 0-2)

-WBC, Ur NEGATIVE /hpf (normal 0-5)

-Appearance, Ur CLEAR [normal Clear]

-Glucose, Ur NEG mg/dL [normal Negative]

-Ketones, Ur TRACE mg/dL [normal Negative]

-Spec Gravity, Ur 1.028 (normal 1.005-1.030)

-Blood, Ur SMALL [normal Negative]

-PH, Ur 6.5 (normal 5.0-8.0)

-Protein, Ur TRACE mg/dL [normal Negative]

-Nitrites, Ur NEG [normal Negative]

-Leuk Esterase, Ur NEG [normal Negative]

Thank you.
