What does it mean if the 24-hour urinary protein quantification is high?
Disease description:
My eyes are both swollen in the morning, and my urine protein test shows a slightly high level. Why is the 24-hour urine protein quantification elevated?
Doctor's answer (1)
Dr. Liu Feng
Conditions associated with elevated 24-hour urinary protein quantification include the following:
1. Physiological causes: Transient proteinuria may occur under conditions such as vigorous exercise, emotional stress, high fever, or pregnancy. This typically does not require specific treatment and can be relieved with rest.
2. Glomerular diseases: The glomerulus is the structure in the kidney responsible for filtering blood. When it is damaged, as in conditions like nephritis, diabetic nephropathy, or hypertensive kidney injury, large amounts of protein may leak into the urine, presenting symptoms such as high fever and back pain.
3. Tubular diseases: Renal tubules are responsible for reabsorbing useful substances, including some proteins, from the filtered fluid. Tubular damage can lead to increased urinary protein levels and is commonly seen in cases of drug toxicity or heavy metal poisoning.
4. Overflow proteinuria: When there is an excessive amount of abnormal proteins in the blood exceeding the reabsorption capacity of the renal tubules, such as an increase in light chain proteins caused by multiple myeloma, proteinuria may also develop.
If you have any concerns, timely medical consultation is recommended.
