My 12 year old son has been experiencing lower left sided back pain for 3 weeks. I took him to the pediatrician who ran blood and urine tests. The abnormal labs are as follows: 24 hour urine: 465 mg protein,
Bun: 20mg, Creatinine: 0.7mg, Bun to Creatinine Ratio: 29. ANA positive at 1:80. I know these are not normal, but no one seems to be able to tell me what could be going on. We have an appointment with a nephrologist in 3 weeks, but any information anyone has would be greatly appreciated.
