Is Specific Gravity 1.025?

Specific gravity is usually 1.010-1.025 (normal range: 1.003-1.030) and highest in the morning. A value >1.025 indicates normal concentrating ability. A value >1.035-1.040 suggests possible contamination, very high levels of glucose, or recently received low-molecular-weight dextran or high-density radiopaque dyes.

Is 1.020 specific gravity normal?

Normal results in adults generally range from 1.010 to 1.020. Abnormal results are generally those below 1.010 or above 1.020. In patients with certain kidney diseases, USG doesn't vary with fluid intake and is called a fixed specific gravity.

Why does morning urine tend to have a high specific gravity?

The first urine of the morning is most likely to have the highest solute concentration. USG will vary based on diet moisture content, amount of water consumed, excess dietary solutes requiring renal excretion, renal function, and hydration status (see Chapter 15, Approach to Polyuria and Polydipsia).
