My daughter 7yrs tested for second time proteinurea. she has low diuresis both times 500-600ml. normal albuminuria. high proteinuria per l and normal per day. please why is it high per litar and normal per day? what does it mean? kidneys?

Negative albuminuria rules out primary kidney problem but systemic diseases which cause other type of proteins in the urine, e.g. light chain, can be present. Severe cystitis can also produce significant protein (immunoglobulin types) in the urine and they are measured in total proteinuria by quantitative test. Again, (-) albuminuria rules out glomerulopathy.

Proteinuria in a child should be investigated by a Nephrologist for there can be many conditions which can cause this. Good luck
