ADH test is based on the measurement of
(A) Specific gravity of urine
(B) Concentration of urea in urine
(C) Concentration of urea in blood
(D) Volume of urine in ml/minute
Specific gravity of urine.The amount of solutes in the urine is determined by the specific gravity of the urine (SG). It determines how much pee is concentrated relative to water by calculating the ratio of urine density to water density.
