Hi, why should exercising cause a trace amount of blood in urine test? also if orange juice, coffee, and cola is drank within 3 or 4 hrs of urine test at Physician's office can that give false creatinine and albumin readings?

In brief: Myoglobin

Working out hard releases a little myoglobin into your bloodstream and thence the urine, and pounding the pavement can wreck some red cells and their contents leaks into the urine.
There is no "false" creatinine urine assay; it's a normal component that varies with your muscle mass. It won't give false albuminuria. The most common cause of protein in the urine is orthostatic proteinuria, harmless

Agree with Dr. Friedlander. Would recommend checking blood pressure, blood glucose and do follow-up testing as advised by your doctor.
