Reasons for a plus sign in male urine protein

Normal urine is light yellow with a slight odor. However, the urine of many male friends is not like this. For example, there is foam and the urine protein content is high or the urine has a pungent smell. There are many reasons for abnormal urine, such as daily life, eating habits, etc. High urine protein is a problem that cannot be ignored. Its detection is generally indicated by a plus sign. So what is the reason for a plus sign in urine protein?

Urine protein is a protein detected when urine becomes cloudy after acidification and heating. The range of urine protein in a normal person for 24 hours is 0.15g, and routine laboratory tests are negative. When urine protein is detected at 150 mg/day, that is, urine protein is positive, it means that the amount of urine protein excreted by the human body has increased significantly, which is abnormal urine protein. Continuous positive urine protein often means that the kidneys have lesions, so the degree of kidney disease damage and the effect of kidney disease treatment can be determined clinically based on the amount of urine protein positivity. Therefore, when abnormal urine protein appears, it must be effectively controlled and eliminated to prevent the disease from worsening.

Normal urine contains no or only trace amounts of protein, and the test result is negative (-). When the protein content in urine rises to a certain amount, the test result is positive (+). Urine protein 1+ (a plus sign) is the result of a 24-hour urine protein quantitative test. It can also be expressed as urine protein plus sign, urine protein +1, and the several expressions all mean the same thing. Urine protein plus sign means that 1L of urine contains 0.2-1.0g of protein, that is, 0.2-1.0g/L.

Cause: Under normal circumstances, there is only a very small amount of protein in the urine. The presence of urine protein+ in urine tests is related to diet, exercise, and kidney disease. If urine protein+ only appears once, it may be transient. It is necessary to recheck urine routine several times, and if necessary, perform a 24-hour urine protein quantitative test to determine whether the kidney function is damaged. Generally, when the glomerular filtration barrier is damaged, protein will leak out. Experts point out that due to diseases such as interstitial nephritis, analgesic nephropathy, renal tubular damage caused by chronic cadmium poisoning, and various congenital metabolic defects, renal tubular function defects are caused. Although the amount of protein filtered out by the glomerulus has not increased, the ability of the renal tubules to reabsorb protein has decreased, and protein has appeared in the urine.

After knowing what urine protein is and what causes it, I believe male friends have already made up their minds, that is, to observe their own urine. Once the urine is abnormal, they must go to the hospital for examination in time. Even if the urine protein test result is only a plus sign, it should not be underestimated and treatment should be sought as soon as possible.
