What reason is albuminuria positive caused

summary

Urine protein is a standard for testing renal disease. Positive urine protein will reflect renal disease. So what is the cause of positive urine protein? Let me explain it for you.

What reason is albuminuria positive caused

First, due to various causes of glomerular capillary wall damage (such as immune damage), the load is reduced or lost, resulting in increased glomerular permeability. After filtration, more plasma proteins exceed the reabsorption capacity of renal tubules, resulting in urinary protein. Such as acute and chronic nephritis, lupus nephropathy, diabetic nephropathy, etc.

Second, when the renal tubule has pathological changes or renal tubular function defect, the protein reabsorption decreases or the secreted protein increases, which leads to the increase of urine protein. Such as renal tubular acidosis, nephrosis caused by analgesics, nephrotoxicity of antibiotics and so on.

Third, overflow urine protein weakly positive (also known as coagulative proteinuria): the patient's urine is turbid when heated to 40 ℃, coagulated when heated to 60 ℃, and dissolved when heated to 100 ℃. It is often found in myeloma, primary amyloidosis and macroglobulinemia.

matters needing attention

Urine protein positive can cause kidney disease, so in peacetime to strictly control their diet, pay attention to healthy diet, drink more water, eat less stimulating food, go to the hospital regularly.
