Urine protein test (PRO)

There are often quantitative proteins in the blood that are essential for human life. A portion of the protein is filtered into the urine in the kidney's spheroids, but is absorbed back into the bloodstream. Therefore, if the function of the kidney is normal, the amount of protein present in the urine is only a little bit, but when the kidney and the urinary tract are obstructed, a large amount of protein is leaked into proteinuria. A test for investigating this protein in the urine is called a urine protein test. There are two types of examination methods for urine protein: qualitative examination and quantitative examination. Qualitative examination is to put a test or test paper in the urine, check the presence of proteinuria according to the degree of discoloration, and the quantitative test is to investigate the amount of protein contained in the urine. From these tests, you can see if there is any obstacle to kidney function. Urine protein qualitative test often uses semi-quantitative or plus mode to detect the amount of protein excreted in urine. The result can be expressed as negative, trace, 1-4 plus signs, and can also be expressed by numerical values. The more plus or the higher the value The higher the urine protein, the more. If the urine protein qualitative test is positive, the urine protein quantitative test should be further carried out. Basic Information Specialist classification: urinary examination classification: urine / kidney function test Applicable gender: whether men and women apply fasting: fasting Analysis results: Below normal: Normal value: no Above normal: negative: normal. Positive: 1. It can be seen in acute nephritis, chronic nephritis, pyelonephritis, renal tuberculosis, renal tumor, nephrotic syndrome caused by various causes, systemic lupus erythematosus, diabetic nephropathy, urinary tract inflammation, and rejection after renal transplantation. The appearance of proteinuria may also be caused by certain pathological reactions, such as high fever, high blood pressure, cystitis, urethritis, tumor, myeloma, transfusion reaction. 2. Pregnancy, strenuous exercise, cold, mental stress, position changes, rapid growth of adolescents, etc.; if the urine is mixed with vaginal secretions or mixed with sperm, or contaminated by some other substances can also cause false positives, should Pay attention to review and observation. Tips: It is forbidden to exercise vigorously and heavy physical labor. It is forbidden to take foods with high protein content. Normal value Normal people have trace amounts of protein in the urine, and the normal range is qualitatively negative, which is recorded as (-). Clinical significance Urine protein detection can be used for early detection of diseases of the kidney and other systemic systems. It is suitable for healthy human examination, increased urinary foam, or symptoms such as edema, low back pain, high blood pressure, etc., and is also used to evaluate chronic glomerulonephritis. The efficacy of nephrotic syndrome. When the protein content in the urine is as high as 0.15g/24h or more, it is called proteinuria, and urine can be qualitatively positive. The amount of protein contained in different markers is approximately (-) means urine protein 0.1g / L; (±) indicates that the urine protein is between 0.1 g and 0.2 g/L; (+) indicates that the urine protein is between 0.2 g and 1.0 g/L; (++) indicates that the urine protein is between 1.0 g and 2.0 g/L; (+++) means that the urine protein is between 2.0g and 4.0g/L; (++++) means that the urine protein is >4.0 g/L; Urine protein positive is more common in Pathological factor If the urine protein is qualitatively positive, it should be noted and should be further examined or reviewed. Sustained positive results, especially when the plus number is high, suggest that you may have acute nephritis, chronic nephritis, pyelonephritis, renal tuberculosis, kidney tumor, nephrotic syndrome caused by various causes, systemic lupus erythematosus, diabetic nephropathy, urinary tract inflammation, Rejection after kidney transplantation, etc. The appearance of proteinuria may also be caused by certain pathological reactions, such as high fever, high blood pressure, cystitis, urethritis, tumor, myeloma, transfusion reaction. 2. Physiological factors Can cause temporary urine protein positive, such as pregnancy, strenuous exercise, cold, mental stress, body position changes, adolescent rapid growth period, etc.; if the urine is mixed with vaginal secretions or mixed with sperm, or contaminated by some other substances Can also cause false positives, should pay attention to review and observation. 3. Other factors Occasionally, when the urine protein test result is positive, attention should be paid to observation and review, and the relevant physiological factors should be excluded, and the physician or other further examination should be consulted to determine the cause. Positive results may be diseases: urinary sensation in children, occult nephritis, occult glomerulonephritis, renal insufficiency Before the test: It is forbidden to exercise vigorously and heavy physical labor, and it is forbidden to take foods with high protein content. When checking: Relax your body and eliminate tension and anxiety. Inspection process The urine of the subject was collected and detected by a test paper method, a sulfonic acid method, and a heated acetic acid method. Not suitable for the crowd Generally not. Adverse reactions and risks No.
