My daughter 15 and i went to the ed for her reoccurring chest pain and high heart rate. they done a urine test and the result said she has ketones, protein and white blood cells in her urine. but no sign of an infection. blood sugar was 5.1?

The blood sugar was normal. If the urine protein was more than a trace or 1+ positive,I recommend having a 24 hour urine collection measured for total protein as well as an immunofixation to look for chronic kidney disease and other disorders. If the total protein spilled exceeds 150-200 mgs,I recommend consulting a nephrologist for evaluation & advice.
