My daugther 8yrs was tested for proteinurea. we revieved 2 results. proteinurea per litre and proteinurea per 24h. the result per litre is high and per 24h is in normal range. why and what is the diffterence between these 2 results?

If the 24 hour urine collection is accurate then the 24-hr result is more accurate. However, it is almost impossible to have an accurate urine collection in children so the total volume will be less which results in a lower total protein. Because of the difference, random urine for protein/creatinine or albumin/creatinine should be able to confirm or rule out abnormal proteinuria or albuminuria.

Most physicians evaluate proteinuria by a 24 hr collection and find it accurate
