Exercise 56

Compare reagent strip testing for urine specific gravity with osmolality and refractometer testing.

Step 1 of 3

Comparison of urine specific gravity test using reagent strip, osmolality and refractometer:

Convenience:

Reagent strip test:

• It is a convenient way to detect specific gravity in reagent strip

Osmolality:

• Specific gravity depends upon number, and density of particles in a solution.

• It is less convenient to detect specific gravity using osmolality method

Refractometer:

• The current method used in routine urinalysis that requires correcting of specific gravity is refractometer
