Three plus signs of urinary protein

summary

On April 5, I went to the hospital for urination test and found a urine protein. After treatment has improved, then the urine protein 3 plus sign symptoms? Now let's take a look at it!

Three plus signs of urinary protein

Symptom 1: the urine of normal people contains very trace protein, and the routine examination is negative. However, if the glomerular function changes caused by renal disease, resulting in the increase of glomerular filtration membrane permeability, the protein in glomerular filtrate will increase, which will exceed the renal tubular reabsorption capacity and lead to urinary protein dominated by albumin.

Symptom 2: massive proteinuria is the main sign of nephrotic syndrome. The main component is albumin, which also contains other plasma protein components. The change of glomerular basement membrane permeability is the basic cause of proteinuria. The change of charge barrier and mechanical barrier (glomerular capillary pore barrier), the ability of reabsorption and catabolism of renal tubular epithelial cells also affect the formation of proteinuria.

Symptom 3: normal people excrete about 40-80 protein from urine every day, the upper limit is not more than 150 mg, of which the main protein is albumin, followed by glycoprotein and glycopeptide. About 0.60% (60%) of these proteins came from plasma, and the rest came from secretion and tissue decomposition products of kidney, urinary tract and prostate, including urinary enzymes, hormones, antibodies and their degradation products.

matters needing attention

Warm reminder: two plus signs can't show that you have kidney disease, and you need to do further examination. For example, urine routine examination, renal B ultrasound examination, 24-hour urine protein quantitative examination and so on. After a series of examinations, we can get the most accurate diagnosis, and then symptomatic treatment is the most critical, to find the most fundamental cause of urinary protein.
