Urinary specific gravity refers to the weight ratio of urine to water under the same conditions, and its value can reflect the patient's physical condition to a certain extent.

The same volume of urine and water is placed in an environment of 4°C, and the weight ratio of urine to water is the specific gravity of urine. Normal adult urine specific gravity should be 1.015-1.025. If the urine specific gravity value is high, it may indicate acute glomerulonephritis, diabetes and other diseases. If the value of urinary specific gravity is low, it may be suffering from diseases such as hepatorenal syndrome and uremia.

 The use of Urine Digital Refractometer to determine the specific gravity of urine is conducive to helping to clarify the physical condition, so as to achieve early detection and early treatment of the disease.
