Should we be concerned about our daughters blood work for possibly kidney issues?
She is 3 years, 4 mos old
Weighs 29 pds
Height, 35.5 inches
RBC 3.91 Low
BUN/Creatinine Ratio 37
Immunoglobulin A 36
Immunoglobulin M 160
Her BUN/Creatinine Ratio 6 weeks ago was 35
It was also just discovered that she has several renal cysts in both kidneys, the largest of which measure 1cm x 1cm in one kidney (her kidney measures 9cm x 9cm) and the largest in the second kidney .9x.1cm while the other cysts are smaller.
I am not sure what her kidney diagnosis is or why these studies were done in the first place. Is there a history in the family of polycystic kidney disease? Did she have an infection and the ultrasound was prompted by the infection? I need a bit more history before I can answer this question.
I have not found the ratio of BUN to creatinine to be very helpful in the pediatric world. Most of us would follow the serum creatinine value as a marker of renal compromise. The ratios you have described are essentially not changed.
Good luck, Dr. Olson
