Five Important Urine Routine Indicators for Kidney PatientsDo you know how to see the urine routine test report? Besides urine protein and occult blood, you should pay attention these five indicators, which can help you have a clear diagnosis of your disease.


Microscopic hematuria is defined as having more than 3 erythrocytes at high magnification. Increased RBCJS occurs more in the urinary system inflammation (including chronic nephritis), tumors, stones and other diseases.

Note that occult blood is not necessarily hematuria. Occult blood is automatically identified by the machine as the components of red blood cells.

"Red blood cell" is different from "red blood cell component". In normal people, red blood cells themselves are constantly destroyed and their components are constantly discharged from the urine. Therefore, sometimes in normal people, the result of urine occult blood "+" appears. The presence of occult blood only indicates the presence of erythrocytes in the urine, not the presence of morphologically complete erythrocytes.

Urinary cast

Urinary cast indicates renal parenchymal damage. It is common in acute or chronic glomerulonephritis and renal failure.

Red blood cell cast helps to demonstrate renal hemorrhage. White blood cell cast helps to identify the site of infection. The presence of granular cast and waxy cast further indicates the worsening or advanced stage of kidney disease. Fatty cast often occurs at Nephrotic Syndrome and chronic nephritis.

Urine specific gravity

Urine specific gravity is the ratio of the weight of urine to the volume of water at 4 degrees Celsius. It is an indicator of solute concentration in urine. And it is used to measure and estimate the concentration function of the kidney, but the accuracy is poor and affected by many factors.

The urine specific gravity of healthy people's 24-hour urine is between 1.015 and 1.025, and it is related to the amount of water intake. Its increase can be seen in dehydration, diabetes and acute nephritis. Its reduction can be seen in diabetes insipidus, chronic nephritis, etc.


Positive: it can be seen in liver substantive lesions and hemolytic jaundice, tissue bleeding, pulmonary infarction, severe burns, fever or constipation.

Epithelial Cells

A large number of squamous epithelial cells can be seen in urinary tract infection.

Transitional epithelial cells can be seen in upper urethral lesions.

Tubular epithelial cells can be seen in acute glomerulonephritis, tubular necrosis, and kidney transplantation.

As one of the three major routine tests, urine routine has a large amount of information, and each indicator has its significance. If any abnormality is found during the examination, it should be reported to the physician in time, and further examination may be required to clarify the condition.
