Seeing a kidny dr in1 mo. Worried-trace blood&30mg/dl urine sample&rbc was 2/scale 1-2. 24hr urine protein was 150? What' are possiible causes in 30yr f

May be normal. The findings you described may be normal for a woman. In a man it would be worth rechecking for rbc.
Looks normal . Protein of 150 mg per day is considered within the normal limit defined as a maximum of 300 mg per day. A more specific test would be for microalbuminuria which is common in diabetics. The RBC count is also normal so i would not worry too much.
