My 4 year old has had microhematuria for 8 months. No protein, normal kidney function. Seeing nephrologist, who ordered 24 hour urine and labs. C3 and C4 are low, urine showed abnormal (glyoxolate?? or glycolate?) (pre-cursor to stones). Nephrologist is confused as to whether it's stones or kidney lesion. Waiting on further immune tests before proceeding with biopsy.
In your opinion, is a biopsy absolutely necessary? What are the possible diagnoses? With the low complement, is it safe to assume this is NOT stones? How could it be stones if her urine is only showing pre-cursor to stones? We don't go back for several weeks, as he is buying us time to decide on the biopsy while we wait for the immune tests as well.
Also, can she be vaccinated with low complement? Are there any risks to her taking probiotics? Thanks!
