On urine test results, urine hemoglobin=trace-intact, urine microscopic = indicated, wbc/hpf=0-3, rbc/hpf=0-3. What do these results & terms mean?

Normal. The WBC and rbc are referring to the number of white blood cells and red blood cells seen in a range of microscopic fields of sampled by the lab technician. The number of these cells (0 to 3) for both types of cell is within the normal limits expected. These normal, scattered red cells are enough to cause a trace of hemoglobin on the chemistry test. So these are all normal results.
