Urine test is usually the most common type of examination item, there are a lot of tests, the most common of which is urine protein, many people will find that their urine protein there will show 1+.
Because proteinuria indicates that the kidneys are not good, I am very worried about seeing abnormalities in this indicator.
Is urine protein 1+ a bad kidney?
Under normal circumstances, there is no urine protein in the urine, because the normal protein molecules are relatively large and cannot be excreted into the urine through the kidney glomeruli, so in most cases, the positive urine protein found in the urine will have a certain relationship with kidney disease.
However, if only occasional tests find urine protein 1+, there is no need to worry about it, which does not mean that there is kidney disease. There may also be physiological reasons, such as eating too many high-protein foods, too nervous and agitated, strenuous exercise, etc. may lead to high urine protein.
How to know that the kidneys are not good
Or physiological reasons
In general, when the first test finds urine protein 1+, if other tests are normal, the possibility of nephropathy is generally not considered, and if it is accompanied by other nephropathy indicators, it means that it is nephropathy.
Or you can pass the 24-hour urine protein quantitative examination, because this test is the gold standard to judge the degree of urine protein, if the test results are abnormal, it is mostly caused by pathological causes, it is likely to be caused by kidney disease, must not be careless, because there are many types of kidney disease, to find out what type, some kidney disease even if there is only one +, may be more serious.
Of course, in most cases, the more plus signs, the more serious the disease, only one +, the disease is relatively mild.
What indicators of kidney weakness refer to urine?
Urine protein
Urine protein is an important indicator to judge kidney disease, if there is a + sign or 24-hour quantitative urine protein test beyond the normal range of 3 consecutive examinations in the morning during the week, it means that it is pathological proteinuria, mostly related to kidney disease.
Urinary erythrin
Urinary hemoglobin can be seen in the urine If each high-power field of red blood cells has more than 5, indicating that there is hematuria, it is also abnormal, mostly related to kidney disease or urinary tract infection, must not be careless.
Urinary leukocytes
White blood cells are an indicator of inflammatory infection, and the more white blood cells there are, the more pronounced inflammation is. Generally speaking, if it is greater than 5/high magnification field, it means that there is inflammation, which may be nephritis. Of course, it can also be cystitis or urethritis, etc.
