Is a urine RBC level of: 50 x10^6L normal. And a urine WBC level of 60 x10^6L.

No. The urinalysis microscopic test shows an elevation of red blood cells and white blood cells which may represent an infection and or ureteral/and or kidney stone and or kidney pathology, you should go over the test results with your doctor or primary care provider,
I hope this helps.
