I am not able to provide a specific diagnosis based on the information that you present. I do not recognize any kidney disease based on the information that you present. There are no normal values for a random urine creatinine as this value is used to judge other constituents of the urine such as protein, sodium, potassium and other chemicals in the urine. A single stranded anti-DNA antibody (SSdna) is of no consequence.
I suggest that you continue to consult with your physician about your symptoms and your concerns.
