The routine urinalysis contains more than twenty indicators, and the urinalysis of simple nephritis usually does not check only three. The actual nephrologist is a person who is a member of the nephrologist’s team, and the nephrologist is a person who is a member of the nephrologist’s team, and the nephrologist is a person who is a member of the nephrologist’s team, and the nephrologist is a person who is a member of the nephrologist’s team, and the nephrologist is a person who is a member of the nephrologist’s team, and the nephrologist is a person who is a member of the nephrologist’s team. The nephritis will lead to damage to the glomerular filtration barrier, which in turn will lead to increased permeability of the glomerular basement membrane, increased plasma protein leakage, excess protein over renal tubular reabsorption will lead to an increase in urinary protein levels; 2. urinary red blood cells: microscopic does not contain or contains only 2-3 red blood cells, the number of cells per high-powered microscope > 3 when the urinary red blood cells positive. The kidney parenchyma is damaged and bleeding, and the discharge of red blood cells with the urine will lead to positive urine red blood cells or occult blood indicators; 3, urine specific gravity: urine specific gravity is mainly an indicator of the dilution and concentration function of the kidneys, but the changes in urine specific gravity are not consistent in different types of nephritis patients. The most important thing is that the patient’s urine is not only a good source of energy, but also a good source of energy. The urinalysis indexes should be referred to according to the different nephritis.
