First, there is no abnormality of red blood cells and hemoglobin in blood routine, but there may be microangiopathic hemolytic anemia with negative Coombs test in patients with rapidly progressive hypertension. Patients with abnormal red blood cells and high hemoglobin have increased blood viscosity, and are prone to thrombosis complications (including cerebral infarction) and left ventricular hypertrophy.

Second: in the early stage of urine routine, the urine routine of patients is normal. When the renal concentration function is damaged, the urine specific gravity gradually decreases. There may be a small amount of urine protein and red blood cells. Occasionally, the tube type can be seen. With the progression of renal disease, the amount of urine protein increased. In patients with benign nephrosclerosis, if the 24-hour urine protein was more than 1 g, the prognosis was poor. The number of red blood cells and tube type can also increase, and the tube type is mainly transparent and granular.

Third: renal function is estimated by blood urea nitrogen and creatinine. In the early stage, there was no abnormality, and the renal parenchyma began to rise when it was damaged to a certain extent. Adult creatinine > 114.3% μ 5 mol / L in the elderly and pregnant μ It is suggested that there is renal damage when the concentration is 10 mol / L. Phenol red excretion test, urea clearance rate and endogenous creatinine clearance rate were lower than normal.
